Frequently Asked Questions

It provides a secure quick-connect method for fluid hoses, allowing fast attachment and removal while preventing leaks.

The outlet is a 3/8" NPSM thread, but the inlet uses Graco’s twist-lock system, so compatibility depends on the hose or component design.

It is used in fluid pumping systems, industrial spray guns, regulators, and finishing equipment requiring quick hose changes.
