This electroplated cylinder liner is an aftermarket replacement part for triplex and duplex mud pumps. A cylinder liner forms the bore in the fluid end in which the piston reciprocates to move the pumped fluid, and the piston rubber seals against this bore. This liner is built from SS304 stainless steel with an electroplated surface, the materials and finish noted in its designation. The original Chinese designation is 电镀不锈钢套S304 (electroplated SS304 stainless liner). Any model or part numbers shown are used only for identification and do not imply original-equipment manufacture.

A cylinder liner is the replaceable bore in which the piston reciprocates. It is a primary wear surface in the fluid end and is matched to the pump's bore size.
