U-seals, Polypaks, U-cups

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.

95A Durometer | Urethane Material | 3 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Style PU seals are molded from high quality urethane and designed specifically for piston applications.

90A Durometer | Urethane Material | 3 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

Used interchangeably for piston or rod sealing, these u-seals employ the same tough urethane material found in our, Heavy Duty Rod and Piston U-Seals.

92A Durometer | Urethane Material | 1 1/4 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Style HU seals feature a reverse bevel lip design and are molded from high quality urethane. The balanced symmetrical design makes them ideal for rod or piston applications.

90A Durometer | Urethane Material | 3 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

Designed specifically for rod applications, the short lip design and solid ‘U’ cavity provide high sealability at low pressure. At the heel, a secondary lip provides stability, friction-reducing lube retention, and some contamination resistance.

Urethane Material | 30 MM Nominal Inner Diameter | Rod U-Seal

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 | 90 MM Nominal Inner Diameter | Rod U-Seal

Features

• Excellent low temperature performance
• Easy installation

Our premium single-acting polyurethane rod seal incorporates an NBR energizer to seal at low pressures. The twin lip design provides stability and friction-reducing lube retention for dry rod sealing, and the included hard acetal backup ring resists extrusion. MRTUB is capable of pressures up to 10,000 psi in approved applications. E= European Urethane.

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.

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 seal also incorporates an acetyl anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps.

94A Durometer | Urethane Material | 63 MM Nominal Inner Diameter | Rod U-Seal

Features

• Excellent low temperature performance
• Easy installation

Molded in a tough urethane, this rod u-seal fits tightly in the groove while providing increased radial force on the rod.

Urethane Material | 32 MM Nominal Inner Diameter | Rod U-Seal

Molded in a tough urethane, this rod u-seal fits tightly in the groove while providing increased radial force on the rod.

Urethane Material | 45 MM Nominal Inner Diameter | Rod U-Seal

Utilizing tough polyurethane, these seals possess excellent wear and abrasion resistance. Symmetrical in design, they can be used in rod or piston applications. E= European Urethane.

Urethane Material | 25 MM Nominal Inner Diameter | U-Seal
