U-seals, Polypaks, U-cups

Top-of-the-range twin lip rod seal designed to provide a dry sealing solution in heavy-duty applications. The seal’s shell is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance. Featuring high pressure and high shock load capability, this seal utilizes the same twin lip design found in Hercules®, Sealing Products’ RTU style. With the main body of the seal molded from high performance polyurethane, this seal, incorporates a dynamically designed nitrile energizer and a tough polyacetal anti-extrusion ring. RTUB is capable of, pressures up to 10,000 psi in approved applications.

94A Durometer | Urethane Material | 2 1/4 in Nominal Inner Diameter | 1/4 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

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.
