Rod Seals

These seals are specifically designed to seal on their inside diameter and engineered to attain maximum life and reliability in dynamic rod sealing.

92A Durometer | Urethane Material | 3 in Nominal Inner Diameter | 5/16 in Cross Section | U-Seal

These seals are specifically designed to seal on their inside diameter and engineered to attain maximum life and reliability in dynamic rod sealing.

92A Durometer | Urethane Material | 5 1/2 in Nominal Inner Diameter | 5/16 in Cross Section | U-Seal

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.

94A Durometer | Urethane Material | 120 MM Nominal Inner Diameter | Rod U-Seal

Features

• Excellent low temperature performance
• Easy installation

94A Durometer | Urethane Material | 45 MM Nominal Inner Diameter | Rod U-Seal

Features

• Excellent low temperature performance
• Easy installation

Incorporating a rubber seal lip, a rubberized fabric heel, and an acetal back-up ring, this seal provides excellent sealability and high extrusion resistance.

80 Durometer | NBR Material | 45 MM Nominal Inner Diameter | Rod U-Seal

Rod seal with a hard, split backup ring on each side of the sealing element. Fits a standard o-ring groove. Non-spiraling and extrusion resistant up to 5,000 psi with improved tolerances.

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.

94A Durometer | Urethane Material | 4 3/4 in Nominal Inner Diameter | 3/8 in Cross Section | U-Seal

Style RU seals are molded from high quality urethane and designed specifically for rod applications.

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

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.

Urethane Bronze Filled PTFE Material | 110 MM Nominal Inner Diameter | Rod 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.

92A Durometer | Urethane Material | 1 1/4 in Nominal Inner Diameter | 3/16 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
