with the valve, blowing out the water system was a lot easier

walmart.com

My husband bought this to use when winterizing our RV.  He said it worked exactly as it should.  Great product.

Canco blow out tool - winterizing RV

This part will do exactly what I bought it for.

high quality part

[This review was collected as part of a promotion.] A specialized RV part, so not easy to find. But the website had it listed.

Rarely do I give good reviews for Chinese products. No air or water leaks, excellent for blowing water lines dry to winterize RV or Boat water and waste storage tanks. Solid brass with standard tire valve stem. The Shrader valve stem can easily be replaced if it fails.

Well made

Easy to use with Viair compressor. W'ont have to flush the lines after winterizing.

better than the PINK

Excellent for blowing out excess water during winterizing

Winterizing air valve

I needed this to replace the plastic blowout valve.  Works great. I use my 12 volt tire inflator to push all the air out of my lines when I winterize my camper.
