SPGW

SPGW – piston seal

SPGW is a compact double acting piston seal assembly designed for one piece pistons and is suitable for low to high pressure, medium to heavy duty applications. The assembly comprises as standard a self lubricating wear resistant bronze filled PTFE cap ring, which is loaded by a NBR energiser. Thermoplastic splite anti-extrusion rings support the seal on both sides and prevent contamination of the energiser and cap ring.

SPGW piston seal is designed to be used in a variety of equipment and is particularly suited to use in earthmoving and other off-highway equipment.
