Design:
Designed for use on split pistons, the seal is a precision moulded rubber element with rubberised fabric reinforcements as style DP but with additional full width Polyacetal anti-extrusion bearing rings at each end 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 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/L has proven to be effective over a wide range of applications and is a popular alternative for existing housing designs.

These range perameters are Maximum simultaneous conditions. Optimum service conditions are affected by temperature,
speed, pressure, surface finish and extrusion gaps.
Refer to Appendix 1 for further information.
Housing
For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machining
tolerances refer to the catalogue page of selected seal. Refer to Appendix 4 for value of tolerance symbols.
Fitting
For the seal to function correctly, it is important that care be taken in fitting the seal within its housing. For a detailed checklist, refer to Appendix 3.
