Questions about this part?

Our engineers can confirm fit before you order. Contact support.

How do I find the right part for my system?

Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.

Can you help me size a pump or valve for my application?

Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.

Can you cross-reference a discontinued part?

Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
