QYD Pneumatic Cylinder Seal Piston Rod Seal
♠Description-QYD Pneumatic Rod Seal
QY-D 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.
