M MINGLE Garden Hose Adapter, Male to Male, Female to Female, 3/4 Inch Stainless Steel Connector, 4-Pack with Extra 4 Washers...

It fits perfectly with my garden hose, works great, its a bargain.

We use quick connects on all our farm hoses. For the money, these are a good value. Unlike some I've tried, the detent balls and retainer spring are all stainless steel. My only complaint is that they are a little sharp on the edges and you have be careful there aren't any metal shavings still inside them. As a bonus, they are compatible with the more-than-twice-the-cost (but better quality) McKillan's fittings I was buying before trying these. I'll buy these from now on.

Got myself a garden hose configuration with the hose having a filter in between my water source and pump. The filter is to ensure no bugs, dirt, oil, objects get into my pump. The issue with the filter is that it only has a output male end which also leads into my pump that pulls water in from a male end. Double male is no good but this adapter set provides a double female option to solve the issue. Used the brass option for a 3000 psi electric pressure washer and had no issues.

These hose-to-hose connectors are great. I needed to add sprinklers to the hoses in my garden in several places. I bought short 5' hoses and these female-to-female connectors to do this. It worked perfectly. These heavy-duty connectors come with black 0 rings to keep water from leaking. I will definitely buy more if I need them.

Works great, seems to be good quality
