With flat edges on all four sides, these square-profile O-rings cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections.
These durable O-rings bounce back to shape after repeated compression better than other types of Viton® fluoroelastomer O-rings.
Because one black O-ring looks just like another, these O-rings are brown for easy identification.
These are the highest purity chemical-resistant O-rings we offer. They are made and bagged in an ISO Class 7 and Fed. Spec. Class 10,000 clean room, plus they’re USP VI certified; not for use in medical applications.
Made and bagged in an ISO Class 7 and Fed. Spec. Class 10,000 clean room.
Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection. They are brown for easy identification.
All of these O-rings meet MIL-R-83248C.
In addition to resisting chemicals, such as benzene, butyl alcohol, and ethylene glycol, these Viton® fluoroelastomer ETP O-rings resist steam.
Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection. They meet MIL-R-83248.
The FEP casing on these O-rings provides the same level of resistance to harsh chemicals as PTFE O-rings, but the core material is soft to make these O-rings more compressible.
Unlike silicone, the Viton® fluoroelastomer core will continue to ward of chemicals should the FEP casing wear away.
Flexible even at temperatures as low as -60° 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.
These fluorosilicone O-rings remain flexible at temperatures as low as -60° F. They resist ethanol, ethylene glycol, and isopropyl alcohol.
Inherently softer and more compressible than PTFE O-rings, these Kalrez 4079 O-rings have comparable chemical resistance.
Able to bounce back after repeated compression, these Kalrez 7075 O-rings last longer than other Kalrez O-rings when exposed to repeated heating/cooling cycles.
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.
Kalrez 6375 O-rings are preferred over Kalrez 4079 for chemical-processing environments and applications involving steam.
Made of Kalrez 6230, these O-rings are for use when high purity is essential, such as with food and semiconductors.
While these Aflas O-rings are commonly used with petroleum fluids, they also resist many chemicals, such as ammonia, calcium hydroxide, and acetic, boric, and phosphoric acids.
These square-profile O-rings have flat edges on all four sides, so they cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections.
These silicone O-rings withstand temperatures up to 400° F or 450° F.
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.
Made and bagged in an ISO Class 7 (Fed. Std. Class 10,000) clean room, these are the highest purity high-temperature O-rings we offer.
