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.

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

Worked great for my Patriot 26DBH. Make sure you set the PSI on your air compressor to about 40psi. Any higher risks blowing a line and water leakage in the spring. Ensure you bypass your hot water heater prior to blowing out the lines as well.

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.

Easy to use on garden hose.

Needed this attachment to employ my air compressor to clear the water lines in my Rockwood travel trailer. The valve allows me to let the compressor pressure up to the recommended level before opening to the trailer water system. With the water blown out it is now ready for the winter and risk of freezing significantly lessened.

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

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.

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

Worked well for my teardrop camper and pressure washer.
