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

Did the job perfectly!!!

You will need a pressure regulator! RVs can only handle up to 50 psi before they have problems. If your compressor is set higher than you can potentially damage the plumbing. Works great and as intended however!

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

Good quality, full brass, just what I needed and happy with purchase.

Works great!

Works perfect

I got tired of big market and the money needing to spent to winterize my camper, when I could use the phone I use EVERYDAY and research ways to do it. This little item helps me to do it! I will say this, adjust your compressor to 40-50lbs psi!! Again, 40-50lbs psi on you air compressor output!! I didn’t make that mistake but I had prior knowledge to tools, piping and pressure. Now I don’t have to worry about and chemicals in my water line other than what’s already in water.

Simple to use and it’s a must for winterizing your own RV

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

This male threaded blowout adapter arrived JUST IN TIME to help us blow out the water lines at both the cabin AND our camper this year as the night time temperatures hit 13F this past week. This listing includes a 2 pack for just a dollar more, that pack appears to include a female threaded blowout adapter as well. Both come with the quick disconnects which is another handy feature. Worked GREAT with our typical portable pancake style air compressor. Be sure to have some teflon tape on hand, some of these adapters include some tape, this one did not. We have used the Venom teflon tape in the recent past, our recommendation is just get the regular teflon tape. My husband is pleased so I am pleased, 5 stars.
