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

Use with our compressor it clears the water lines very well.

This is well made and makes winterizing my RV so easy

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.

Worked great... Makes winterizing the vacation home a breeze... Will be using it for years too come...

Worked great for blowing out my camper lines.

Worked well for winterize of RV.

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.

Lightning fast delivery... looks like it’ll do the trick. Well packaged.

Easy to use.

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.
