O-Ring Loaded Seal, J-Shape
Having a unique J-shape profile, this o-ring loaded seal is a combo of PTFE-filled seal and a GB/T3452.1-2005 compliant o-ring. The sealing device is mostly used as a dynamic seal on a reciprocating piston rod in your hydraulic or pneumatic system, though it can be used as a static seal as well.
