Use these Viton® fluoroelastomer rubber seals with fuels and aggressive chemicals, such as petroleum oil, hydrofluoric acid, and propyl alcohol.

The Buna-N foam rubber bulb on these seals also resists grease, salts, water, steam, and most detergents.

Made of fiberglass, these seals are woven tighter than High-Temperature Ultra-Conformable Slotted Edge Seals for increased durability. They resist grease, oil, hydraulic fluid, and solvents and can withstand temperatures up to 1000° F.

These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly. Also known as lip seals, U-cups have a sealing lip on both the inside and outside edges, so they can be used for rod and piston sealing.

Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston for better sealing performance at lower pressures than unsupported U-cup seals.

These seals have a beveled lip that optimizes contact against the rod, while a secondary lip keeps the seal stable.

The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our buffering seals.

A square O-ring prevents these piston seals from rocking in the groove.

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

A two-lip design means that these wipers also function as a rod seal.

These wipers seal against the cylinder housing to prevent contaminants from entering between the outside edge and the housing.

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.

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.

Swap out old seals without disassembling components—these seals come split for easy installation. They're also known as clipper seals.

These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F.

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length.

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

Aramid and PTFE fibers are blended for seals that resist chemicals and abrasion. Use these seals in pumps.

Built for high-speed pump and valve applications, these super-tough seals are made of expanded-graphite yarn with carbon-yarn corners.

These seals are made of PTFE fiber without a lubricant, so they’re harder than other chemical-resistant packing seals to handle high-pressure valve applications.

Made of PTFE-impregnated synthetic fiber, these seals are for use in pumps.

These seals require lighter packing pressure than standard oil- and water-resistant packing seals, so they cause less friction and reduce shaft wear. They’re made of graphite-impregnated aramid fiber and are for use in pumps and valves.

The most abrasion resistant of all our packing seals, these are made of PTFE-impregnated aramid fiber that has been saturated in a lubricant. They are for use in pumps.

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