Double Acting Piston Seal - SPW is a Double acting NBR energised Bronze filled PTFE piston seal for one piece pistons, incorporating MoS2 filled PA anti-extrusion rings.

Design

Designed for use on one piece pistons, the seal assembly consists of a filled PTFE high performance outer sleeve, pre loaded and pressure energised by a precision moulded NBR element. These two components are protected from extrusion at either side by the fitting of two low friction plastic anti-extrusion rings making the seal highly resistant to shock loads as found in heavy duty mobile equipment. The housing dimensions are those used in standard metric J.I.S. cylinders.
