What a result looks like

Every match shows its deltas, its caveats, and its source.

An equivalent is only useful if you know exactly how it differs. No bare “this equals that” — every cross-reference carries the side-by-side spec table and a verdict.

Before you substitute: confirm the port-thread standard on your fittings and the seal compound against your air quality. Same envelope and mounting — this is not automatically a drop-in.

How we verify

Four verdicts. Never a bare answer.

Drop-in

Shared interface standard, functional specs within tolerance. Same mount, same envelope.

Equivalent — with changes

Functionally equivalent, but needs a named change: an adapter, a thread variant, a seal swap.

Application-dependent

Depends on your duty, medium, or temperature. We ask the qualifying question instead of guessing.

Can’t verify

The data doesn’t support a confident match. We say so and route you to a person — we never fabricate.

We would rather say “we’re not sure” than point you at the wrong part.
