JPGW seal is a double acting compact seal,consisting of a PTFE seal for dynamic reciprocating motion, an elastomer o ring and two back up rings used to compensate for large extrusion gaps and uncompressed structural deformation.
Excellent dynamic & static sealing performance
Large extrusion gap allowed
Handling safely even in dirty media
No crawling when starting, work smoothly
Long service life
Simple groove design
JPGW seal is applied in hydraulic reciprocating systems, especially good at long strokes and a wide range of fluids and high temperature working conditions. Mainly used in cylinder piston seals for heavy-duty or construction machinery, such as excavators, heavy-duty hydraulic cylinders, etc. To avoid damage to the seal lip during installation,chamfers of the housing must be smooth. Sharp edges and burrs of the seal mounting area must be removed.
In the case of proper selection of O-ring material, almost all fluids are compatible. For example,petroleum base hydraulic oil, water glycol hydraulic oil, oil-water emulsion hydraulic oil...
