Rod Seals

MRS-93URE-22 X 33 X 4.2

MRS-93URE-28 X 39 X 4.2

MRS-93URE-80 X 95.5 X 6.3

The PU-TDI tandem seal has a urethane sealing lip with a PTFE insert secondary sealing lip. Under increasing pressure, the outer seal acts to compress the PTFE slide ring onto the rod. This action creates a high force sealing edge of low-frictional resistance. These are genuine Hunger® parts.

The twin lip design helps solve difficult rod sealing problems by providing lower friction, increased stability, and high, dynamic lip force, while preventing air penetration from outside the cylinder.

Asymmetric rod seal designed with precision trimmed sealing lips to provide a dry sealing solution in light and medium-duty applications. The Hallite 605 is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.

Designed to have interference in the seal housing groove and has a secondary lip. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The inner dynamic lip is shorter and more robust to improve sealing and compression set characteristics over conventional, symmetrical U-seals. The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are precision trimmed at an angle to give optimal rod sealing 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. 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.
