Identifying characteristics of each hydraulic, pipe, and instrumentation connection standard used in fluid power and plumbing systems. For each connection type, gives the governing standard, seat or flare angle, whether the thread is tapered or parallel, how the seal is made, and interchangeability notes with other standards. Answers the recurring field question 'what kind of fitting is this?' — the identification step that must happen before any cross-reference or adapter lookup.

Provenance — what every record carries

Every record carries source (the URL the value was read from) and source_quote (a verbatim quote from that page stating it). A value you cannot check against its page is indistinguishable from an invented one; these can all be checked. Each record is also individually addressable on the canonical site at its url.

Licence position

Factual compilation of connection type characteristics from a manufacturer's published identification guide. Individual facts (standard number, seat angle, thread type) are not copyrightable; short attributed quotes link back to the source page.

Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
