Reciprocating Rod and Piston Seals

High-Pressure Piston Seals

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

High-Speed Rod Wipers

Made from MDS-filled PTFE for a slippery surface, these wipers allow rods to move three times faster than other rod wipers.

Wear Rings

Made from glass-filled nylon for excellent wear resistance and strength.

High-Speed Wear Rings

Made from PTFE, these wear rings have a slippery surface that allows rods to move at least three times faster than nylon wear rings.

Packing Seals

High-Speed Chemical-Resistant Packing Seals

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

Low-Friction Oil- and Water-Resistant Packing Seals

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.

High-Flexibility Steam-Resistant Packing Seals

Offering excellent flexibility, these seals are made of expanded graphite yarn. Use them for steam applications in pumps and valves.

High-Speed Steam-Resistant Packing Seals

Made of graphite-impregnated carbon, these steam-resistant seals dissipate heat from the shaft to protect pumps and valves when operating at high speeds.

Wire-Reinforced Steam-Resistant Packing Seals

The Inconel-wire reinforcement in these expanded-graphite yarn seals ensures they keep their shape longer than the High-Flexibility Steam-Resistant Packing Seals. Use them for steam applications in valves.

Steam-Resistant Packing Seals

Use these graphite-impregnated graphite seals for steam applications in pumps and valves.

Packing Seal Tape

For use in valves and pumps, this thin, flexible tape is made from high-purity graphite with no fibers or binders that could contaminate your process line.

Bore-Sealing Spring-Loaded Rotary Shaft Seals with Wiper Lip

Bore-Sealing Spring-Loaded
Rotary Shaft Seals with Wiper Lip

Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.
