COP Piston Seal FKM Construction Machinery Seals 

O Rings Seals Type COP is a small double-acting cylinder piston seal with better friction characteristics and a unique cross-section design compared to O-rings to avoid torsional damage. For standard cylinders, small diameter cylinders and low profile cylinders. Piston Sealing COP Application: Working pressure: ≤1.0MPa Working temperature: -20℃～+80℃ Surface speed: ≤1m/s Medium:  oil-lubricated air and dry air and oil-free air (initial lubrication is required during assembly). Installation:  These pneumatic seals can be easily fitted over the piston into the groove. To avoid damage to the seal, precautions should be taken to avoid sharp edges during installation. In the case of oil-free lubrication, it is important to have a complete injection film on the sealing surface, which should be done before assembly to ensure a long working life of the seal. Material:  Standard material is NBR based synthetic…
