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

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

Did the job perfectly!!!

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.

Set worked perfectly for freeze protecting my sprinkler system.

You better spend 10 dollars more but DO NOT buy that. Its a really bad and super cheaply made product

Exactly what was needed to winterize RV. Connects to compressor to blow out water lines.

Great product

Works great, however a very unusual amount of Teflon tape is needed to seal the threads.

Great product

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