Yellow Jacket 19173 5/16 Female Quick Couplers x 1/4 Male Flare

Good!

works as stated good product well made

Shaped to allow hookup to my mini split unit, solid build, work great

Needed to hook up manifold gauges to most mini split service ports. Good quality. The only thing that could make it better is if it had a shutoff valve.

Buy American when you can, this is a great product

Great fit. You get what you pay for. Well done.

Good product!

works great

No leaks, works well... all brass construction. Should last for many years.

This coupler worked perfectly and the mini-split is running great!
