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

Great for blowing the lines out in our camper! definitely recommend to those who decide not to use antifreeze for winterizing!

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

Easy to use and works as expected

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.

Worked well for my teardrop camper and pressure washer.

Well Built.

This is well made and makes winterizing my RV so easy

Used to blow out my flower bed irrigation. Worked great, did exactly what I needed. Satisfied customer, especially since it is made in USA.

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.

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.
