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.

Unlike silicone, the Viton® fluoroelastomer core will continue to ward of chemicals should the FEP casing wear away.

Made of Kalrez 6230, these O-rings are for use when high purity is essential, such as with food and semiconductors.

Kalrez 6375 O-rings are preferred over Kalrez 4079 for chemical-processing environments and applications involving steam.

Flexible even at temperatures as low as -80° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol.

Made of silver-plated 321 stainless steel, these O-rings can handle extreme pressure up to 11,000 psi. They resist grease, hydraulic oils, mineral oil, motor oil, and synthetic lubricants.

These O-rings also resist ethanol and ethylene glycol.

When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements.

These 325-piece assortments mean you’ll always have a backup ring on hand.

PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.

In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring-energized seals.

Made from PTFE, these wear rings have a slippery surface that allows rods to move at least three times faster than nylon wear rings.

Made from glass-filled nylon for excellent wear resistance and strength.

PTFE has excellent chemical resistance and withstands a wide temperature range of -110° F to 500° F.
