Z8 Pneumatic Seal is made of a polyurethane material with an injection molding process. The thickened sealing lip is specifically designed for reciprocating cylinder rod sealing applications. Besides, a pneumatic seal’s sealing orientation can be internal as with a rod seal, external as with a piston, symmetrical, or axial. With internal pneumatic seals, a housing bore surrounds the seal and the sealing lip touches the shaft. In addition, this seal requires very little lubricant.

Compressed air, both lubricated and oilfree
● The sealing lip is geometrically designed to work in oil, air, and vacuum● Solid structure● Fit tightly into the groove to ensure reliable operation● The geometry of the sealing lip maintains initial lubrication and therefore has excellent friction characteristics● Suitable for buffered cylinders● Excellent synthetic rubber, so it has a long life● Easy to install
