Industrial Quick Coupler Standard socket · Type A / universal profile
The everyday workhorse coupler.Standard-profile socket-and-plug coupling for general industrial plants — wall outlet, hose end, tool drop. "Industrial" describes the most widely used coupling profile (Type A / universal) in US plants, not a hardware class. Ball-detent or sleeve-detent release.
Releases under pressure — hose-whip riskReleases the plug while line pressure is still in the hose, which is the OSHA 29 CFR 1910.242(b) hose-whip condition. Where the plant has no overriding budget constraint, default to the safety-vented variant instead.

Safety Quick Coupler Two-stage vent · OSHA 1910.242(b) compliant
Default for any plant with audit or safety-program exposure.OSHA / ISO 4414 compliance product, not a hardware upgrade. Two-stage disconnect — stage one vents the hose to atmosphere, stage two releases the plug — eliminates the hose-whip hazard the standard industrial coupler creates. Recommended default socket for every new install.
Premium over standard industrialModest cost premium over a standard industrial socket; the connect action is unchanged, only the release sequence differs. Standard industrial only where budget is the explicit override — and the hose-whip liability stays with the plant either way.

Quick Coupler Plug Male half · sold many-per-socket · profile-matched
Every tool, every hose end.The male half of every quick-coupler connection. Mounts on the tool inlet or hose end and pushes into the socket. A facility needs many more plugs than sockets — plugs go on every tool and every hose end, sockets only at fixed supply points.
Profile must match the installed socketIndustrial / Type A, Automotive / CA, Tru-Flate, ARO, Euro — a plug of one profile will not mate with a socket of another. Confirm the facility's standard profile before quoting and quote plugs at the higher quantity per socket.

Reading the brand bench column — the bar shows how many of SPC's tier slots carry an option at that product type. All three coupler types run two brands deep: Prevost and Aignep across industrial socket, safety socket, and plug. The spec decision here isn't brand depth — it's safety-vented vs. standard industrial on the socket, and matching the installed profile on the plug. <b>Default to the safety-vented socket on every new install with audit or safety-program exposure; the hose-whip liability stays with the plant when "standard" is chosen.</b>
