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

Rated for pressure up to 10,000 psi, these leather U-cups handle over 80 times more pressure than our Buna-N U-cups.

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.

Replace wipers in open-groove cylinders—these wipers have an integral steel case so they press fit into the groove around the rod.

Cut this stock to make wear rings that fit any rod or bore diameter.

These leather V-ring packing seals handle over twice the pressure as PTFE. Leather is tough, pliable, and wear resistant, so it flexes to fit uneven surfaces and fill voids.

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.

Softer than standard Viton® fluoroelastomer O-rings, these offer a better seal in low-pressure applications.

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.

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.

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.

All of the O-rings in these assortments are Viton® fluoroelastomer and resist isopropyl alcohol, mineral oils, and transmission fluid.

These assortments contain a mix of Buna-N O-rings that resist oil and Viton® fluoroelastomer O-rings that resist boric acid, fuels, and transmission fluid.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
