Our Sealing Solutions


The O-ring is the most used sealing product in the world and is an efficient sealing element for both static and dynamic applications.

More about O-Rings

Rubber Seals

Though O-rings are ideal for a wide variety of applications, they are not the best solution to every design problem. We offer a wide range of alternative sealing solutions including custom made seals.

Blue PTFE spring energized seals

PTFE Seals

PTFE, or Poly Tetra Fluor Ethylene, was discovered in 1938 by Du Pont and has extraordinary material properties. A complete range of PTFE parts is offered by us, from Back-Up Rings to spring energized seals and custom made parts.

Metallic Seals

Metallic seals are designed to make a seal by means of a ‘first line contact’ or ‘wedge action’ between the counter face (e.g. a flange) and the packing. In order to guarantee a proper, reliable seal, it is crucial to make the right choice of profiles and material.

O-Rings Class A+

Normally an O-Ring will create a block and seals. For this specific application a controlled leakage was mandatory and standard O-Rings failed due to the existing tolerances.
