Piston Seals

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.

Glass Filled Nylon Material | 2.908 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Piston diameter “I” dimensions are given for pistons without wear rings.

15% Glass Filled PTFE Material | 3.353 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Glass Filled Nylon Material | 3.908 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

A heavy duty double-acting assembly, the capped piston T-seal exhibits excellent sealability, extrusion resistance, and wearability. T-seals with “BR” suffix utilize a Bronze Filled PTFE cap instead of the standard Glass Filled PTFE cap.

PTFE; Nylon; Rubber Material | 4.27 in Nominal Inner Diameter | Capped Piston T-Seal

Features

• Glass-filled PTFE cap, nylon back-up, rubber energizer

Piston diameter “I” dimensions are given for pistons without wear rings.

15% Glass Filled PTFE Material | 2.353 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Designed to fit on one or two piece pistons, this piston seal employs a nitrile seal for high sealability, nylon split back-ups for extrusion resistance, and two split bearing rings. No further support bearings are required.

70A Durometer | NBR Material | 50 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 | 4 3/8 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

This capped piston seal consists of a filled PTFE cap, a T-shaped NBR energizer, and two split nylon backup rings. It exhibits low friction, high sealability, and excellent resistance to extrusion and wear.

PTFE Material | 75 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Molded from 93 Shore A polyurethane with a 70 Shore A energizer, this seal utilizes the same groove dimensions as a standard o-ring or T-seal. One or two Style 575 back-up rings may be used for wider grooves. Extrusion resistant by design, this seal is also resistant to rolling and twisting. Installation is an easy two step snap-in procedure with no need to re-size before insertion into the bore. Piston diameter “I” dimensions are given for pistons without wear rings.

93A; 70A Durometer | Urethane Material | 1 1/4 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Piston diameter “I” dimensions are given for pistons without wear rings.

15% Glass Filled PTFE Material | 1.287 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities
