U-seals, Polypaks, U-cups

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. Please consult Hercules Engineering for pressures above 6,000, psi.

The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The unique profile of the NBR energizer ensures the primary sealing lips maintain contact under low or no pressure situations while ensuring proper sealing at higher pressures. The Hallite 621 also incorporates an acetyl anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps.
