About these parts
Pump rubber parts take pressure and wear on every stroke. Cups and valve inserts flex as the pump runs, balls seat in the valve, and rings and packings seal the covers and liners. We make them to size, to drawing, or matched from the worn part.

Common questions
What details do you need for pump rubber parts?
The pump make and model or the drawing, the part name, its size (liner size for cups, diameter for balls), what the pump handles, and the quantity.
Can you match a worn cup bucket or valve insert?
Yes. Send the worn part or clear photos beside a ruler. We measure it and make the new part to fit.
What are liner rings with canvas?
They are rubber rings reinforced with canvas fabric, so they keep their shape and seal under the pressure in a pump liner.
