We can make gaskets in all shapes and sizes. Contact us for more info.


Our unique technical knowledge, decades of experience, and innovative thinking guarantee that we always provide the best possible solution to you.

We find the easiest and safest way for you to get the right gasket for the right application.

Each gasket is manufactured by the standards or fully custom-made to all your specific requirements, so that they provide exceptional durability even in the most demanding conditions.

Our gasket manufacturing process is effective, fast, and flexible, as we have most of the materials in stock in our warehouse.



Typical high temperature gasket material is metal reinforced graphite. Graphite can withstand temperatures from -200°C to +500°C. It also has an excellent chemical resistance against different medias. Read more from our graphite section. For even higher temperatures up to +980°C safe choice is Vermiculite based material. It has a broad chemical resistance as well as freedom from oxidation.
Usually the best option is PTFE based fully structured sealing material with right kind of a filler system. In basic applications you may use glass filled PTFE such as “blue PTFE” but it is highly recommended to use enhanced more structured materials. PTFE itself has an excellent chemical resistance against almost known medias. You may use these materials from cryogenic temperatures up to +260°C. Please read more from our PTFE section.
  We have a wide range of gasket materials for sealing oil applications. Most of our rubber bonded fibre grades can chemically withstand oil. Our recommendation for these applications is either NBR rubber bonded aramid or glass fibre. Rubber bonded fibre gaskets are recommended mainly for applications from -40°C to +150°C. Read more from our fibre gasket section. For high temperature oil applications please use metal reinforced graphite.
Our manufacturing process enables us to manufacture gaskets up to 2000mm in one piece. However, in most of the cases raw materials are in 1500×1500 sheets which then limits the size of a one-piece gasket too. This covers over 95% of the cases but in the rear cases where your need is for even bigger size gaskets, we can manufacture them for example with dovetail joints. Our high accuracy machinery will compensate the joint in the way that the joint is as tight as it ever can be.
Most of the gasket materials have their own chemical resistance charts. In other cases, please contact our highly skilled sales staff.
As rule of a thumb “the thinner the better”. Standard size flange gaskets are usually 1,5mm or 2,0mm. Gasket materials in most of the cases vary from 0,15mm to 5mm. There are plenty of even thicker materials such as rubber, cell rubber and cell plastic. If you are in doubt, please consult our sales staff.
If possible, the best option is to choose a gasket without bolt holes inside the bolt circle. Surface area has a substantial effect on the sealing outcome. With narrow gasket you will reach high surface stress which in most of the cases lead to a better sealability. In some cases, so-called full-face gasket with bolt holes is reasoned. As an example, you have a soft raw material which might be difficult to install without bolt holes or because you might have other challenges with installation. If you have any hesitation, please contact our highly skilled sales staff.
Always use dry gaskets with no lubrication. Instead remember to lubricate the bolts and washers carefully to lower the friction between the bolt and screw. If you are facing difficulties of gasket burning on the flange, try choosing a better-quality gasket with anti-stick coating.  

Use Case Examples

You can use gaskets in many different applications. To give you a better idea, we’ve featured use case examples below from Pulp Mill, Lighting Systems, and Combustion Engines.

TT Gaskets - We provide gaskets for pulp and paper mills

Pulp mill

You can find gaskets everywhere you look. Most often you cannot see or hear them, but they exist in several places in our everyday life.

Often gaskets are in use in highly demanding environments such as a pulp mill. There are number of different applications such as power plants, evaporators, fibre lines and bleaching just as an example.

Those applications are sealed with different raw materials depending on the process temperature, internal pressure, and the media’s chemical resistance requirements.

These are the applications where you do not want to save money by choosing a cheap gasket, but the biggest savings can be made by choosing a right gasket for each application.

The overall cost in the world of gaskets is the only thing you should consider.

Combustion engine

Gaskets are widely used in the combustion engines. The current requirements in health and safety has set the bar high when sealing a combustion engine.

With our experience we can help our customers all over the world seal their engines in more cost efficient and enhanced way.

Whether you are wondering how your cylinder head, crankcase or oil pan should be sealed we are happy to prove our expertise. Our experience in sealing combustion engines has roots from 1940’s and the vast knowhow is still growing.

TT Gaskets – We provide all kinds of gaskets for combustion engines
TT Gaskets - Gaskets for Lighting Systems, and Lighting and illuminaire industry and more

Lighting systems

Lighting system manufacturers worldwide are facing the same challenges and we have used to support them.

Most often the requirements for gaskets in lighting systems are not only the sealability but also isolating the light from escaping.

These gaskets are required to meet the requirements of certain fire classifications such as UL94 and sealability to meet certain IP-class. Please contact our sales staff to support.
