    • Great product
Size: 3/8” Quick Connect
if you use the coupler and fittings together and don’t mix and match with any other fittings from different brands, they will not rust. I’ve had hoses connected together for upwards of a year or two on my pressure washing trailer set up and they still disconnect as easy as the day I assembled them no rust in sight like other things you buy at the hardware store ... show more

Size: 3/8” Quick Connect
Used this to produce a snow maker this past winter. Worked great, solid connections, no leakage, solid value.

    • Nice fit without leaks. Easy to connect and disconnect.
Size: 3/8” Quick Connect
Well-made with stainless steel, they are easy to connect and disconnect without any water leaks. I have tried other plastics and Brass, but these have been the best of the bunch so far.

    • Buy stainless steel only!
Size: 3/8” Quick Connect
These are stainless steel high-pressure washer connectors. Do not buy non stainless connectors as we have found theorist and corrode quickly. Recommended seller

    • Great with one issue!
Size: 3/8” Quick Connect
These are great Quick Connects, but I am having consistant struggle sealing them with swivel fittings and also a ball valve. Could be that the fittings aren't right but these have great quality. I'm going to keep truing, very practical though if I can get them to work. Very Durable!
