4 inputs determine the right quick coupler.

A distributor-facing pre-quote checklist. If the customer answers most of these at the first call, the second call is the quote.

1. 01
   Does the plant have audit history or an active safety program?

   Sets the socket choice. Safety coupler vs. standard industrial = hose-whip liability stays with the plant when "standard" is chosen. Default to the safety-vented socket on every new install where budget isn't the explicit override.
2. 02
   What coupler profile is already standardized in the facility?

   Industrial / Type A, Automotive / CA, Tru-Flate, ARO, Euro — a plug of one profile will not mate with a socket of another. The plant must standardize on one profile or live with a mismatched-tool headache. Confirm the installed standard before quoting replacements.
3. 03
   How many plugs per socket, and what's the stocking program?

   Plugs go at several-per-socket — every tool inlet and hose end needs one, sockets only sit at fixed supply points. Quote plugs at the higher quantity and get the annual usage estimate for a stocking program.
4. 04
   Is this a new install, a like-for-like replacement, or a system upgrade?

   Like-for-like keeps the profile the facility already runs. New install or system upgrade is the moment to step up to safety-vented sockets as the default — the upgrade conversation is hard to have later; quote it now.
