Earlier this month, TT Gaskets leadership visited our long-standing partner Donit at 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. With this renewed commitment, both companies aim to deliver even more value to customers by combining technical expertise, material innovation, and customer-centric service.
“Donit’s capabilities in advanced material development complement our focus on high-performance sealing solutions perfectly,” says Teemu Sillanpää, Purchasing and Sourcing Manager at TT Gaskets.
“Working closely together means faster development cycles, more tailored materials, and ultimately, better service for our customers.”
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:
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.
