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 | 3 15/16 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 | 3.462 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Molded in bronze-filled PTFE with an FKM energizer, this seal is used to protect the primary seal from damage caused by pressure spikes and excessive heat build up.

Bronze PTFE Buffer Material | 80 MM Nominal Inner Diameter | Buffer Seal

Parback® backup ring with a curved cross-section.

Parbaks are contoured on one face to minimize distortion of the o-ring when under pressure. Parbaks should be installed with the contoured face against the o-ring, but reversal does no harm.

90A Durometer | Buna-N Rubber Material | 5 5/8 in Nominal Inner Diameter | 3/16 in Cross Section | Backup Ring

Features

• Excellent extrusion resistance
• Easily stretched for installation
• Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces

O-rings as elastic loops that seal static and dynamic applications. They are used to seal the space between cylinders, pistons, pipes and tubes and can be made from various materials.

70 Durometer | Buna-N Rubber Material | 5/16 in Nominal Inner Diameter | 1/16 in Cross Section | O-Ring

Features

• Pressure range varies according to diametral clearance
• Temperature range of -40 °F to -240 °F

WR-NYL, 5 1/2 X 1 Wear Ring

GB-TFE-1/2×1/8-C/S

Style 590 Back-up Rings feature exceptional strength and abrasion resistance along with a 53 Shore D hardness rating which makes them suitable for high pressure service where extrusion is a problem. Primarily used as a u-seal back-up, these rings can be used with o-rings. They also retrofit urethane and PTFE back-up rings, with greater performance characteristics. “S” suffix designates a split ring.

53 Shore D Durometer | Hytrel Material | 4 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | Backup Ring

Features

• High strength and abrasion resistance
• Wide temperature range
• Chemical resistance
• Low friction
• Easy installation
