DPW

DPW

Designed for use on split pistons, the seal is a precision moulded rubber element with rubberised fabric reinforcements. Style DPW is fitted with clip on anti-extrusion bearing rings on the O.D. to allow larger machining clearances between the piston head and cylinder bore, and to permit higher working pressures. The Polyacetal bearing rings also support the piston head under side load conditions thus preventing metal to metal contact. The bearing rings are an integral part of the seal therefore react directly to operating pressures thus closing the extrision gap. The seal is designed with sufficient radial sectional interference that on complete assembly low pressure sealing is effected. The supporting rubberised fabric has the capability of retaining the sealing media thus assisting in reducing friction and wear. Style DPW has proven to be effective over a wide range of applications.
