O-ring

90 Durometer | Buna-N Rubber Material | 1.171 in Nominal Inner Diameter | 0.116 in Cross Section | O-Ring Boss Gasket

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 | 4 1/4 in Nominal Inner Diameter | 1/8 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

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

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

HT-6625X6000 has a wall thickness of 0.3125 in. The ID is 6 in and the OD is 6.625 in. The material is DOM 1026 Carbon Steel and has been stress-relieved and annealed.

Full mill lengths will be cut to lengths between 12 ft and 19 ft long. Packages longer than 44 inches may have additional freight charges.

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 | 55 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Molded in urethane, this wiper is flexible enough to easily snap into a groove yet tough enough to handle difficult rod wiping applications.

Urethane Material | 45 MM Inner Diameter | Wiper

Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.

95A Durometer | Urethane Material | 2 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

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 | 1.884 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Wear rings provide a hard-wearing surface that protects the cylinder walls and the piston rod from scoring and abrasion. By maintaining alignment and reducing side loads, these rings facilitate smoother piston movement and lower friction levels.

Nylon Material | 2 1/2 in Nominal Inner Diameter | 1/8 in Cross Section | Wear Ring

Features

• Protection Against Wear
• Reduced Friction
• Extended Cylinder Life
• Operational Efficiency
