Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps.

Commonly used in mixing and grinding equipment, conveyors, and construction machinery, these two-part seals withstand exposure to abrasive material.

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

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston 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 of Buna-N, these O-rings resist grease, hydraulic oil, and motor oil—plus mild chemicals and water.

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

These Buna-N O-rings are made and bagged in an ISO Class 7 (Fed. Std. 10,000) clean room.

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.

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

All of these O-rings meet MIL-R-83248C.

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.

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.

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.

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 silicone O-rings withstand temperatures up to 400° F or 450° F.

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.

These O-rings also resist ethanol and ethylene glycol.

Made of FDA-listed material for use with food and beverage.

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

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.

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.

Harder than standard Viton® fluoroelastomer cord stock for better wear resistance.

This cord stock is softer and creates a better seal in low-pressure applications than standard fluoroelastomer cord stock.

This cord stock is made of FDA-listed material for use with food and beverage. It resists citric acid, diluted salt solutions, glycerin, and sodium bicarbonate.

This cord stock is softer and creates a better seal than standard silicone cord stock in low-pressure applications up to 400° F.

Use neoprene cord stock to make O-rings for applications that come into contact with water.

These PTFE backup rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and many acids.

Rigid and hard with a slippery surface, these O-rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and boric nitric, and sulfonic acids.

These assortments include a mix of EPDM O-rings that resist water and steam and silicone O-rings that resist temperatures up to 450° F.

In addition to water and steam, these EPDM O-Rings resist ethanol and ethylene glycol.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.

Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads.

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.
