Wilden Valve Balls & Seats (Spare Parts)

An air-operated pump lives or dies by its check valves. Four balls and four seats do the quiet work of keeping flow moving one way, and as they wear the pump slowly loses prime, output and efficiency until someone finally swaps them. Keeping a set on the shelf is cheap insurance against an expensive stop.

We stock genuine Wilden balls and seats in the materials that matter — tough elastomers for general and abrasive duty, PTFE and stainless for chemical service. Matching them to the fluid is what buys you a long, leak-tight life; the wrong material wears fast or won’t seal at all.

Tell us the pump model and what it’s handling and we’ll confirm the right genuine balls and seats. In stock, ready to ship worldwide.

Fits: full Wilden range (flow / head / power not applicable — spare part)
