Piston Seals

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 | 70 MM 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 | 25 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

The PS1400 seals offer low friction and high strength in a compact double-acting piston seal design. The PTFE seal ring, combined with a rubber energizer, assures positive contact with the dynamic surface. The PS1400 is designed to fit ANSI/B93.32-1973 groove standards. Piston diameter “I” dimensions are given for pistons without wear rings.

15% Glass Filled PTFE Material | 9.482 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Totally interchangeable with Style PS1400 PTFE piston seals, Style PS1500 piston seals are molded from tough 60 Shore D durometer polyurethane. During the molding process, a .002” thick band of molybdenum disulfide is molded into the outside diameter of the seal ring for reduced friction. PS1500 piston seals are easily stretched over the piston and recover rapidly with the elimination of the “cold flow” characteristics found in PTFE seals. Piston diameter “I” dimensions are given for pistons without wear rings.

60 Shore D Durometer | Polyurethane Material | 1.981 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

The PS1800 provides low friction, high strength piston sealing. The PS1800 also provides double-acting piston sealing in a compact design that meets the requirements of ANSI/B93-32-1973. Piston diameter “I” dimensions are given for pistons without wear rings.

15% Glass Filled PTFE Material | 2 7/16 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 | 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

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.

55D Durometer | Glass/PTFE Filled Polyurethane Material | 5.754 in Nominal Inner Diameter | Piston Seal
