ABOUT

A pre-check, not a certification.

FitXref helps you spot a wrong replacement part before you pay for shipping, restocking fees, or a return. Pick a category — pool pump motors, well pump pressure switches, and more coming — enter what's printed on your existing part and what the seller lists for the candidate, and see exactly which fields match, differ, or still need verification.

Why this exists

Replacement-part listings routinely use catalog numbers, cross-sell titles, or reworded specs that don't map cleanly onto the original manufacturer's nameplate. A buyer comparing a listing title against a nameplate photo is comparing two different vocabularies. FitXref starts from official cross-reference documents — Nidec / U.S. MOTORS catalogs, manufacturer pressure switch specs — and asks you to confirm the same fields side by side, in the manufacturer's own terms.

What we check

Core nameplate or spec fields: horsepower, voltage, frame, cut-in/cut-out pressure, connection size, and similar.
Purchase-critical secondary fields: rotation, shaft, mounting, wiring, switch type, and comparable risk fields per category.
Whether your model number appears in an official manufacturer alias/cross-reference group, when a source lists one.

What we don't do

We don't certify safety, wiring, or installation compatibility. A field match here is a starting point, not a sign-off.
We don't sell parts. We link out to manufacturer sources and, where disclosed, to retailers as affiliate links — see our affiliate disclosure.
We don't infer a field the source doesn't state. If a cross-reference doesn't list RPM or rotation, we say so instead of guessing.

Before you buy or install

Confirm the complete specification with a qualified professional before purchase or installation. FitXref is a reference tool built and maintained by an independent site operator, not the equipment manufacturer.
