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.

70A Durometer | Nitrile Material | 80 MM Nominal Inner Diameter | 5 MM Cross Section | O-Ring

Features

• Chemical resistance
• Temperature range of -40 °F to 220 °F

Molded in a tough urethane, this seal employs an additional lip near the heel. The twin lip design provides stability, friction-reducing lube retention, and some contaminant resistance. VME – Secondary lip is further from heel than standard MRTU. NOTE: E = European Urethane.

Urethane Material | 56 MM Nominal Inner Diameter | Rod U-Seal

Features

• Excellent low temperature performance
• Easy installation

Fabricated from fine woven fabric and phenolic resins, this wear ring is strong yet light weight with an excellent wear rate.

Phenolic Material | 35 MM Nominal Inner Diameter | Wear Ring

Features

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

Grade 8 nylon insert lock nut. The thread size is
2.5 in – 12 UNF and the nominal hex is
4 in.

Grade 8 lock nuts have a nylon insert in the nut that allows the nut to grab the fastener. This keeps the nut from backing off due to vibration.

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.

Hercules® Sealing Products is pleased to introduce our new line of PowerbandTM tight tolerance premium wearrings. Manufactured from a highly engineered blend of premium nylon, glass fiber, and PTFE, PowerbandsTM offer a high strength wear-ring for all cylinder applications, including those with minimal lubrication. And, with a Coefficient of Friction nearly 50% lower than our standard product, your cylinders will run smoother and more efficiently than ever. All PowerbandsTM are fully machined with cross-section tolerances of only ±0.001”, chamfered corners, and scarf or angle-cut end gaps. Compared to standard tolerances of ±0.0025”, this tightened tolerance improves the alignment and concentric operation of cylinder rods and pistons. The fully machined chamfered corners will better accommodate cylinder housing grooves, further improving piston and rod alignment. Lastly, the scarf-cut end gap reduces the loss of bearing support that may occur during cylinder side-loading. When combined, these features reduce the tolerance stack-up within the components of the cylinder. As a result, your cylinders will operate more consistently and be capable of operating at higher pressures and higher side loads than with standard wear-ring products. Furthermore, with this improved cylinder operation, your seals will last longer and the life of your cylinder will be extended. PowerbandsTM are currently available in our most popular wear-ring dimensions.
