Molded from a PTFE base material with 40% bronze and machined to exacting tolerances, this seal exhibits low friction and high strength corners are chamfered for cold flow resistance.

40% Bronze Filled PTFE Material | 1 9/16 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

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. 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. 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.

94A Durometer | Urethane Material | 5 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

Features

• General purpose rod seal

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.

90A Durometer | Urethane Material | 1 in Nominal Inner Diameter

Features

• Slotted heel design
• Slots in the heel allow excess hydraulic fluid to bypass the wiper

This U-cup style buffer ring offers an asymmetric sealing lip profile, chamfered sealing edges, and pressure relieving capabilities to prevent inner pressure entrapment when employed in a tandem sealing system. This rod buffer seal is designed to absorb impact pressure fluctuations under high-load conditions thus increasing the life of the primary seal.

Urethane Material | 2 1/4 in Nominal Inner Diameter | Buffer 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.
