4 X 5 X 3/4 B-lip PM
Used as a companion to our “B” lip configured Style 850 u-seal, Style 855 PRC rings convert a uni-directional u-seal into a bi-directional seal.
95A Durometer | Urethane Material | 4 in Nominal Inner Diameter | 1/4 in Cross Section | Ring
The Z-Seal™ is a squeeze type seal, combining the excellent sealability and low compression set of a resilient rubber lip with the greater anti-extrusion characteristics of a hard thermoplastic base. Under low pressure conditions, the sealing lip provides its own compressive seal force. As pressure increases, hydrostatic pressure is mechanically transmitted through the elastomeric seal element into the anti-extrusion base. The applied force then deflects radially in a controlled manner, closing the extrusion gap behind the sealing lip. Under this condition, maximum sealing effectiveness is achieved.
95A 70A Durometer | Urethane Nitrile Rubber Material | 3 in Nominal Inner Diameter | 1/4 in Cross Section | Z-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 | 5 3/8 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.
