92A Durometer | Urethane Material | 5 in Nominal Inner Diameter | 3/8 in Cross Section | U-Seal

Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.

92A Durometer | Urethane Material | 7 in Nominal Inner Diameter | 1/2 in Cross Section | U-Seal

Molded from filled PTFE and machined to close tolerances, these seals feature low friction and excellent wear characteristics. Nitrile rings are used for energizers.

70A Durometer | PTFE Material | 44 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Molded from a PTFE base material with 40% bronze and machined to exacting tolerances, this seal exhibits low friction and high strength corners are chamfered for cold flow resistance.

40% Bronze Filled PTFE Material | 2 1/16 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

A double acting piston seal with many features: Two compact seal edges to concentrate the load against the dynamic surface, a cavity between the two external seal edges to retain fluid (reducing friction and wear), side grooves to allow pressure to load the energizer in all working conditions, high sealing performance at low pressure, excellent wear-resistance, and high resistance against extrusion.

97A; 70A Durometer | Urethane Material | 64.5 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Molded from a PTFE base material with 40% bronze and machined to exacting tolerances, this seal exhibits low friction and high strength corners are chamfered for cold flow resistance.

40% Bronze Filled PTFE Material | 1 9/16 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

The PS1850 piston seal can be used interchangeably with the PS1800 style piston seal. This seal provides improved heat resistance for demanding applications. Piston diameter “I” dimensions are given for pistons without wear rings.

Bronze Filled PTFE Material | 6 1/4 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

PS, 16.000 X 15.122 X 0.379 TFB

This two piece piston seal design comes made with a heat-stabilized, thermoplastic step-cut ring along with a profiled NBR energizer. This product offers extreme strength and resistance to extrusion, a very high resistance to abrasion, and ease of installation thanks to the step cut design and chamfered edges. The design also allows the seal to pass over ports without damage and offers greater resistance to surface roughness in comparison to any elastomer seals. The profiled energizer offers improved dynamic sealing ability, responding quickly to pressure changes and providing excellent sealing characteristics under a wide range of pressure conditions.
