Lead-Free Brass Winterize Sprinkler Systems Blowout Plug Quick Connect Air Compressor 1/4" Adapter | Fits Garden Hose 3/4" Threading Water Blowout Adapter Fitting to RV and Campe (2)

Fits to connections well for all air water blow our needs for irrigation

I bought these to blow the coolant line out for my heater ore that was plugged. They worked great along with some other fittings I bought from Amazon.

These work, but you have to have the correct air hose connection. Most of my in-stock connections wouldn't work with this -- but I still have one that did ... so these are useful and well made.

I don't have an RV but I have several livestock tanks in the midwest. Rather than draining 100's of feet of hose a couple times a day, I started using these. I really can't say enough good about them. If I could have given 4.75 stars, I would have. Only reason I couldn't give the full 5 was the male adapter hex head is close enough to where the female end of the hose is going to be and a smaller size that without tools, it can be a challenge to get it very tight by hand.Punchline of the story is, with a manifold in the water supply line, and an air compressor attached to one of the ends. I can turn a couple levers and go from flowing water to hoses that are dry inside within a few seconds.

The dislike is - Made in ChinaThe likes are- in stock and shipped quickThe price is the price because they’re made in China!

Worked perfect

right product for the job.
