Question by: Dwight B on Jul 3, 2025, 7:05 PM

got a pressure washer setup that uses quick connects all around, will this ST4M4-S male coupler play nice with standard 1/2-inch quick-connect assemblies on that kind of equipment?

Answer by: Customer Support on Jul 5, 2025, 6:21 AM

Standard 1/2-inch quick-connect assemblies are exactly what this coupler is built around. It's a male fitting in that size, so it slots into compatible female quick-connect sockets the same way any other 1/2-inch male would. Since it's a Pressure-Pro component, it lines up well with Pressure-Pro pressure washing equipment, but the 1/2-inch male format is common enough that it works with other standard quick-connect setups in wash and fluid transfer applications too.
