Made of Buna-N, these O-rings resist grease, hydraulic oil, and motor oil—plus mild chemicals and water.
Softer than standard Buna-N O-rings for a better seal in low-pressure applications.
These hard O-rings offer better wear resistance than standard Buna-N O-rings.
When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements. These resist grease, hydraulic oils, and motor oil.
Also known as Boss O-rings, these hard O-rings are for use in tube fittings with a straight-thread connection.
With flat edges on all four sides, 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.
Also known as Quattro Seals and X-rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O-rings. They also require less compression to make a seal, so they offer a longer service life.
These O-rings have eight points of contact for a better seal in dynamic applications than X-profile O-rings, plus they have eight grooves that hold lubricant to reduce friction and wear for a longer service life.
Choose these O-rings for their adherence to strict military standards for material and construction.
These Buna-N O-rings are made and bagged in an ISO Class 7 (Fed. Std. 10,000) clean room.
If these O-rings deteriorate, they can be picked up by metal detection systems.
Softer than standard Viton® fluoroelastomer O-rings, these offer a better seal in low-pressure applications.
In addition to resisting chemicals, such as benzene, butyl alcohol, and ethylene glycol, these Viton® fluoroelastomer ETP O-rings resist steam.
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.
Inherently softer and more compressible than PTFE O-rings, these Kalrez 4079 O-rings have comparable chemical resistance.
Made of Kalrez 6230, these O-rings are for use when high purity is essential, such as with food and semiconductors.
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.
These silicone O-rings withstand temperatures up to 400° F or 450° F.
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 O-rings also resist ethanol and ethylene glycol.
These O-rings withstand higher temperatures than standard EPDM O-rings.
When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements.
Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection.
Made of FDA-listed material for use with food and beverage.
These O-rings also resist ammonia, ethylene glycol, and isopropyl alcohol.
This cord stock is softer and creates a better seal in low-pressure applications than standard Buna-N cord stock.
Harder than standard Buna-N cord stock for better wear resistance.
This square-profile cord stock has flat edges on all four sides, which creates a better seal than round profile in static applications, such as hose, pipe, and faucet connections.
The X shape of this cord stock provides four points of contact for a better seal in dynamic applications than round profile. It also requires less compression to make a seal, so it offers a longer service life.
More chemical resistant than standard Viton® fluoroelastomer, this cord stock is made of Grade ETP Viton® fluoroelastomer. It resists harsh chemicals, such as calcium hydroxide, methyl ethyl ketone (MEK), and nitric and phosphoric acids.
Use neoprene cord stock to make O-rings for applications that come into contact with water.
In addition to water and steam, this EPDM cord stock resists diluted salt solutions, ethanol, and isopropyl alcohol.
All of the O-rings in these assortments are made of Buna-N. They resist animal, vegetable, and motor oils.
These O-rings are harder than standard Buna-N O-rings for better resistance to wear.
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.
The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.
PTFE gives these seals a slippery surface that facilitates rod speeds over seven times faster than our other buffering seals. They're rated for pressure up to 5,000 psi.
PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.
A square O-ring prevents these piston seals from rocking in the groove.
Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals.
Made from MDS-filled PTFE for a slippery surface, these wipers allow rods to move three times faster than other rod wipers.
Cut this stock to make wear rings that fit any rod or bore diameter.
Made from PTFE, these wear rings have a slippery surface that allows rods to move at least three times faster than nylon wear rings.
Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.
These seals have a metal case that creates a tight seal when mating with smooth surfaces.
Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.
Also known as grease seals, these are designed to retain thick lubricant at low pressure. They have a light grip on the shaft that creates less friction than spring-loaded seals.
Made from Buna-N for excellent resistance to oil and grease.
PTFE has excellent chemical resistance and withstands a wide temperature range of -110° F to 500° F.
Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to harsh chemicals. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
