Vibrant Yard Co. LLC Winterize RV, Motorhome, Boat, Camper, and Travel Trailer: Air Compressor Quick-Connect Plug to Male Garden Hose Faucet Blow Out Adapter with Valve (Lead-Free Brass), 17 Long

I particularly like the in-line valve - it saves me from having to cycle the compressor on and off. Makes winterizing just that much easier.

For something I will use once a year it is just fine

Used to winterize my camper and to blow water out of some underground hose. Worked great.

This connected to my Craftsman air compressor just fine. I was able to drain my hoses with a lot less work than before, and winterizing my camper next fall will be a lot easier.

I tried the Camco version with the little tire valve on the end, but this one REALLY gets the water out, because it can flow a much higher volume of air. Based on how my compressor kept up, Id estimate you can move ~10gpm through this fitting.

Excellent product and works great not only for rvs, but underground water lines.

Works great for what I needed it for

Big suggestion to have one of this if you have a RV (and a air compressor). Save ton of money to winterize a RV by myself without going to RV dealer.

An absolutely great solution for winterizing rV’s.

Perfect
