Winterize Blowout Adapter with 1/4 Inch Male Quick Plug and 3/4 Inch Male GHT Thread,Winterize Quick Adapter with Ball Valve for RV, Travel Trailer, Boat

My adapter arrived with teh three segments loose. I had to tighten them up. Youll need a 1, 5/8 and 9/16 wrench to do this. Vendor should do this before it ships. Otherwise it worked great. Go for it.

I use the air compressor blow out method to winterize my Class B RV. Used a schrader valve connector to my water intake, but needed the air connection that had a lock to hold air line on valve. This is so much easier and has an on/off valve too. Just what I wanted.

This worked very well to blow out the lines in my trailer. The shut off valve is helpful when having to go inside and open and close faucets.

Only thing is to tighten fittings so they don’t come apart while using adapter.

Fair price easy to use.

Nothing special about brass blowout valve, it worked great, as I suspected it would.

Works well. Was able to blow out water lines on RV for winter

It came disassembled, so I put it together with teflon tape to seal the threads. Worked great.

I got this quickly and have used it during the winterizing process for my camper. It worked perfectly and really helped to clear the water out out of the lines. I do recommend this product.

Worked good to blow the water out of my water line on my travel trailer
