1/4″ couplers, plugs and connectors

The 1/4″ quick-connect standard. A plug seats into a coupler socket; each is listed in male and female thread, so the pair can be built from either end. Bodies marked self-locking latch on insertion. Grades run stainless steel 201, stainless steel 304, and brass with a rubber seal. Where a name reads "1/4 F", the gender describes the threaded end.
