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 | 1 11/16 in 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 | 5 5/32 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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 | 4.74 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly

The Style TP-L seal is a zero drift piston seal for bi-directional pressure applications. The locking anti-extrusion rings provide for an easier installation. It is designed to retrofit O-Ring and standard T-seal grooves. The 70 Shore A NBR is designed specifically for performance in compression type dynamic seals. Other features include a net molded dynamic sealing surface and backup chamfers.
70 Shore A Durometer | Buna-N Rubber Material | 2 1/8 in Nominal Inner Diameter | Piston T-Seal
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 | 54.5 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Molded from tough, wear resistant 55D polyester, these seals are for light to medium duty applications and are interchangeable with the style MPS seals of the same dimensions. Nitrile rings are used for energizers.
55D; 70A Durometer | Polyester Material | 119 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 | 5 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible. Piston diameter “I” dimensions are given for pistons without wear rings.
40% Bronze Filled PTFE Material | 2.634 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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 | 64 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
