Great Product, Value
Works great with my Ingersol Rand tow behind compressor

Good Quality
The material is very good quality. The holes for the safety clips are drilled and have sharp metal that was not filed off after drilling. Other than that they work great.

Gasket dimensions?
Love the price but the fittings wouldn't push together close enough to twist into a locked position. I tried hard. I had to grind down the gaskets and then they connected well. Not a fan of rubber dust though.

Cargo net anchor straps don't hold tension
Was a two piece package no issues other than delivered to my neighbor with the air fittings. Second item in package is a cargo net from Amazon by Autofonder.

Description was accurate
Worked as described! Used on 3 different Chicago style hoses and it worked fine. I should have ordered 3/4 but bout a 1-3/4 adapter to make up the difference. Works as described!
