“I enjoy seeing how something once unfamiliar becomes part of my daily flow”
August 7, 2025
Sanni-Sohvi Kujanpää joined TT Gaskets in early 2023, transitioning from the construction industry to manufacturing. The shift was significant, but for her, it was the right move.
“I’ve been happy with the change,” she says. “There’s been a lot to learn, and that’s exactly what keeps me motivated.”
As an Inside Sales Engineer, Sanni-Sohvi plays a vital role in supporting both customers and the sales team. Her daily tasks include quotation calculations, updating pricing, responding to customer inquiries, and assisting sales representatives, for example, by creating item codes and ensuring that everything flows smoothly behind the scenes.
From new beginnings to confidence
Though her job title has remained the same since day one, her expertise has grown rapidly.
“With time and experience, tasks that once felt unfamiliar have become routine. It’s incredibly rewarding to look back and see how far I’ve come,” she reflects.
This continuous learning and the opportunity to help both customers and colleagues is what keeps her inspired. “I like the feeling of growth, when something clicks, and you realize you’re getting better at what you do.”
Empowered to work smart
Sanni-Sohvi describes TT Gaskets’ work culture as people-oriented and empowering.
“There’s a real sense of trust,” she explains. “I have the freedom to plan my workday in a way that suits me, which makes it easier to keep a good balance between work and free time. And being able to work remotely adds to that flexibility.”
She also highlights the warmth and support of her colleagues as one of the best parts of the job. “You’re not just seen as a role, you’re seen as a person. That makes a difference.”
Everyday moments that matter
While she can’t pinpoint one standout moment, Sanni-Sohvi says she’s genuinely enjoyed building relationships with her coworkers, both at work and beyond it.
“Business trips have been a completely new experience for me, and I’ve found them really enjoyable.”
Outside of work, she’s passionate about CrossFit and golf, though she admits she’s also a bit of a homebody. “On weekends, I like to slow down and spend time with friends and family.”
And if you ask her to share a fun fact about herself?
“I’m not interesting,” she says with a grin. But anyone who knows her would say otherwise.

Travel & Attendance Info
A limited number of hotel rooms have been pre-booked for the event. Those interested in attending are encouraged to express their interest early. Attendees will be selected based on relevance and capacity.

Juli 1, 2025
Earlier this month, TT Gaskets leadership visited our long-standing partner Donitat their headquarters in Slovenia to reaffirm and elevate our collaboration, one that is critical to our strategy, values, and the future of sealing technology.
The visit marked the signing of a new partnership agreement between TT Gaskets and Donit, a significant milestone built on mutual trust, years of cooperation, and a shared vision for excellence in the gasket industry.

Together, TT Gaskets and Donit represent over 150 years of combined experience in the sealing and gasketing sector. Our continued partnership enables us to offer unique solutions, drawing on Donit’s world-class R&D and material production capabilities, such as:
Tesnit® BA-soft – an innovative sealing material designed for low bolt load applications
Tesnit® BA-KTW-G – specifically engineered for hot and cold drinking water and gas supply systems
Both materials are recognized across industries for their performance, durability, and regulatory compliance in demanding environments.
Beyond products and technologies, the visit also strengthened the human connection between our companies. It was an opportunity to align not only on technical goals but on shared values: long-term commitment, open communication, and delivering results that customers can trust.
“This partnership is more than a contract, it’s a strategic alliance,” adds Petri Lehtinen, Business Director at TT Gaskets. “Donit is not just a supplier; they are a vital extension of our team and our mission to deliver high-performance, sustainable sealing solutions to the world.”
We look forward to many more years of close cooperation with Donit as we continue to develop next-generation sealing materials and solutions for customers across industries.
TT Gaskets Strengthens Leadership Skills with Change Management Training in Tampere
Juni 30, 2025
As part of its commitment to continuous development and adaptive leadership, TT Gaskets recently conducted a full-day Change Management training session for all supervisors, managers, and HR representatives. The training was held at the Varala Sports Institute (Varalan Urheiluopisto) and delivered by Lecklé HR Lead Oy.
The session was facilitated by Tuomas Tuokkala, Development Manager at Lecklé, who led participants through a structured exploration of how ongoing change affects individuals, teams, and workplace culture as a whole.
In preparation for the training, participants were encouraged to reflect on recent changes within the company, including how these have been experienced and what impact they’ve had. The training itself included interactive group work, focusing on identifying key strengths, weaknesses, opportunities, and threats (SWOT) related to change management at TT Gaskets.
The goal was to generate practical and forward-looking ideas for how to better lead through change, with a strong emphasis on communication, transparency, and shared responsibility across the organization.
„At TT Gaskets, we don’t just adapt to change, we want to guide it with intention and purpose,“ said Aleksi Arpiainen, CEO of TT Gaskets. „This training gave our leadership team a valuable opportunity to reflect, connect, and build the tools we need to lead through transformation more effectively.“
“People are at the heart of everything we do,” added Petri Lehtinen, Business Director at TT Gaskets. “As a family-owned company, we believe in growing together, and that means investing in our people, supporting their development, and building a culture where collaboration and care are present in every part of the organization.”
One of the clearest takeaways from the session was the importance of keeping teams informed and aligned, especially during periods of intense change. Participants noted that while the company is managing many transitions, improved internal communication can help ensure that no one is left behind.
TT Gaskets extends its thanks to Tuomas Tuokkala for the engaging facilitation and all participants for their active contribution to the discussions and outcomes.
This session is part of a broader effort to ensure that TT Gaskets remains agile, collaborative, and future-ready, even in times of transformation.

