When you're running an Interpump W/WS series pressure washer for hours in an industrial setting, the last thing you need is a seal blowing out mid-shift from the heat and friction — this kit handles that scenario.
Rated from -20°C to +200°C with a Shore A hardness of 95 or above, the available material options are NBR rubber with fabric or FKM (Viton), both built for high presure and customizable to your specific pump, matching OEM specs without the markup.
It prevents plunger friction overheating and water leakage even under serious pressure swings and limited lubrication, but it's not suited for low-speed residential washers where the cheaper standdard seals work just fine, so most buyers we see are from commerical cleaning fleets.
Teh complete kit comes as a set, including all U and V type seals you need, though lead time depends on material choice — FKM usually takes a bit longer to source than NBR.
We've had machinists say the fit on these is tighter tolerance than some aftermarket options, and the fabric reinforcement in rubber makes it less likely to roll during insallation, which is a detail you'd only notice after handling a few hundred of them.
MOQ is typically 50 units or so, and we always provide a COA with each batch — just confirm your pump model number like 69/88/38 or AR1857 when ordering.
We don't have a strict MOQ, so you can order as few as one kit for testing or replacement. For bulk orders or custom specs, just reach out and we'll work with you.
Standard orders ship within 3–5 business days. If you need custom materials or sizing, lead time is usually 10–15 days depending on the complexity.
Yes, we can provide a material certification and a performance test report upon request. Our kits meet OEM specs for Interpump W/WS series, so you're getting factory-grade quality.
Absolutely, we can adjust the pressure rating and material to fit your needs. Just let us know your requirements—our FKM option handles up to 200°C, but we can also tweak it for different conditions.
Keep them in a cool, dry place away from direct sunlight and ozone sources—ideally below 25°C. Stored properly, they'll stay good for at least a year without any degradation.
