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

Had the simple one, but lost it. This one works much better. Love it.

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.

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

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

Used this in addition to a couple other parts to do a back flush of the oil cooler on a Ford 6.0. Worked as advertised! truck is running cooler now.

This is a “must-have” item for any RVer. It makes hooking up a compressor and purging water lines to winterize a snap! The ball valve works smoothly and it is made of high quality materials.

I am new to RVs, and this being my second winterization, I decided to blow out the lines instead of gravity draining them. This connector has a hose which made it nice with a side mounted input, the valve made it easier while the compressor caught up.

Well made. Love the valve at the connection to the water port. Easier than going back to the air compressor. Makes winterizing easy peasy…

did the job as it should!! Winterization complete!!

Blew out my rv water lines with this and it worked great. Really like the valve on the unit.
