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

Worked as it should. It’s great to not have to use a weird “drinking safe” antifreeze in the lines of the rv this year. Or vodka in the lines. I’m not fond of flushing the lines for a half hour at the start of camping season to get them “clean”.

Fair price easy to use.

Both QC and GH fittings on the ball valve were loose and leaked air. I had to disassemble, apply teflon sealing tape, and reassemble. Not a big deal, but I didnt have tape with me when I was winterizing.

Actually, this item is three pieces combined together rather than one piece. In thinking about that, I concluded the idea has great merit since if any component should fail it can be replaced fairly easily. That would not be so if it were one cast/machined piece. I thought it would be bigger than what came but am quite satisfied with it and how it works.

Very useful for blowing water out of pressure washers and hoses prior to freezing temperatures.

This worked great when winterizing our trailer

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

really nice machining on this.

Completed winterizing RV without the hassle of putting antifreeze in water lines. Will not have to deal with cleaning antifreeze prior to next use and allows me to use RV during winter and immediately winterize. Put around 20lbs air pressure into the lines and opened all faucets to clear lines of most of the water preventing freeze damage. Highly recommended.

good
