PPZ Hydraulic Piston Seals FKM Material KVK Seals 

PPZ type cylinder seals are used for cylinders and valves. This double-acting seal has low friction and has two miniature seals with grease accumulated in the middle. PPZ Piston Seal NBR application range: Working pressure: ≤1.2MPa 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 of NBR O Rings:  This type of pneumatic seal can be simply put on the piston and installed in the groove. In order to avoid damage to the seal, measures should be taken to avoid sharp edges during installation. In the case of no oil lubrication , It is important to have a complete lubricating 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 rubber with a hardness of 70 degrees. Metr…
