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 | 109.5 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 | 104 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
The MPSU300 is a compact, double-acting piston seal consisting of two parts: a urethane sealing ring with a pronounced sealing edge and a rectangular nitrile energizer to prevent the seal from twisting within the groove. It also has low friction and smooth operating movement even at low linear velocities.
94A; 70/80A Durometer | Urethane Material | 119 MM 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 | 6.305 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 | 11 1/8 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Some PS2000 piston seals utilize a round instead of a square energizer. Also, piston diameter “I” dimensions are given for pistons without wear rings. Many sizes shown are completely interchangeable with style PS914 piston seals.
Glass Filled Nylon Material | 4.408 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 | 6 5/32 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
This seal, molded from high grade 55D polyurethane, may retrofit the PS1800 seals, considering all dimensions are comparable. This seal material, with a high degree of memory, stretches over the piston and snaps in the groove for immediate assembly. These seals also feature low friction and high abrasion and extrusion resistance which helps to eliminate assembly damage. Piston diameter “I” dimensions are given for pistons without wear rings.