Family, Learning, and Leadership: Riitta-Liisa Arpiainen and TT Gaskets at the 2025 Women Educators Conference in the USA
Juni 16, 2025
Photo: Riitta-Liisa Arpiainen proudly carrying the Finnish flag at the opening ceremony of the 2014 Women Educators International Convention in Indianapolis, USA.
This summer, TT Gaskets North America Inc. will proudly serve as the lanyard sponsor of DKG, the Women Educators International Conference in New Orleans (July 31 – August 2, 2025). But for us, this isn’t just a sponsorship, it’s a meaningful bridge between our company’s values and a long-standing family connection.
To celebrate this partnership, we sat down with Riitta-LiisaArpiainen, a dedicated educator and long-time member of this International Women Educators society, who also happens to be part of the TT Gaskets family. Her story is one of deep commitment to education, cross-cultural connection and leadership.
A Journey Rooted in Curiosity and Connection
Riitta-Liisa first joined this society in 2005 while teaching at Tampere University of Applied Sciences. Encouraged by a friend, she was drawn to the society’s focus on collaboration and cultural exchange. “This organization gives you as many opportunities as you want,” she said. She quickly became active in the Tampere chapter and, soon after, attended her first European conference in the UK.
Since then, she has participated in numerous international conferences and conventions, often gathering over 1,200 women educators from across the globe. “Every time we meet, we share ideas, experiences and build a stronger global network,” she shared. “Finland may be known for its outstanding education system, but there’s always something new to learn from everyone.”
Leading with Purposes
Throughout the years, Riitta-Liisa has taken on several leadership roles within this society, including serving as President of the Finnish Society, participating and chairing many international committees e.g. leadership, scholarship and marketing committees, and now being a member in the international Nominating Committee, which helps to select society’s future international leaders.
“This is a volunteer-based society, with elections every second year. It gives women the opportunity to grow into leadership, from being a member one day to becoming an international president,” she explained. “You just need time, energy, and belief in yourself.”
The Bridge Between TT Gaskets and Women Educators
Although not involved in TT Gaskets’ day-to-day operations, Riitta-Liisa sees a natural alignment between the values of this society and the mission of our company.
“Lifelong learning is the key. At TT Gaskets, we always talk about learning together with our customers. This society is the same, you support others and get support in return. And now, with TT Gaskets expanding into the North American market, it feels like the perfect time to build this bridge.”
Her pride in seeing TT Gaskets’ name on the lanyards at this year’s New Orleans conference is deeply personal. “I’m just so proud. In business there are some risks when making decisions like this, but I truly believe it will turn out well. I’ll be walking around with the lanyard on, full of pride.”
A Message to Women Educators
When asked what message she’d like to share with the women attending this year’s event, her answer was simple yet powerful:
“You can do it. You just need to believe in yourself. Stay realistic, things don’t happen overnight, but keep working hard and stay positive. You are the right person to do many different things.”
At TT Gaskets, we believe the same. That’s why we’re honored to support this incredible event and the educators behind it, those who empower others every day, and who remind us that learning never ends.
World Environment Day 2025: Tackling Plastic Pollution with Green Delivery
Juni 5, 2025
At TT Gaskets, we believe every step toward sustainability matters and that includes how we deliver our products. With packaging identified as one of our biggest environmental impact areas, especially due to the use of plastic, we knew change was needed.
That’s why we launched our Green Delivery initiative a targeted effort to reduce plastic in our packaging materials and transition to smarter, more sustainable alternatives.
This year’s World Environment Day centers on the urgent issue of plastic pollution. For us, it’s a timely opportunity to highlight one of our clearest success stories and to reaffirm our long-term commitment to change.
Cutting Plastic, One Roll at a Time
At TTG, one of the biggest environmental impacts relates to the use of plastic in packaging materials, and we’ve been actively working to reduce this through our Green Delivery initiative. One clear success is our shift from plastic tapes and labels to paper-based alternatives:
In 2024, our consumption of plastic tapes and labels was 81% lower than in 2022, thanks to this transition.
As a result:
Total material consumption from tapes and labels decreased by 35%
Related emissions dropped by 51%
On top of that, we’ve increased our use of paper-based tapes and labels by 200%, replacing plastics with recyclable, more environmentally friendly materials.
These results are not just encouraging — they show what focused action and cross-team collaboration can achieve. And they prove that even everyday materials like packaging tapes can make a measurable difference in sustainability.
Why It Matters
Plastic pollution remains one of the most pressing global challenges. It’s persistent, difficult to recycle, and widely used across industries, including manufacturing and logistics. For us, that means we have both a responsibility and an opportunity to lead by example.
Our Green Delivery initiative is helping to reduce waste, emissions, and reliance on virgin plastic — while making our packaging easier to recycle for our customers.
And This Is Just the Beginning
Reducing plastic in tapes and stickers is just one piece of a much bigger picture. We’re now turning our attention to other packaging components, exploring low-emission logistics, and continuing to identify ways to improve our overall environmental performance.
Stay tuned for more actions as we continue to rethink, reduce, and improve, one delivery at a time.
