These will work good for my home air compressor.

My coupler for between the hose and my air compressor cracked. I purchased this one because a) it was inexpensive and b) it had a small plastic case so the little extra pieces I might use in the future wouldn't get lost. I put the new coupler on (with a little teflon tape) and it worked perfectly. My compressor doesn't leak anymore, which was super annoying. The case is good, too. I am happy and the compressor doesn't keep coming on as the air leaks out.

Nothing really special, but the options the kit provides made me pick them. The male/female options cover all the situations you could run in to. They work just fine for a home air compressor, light duty application.

I have been in the maintenance industry for over 50 years and have used many air couplers during that period these are equal or better than those I've used during this time! If you need a good set of air couplers I can highly recommend these and you won't be disappointed.

I needed a new coupler simply for the fact my old one was over 20 years old and leaking air. Put this new coupler on and what a snug fit. No more loosing air. No longer have to remove the air tool so as to not loose any additional air when not in use. Would recommend.

I’m really impressed with the WYNNsky Air Coupler and Plug Kit! The 1/4" NPT fittings work perfectly with my air compressor setup, and the industrial Type I/M fittings are built to last. The kit includes 7 well-made pieces, which made it super easy to connect everything without any issues. I was also happy with how well these fittings hold up under pressure—no leaks at all! Great value for the price and a must-have for anyone working with air tools or compressors. Highly recommend this kit for its durability, easy installation, and reliable performance!
