How we verify products

Our product directory is built from individual product records rather than assumed specifications. We distinguish documented attributes from general buying guidance.

Sources and evidence

We prioritize manufacturer product pages, manuals and technical documentation. Retail listings may help confirm model identity, but we do not assume a listing proves connector compatibility or current stock.

Compatibility checks

We consider the exact product model, hose length and diameter, maximum working pressure, temperature limitations and connector type. An M22 label alone is not enough to confirm fitment: insert dimensions and equipment requirements matter.

What we do not claim

We do not claim hands-on testing unless explicitly documented. We do not invent ratings, review counts, prices or performance results. When a specification is uncertain, readers should verify it with the manufacturer.

Corrections and updates

We review source changes as the catalog develops and keep unverified product pages out of search indexing. See our editorial policy.
