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.

90 Durometer | Buna-N Rubber Material | 5 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | O-Ring

Features

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

Used primarily as an anti-extrusion device for u-seals, these back-up rings combine high performance with very low friction. “ST” suffix designates a split ring.

PTFE Material | 6 3/8 in Nominal Inner Diameter | Backup Ring

Features

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

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 | 1 1/4 in Nominal Inner Diameter | 1/8 in Cross Section | Wear Ring

Features

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

CPO-2625 has a 2.625 in diameter with Standard Chrome. The base material is 1045 Carbon Steel with a yield strength of 75,000 psi.

ASTM A108 is the most commonly used and economical grade of shafting for hydraulic cylinder components, blower shafts, and mandrels.

• Extremely smooth surface finish
• Excellent wear and corrosion resistance
• Good strength and impact properties
• Good machinability
• Reasonable weldability
• Fair response to normal heat treating and induction hardening practices

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.

A heavy duty double-acting assembly, the capped piston T-seal exhibits excellent sealability, extrusion resistance, and wearability. T-seals with “BR” suffix utilize a Bronze Filled PTFE cap instead of the standard Glass Filled PTFE cap.

PTFE; Nylon; Rubber Material | 2.126 in Nominal Inner Diameter | Capped Piston T-Seal

Features

• Glass-filled PTFE cap, nylon back-up, rubber energizer

3 in Nominal Inner Diameter | Piston Seal

DEB-17 has a 1.75 in pin diameter.

The detachable eye bracket mounts to the rear end of a cylinder and helps prevent sideloading and wear. Can be used with hydraulic cylinders that have a standard bore size.

Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.

92A Durometer | Urethane Material | 5 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.

92A Durometer | Urethane Material | 3 1/4 in Nominal Inner Diameter | 3/8 in Cross Section | U-Seal

These seals are specifically designed with a second lip on their inside diameter and engineered to attain maximum, life and reliability in dynamic rod sealing. This feature results in reduced leakage, less friction, increased stability, and, prevents air and contaminants from entering the cylinder.

92A Durometer | Urethane Material | 1 3/4 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Features

• General purpose rod seal
• Robust design
• Excellent wear resistance
• Increase seal stability
• Performs well over wide temperature range and is extremely effective in low temperatures
• Primary lip protection
• Easy to install
