Made of PTFE, these gaskets are chemically inert (except to molten alkali metal and elemental fluorine).

Made from PTFE with an EPDM core, these gaskets have added resiliency resulting in a longer product life.

These gaskets meet Fed. Std. Class 10,000 and ISO Class 7 clean room requirements.

These gaskets meet Fed. Spec. Class 10,000 and ISO Class 7 clean room requirements.

Even as temperatures rise, these silicone gaskets ensure a tight seal in quick-clamp stainless steel sanitary tube fittings.

These gaskets meet Fed. Std. Class 10,000 and ISO Class 7 clean room requirements.

When working with water and steam, these gaskets ensure a tight seal.

To prevent contamination in your line, these gaskets set off metal detectors if a piece as small as 1 mm wears off. They’re EPDM, so the tight seal they form in stainless steel quick-clamp tube fittings withstands moist environments.

Prevent leaks from temperature fluctuations and vibration that can loosen 37° flared tube fittings.

These gaskets resist swelling when they come into contact with oil.

Also known as Boss O-rings, these hard O-rings are for use in tube fittings with a straight-thread connection.

Able to withstand temperatures up to 400° F, these O-rings are softer than standard silicone O-rings for a better seal in low-pressure applications.

Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection.

These temperature- and chemical-resistant O-rings prevent leaks in tube fittings that have a straight-thread connection, also known as O-ring boss fittings.

Also known as Boss O-rings, these Kalrez 4079 O-rings are for use in tube fittings with a straight-thread connection. They’re inherently softer and more compressible than PTFE O-rings with comparable chemical resistance.
