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

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

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.

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

Made it sooo easy for winterizing our travel trailer. Just hook to the city water, open the faucets and the valve one the attached hose and all the water is gone. Would recommend to anyone with an rv.

Easy to use on garden hose.

Perfect

Worked well for my teardrop camper and pressure washer.

Easy to use.

Tres Bien
