worked perfectly on our mirage minisplit..so it is definitely for probably all minisplits..fast shipping..great seller

This thing worked great, used it on my new mini split unit. It connects to the 410a service port perfectly. It has a built in valve depressor that my other hose adapter did not have. good purchase!!

You needed this adapter to complete the opening line for the air conditioner. So it worked really good good quality. Thanks

Does what it is supposed to.

if you are gonna install minisplit by self, you gotta have this, works great

I was not sure if I needed this when it popped up as a recommended companion item with my senville mini split, but I did need it. It has a schraeder valve in the tip which seems unnecessary. I removed the core from it for vacuum pump down

Ductless Mini Split System charging vacuum port adapter This adapter, or the equivalent Yellow Jacket 19173, is mandatory for all Pioneer mini-split systems and others with 5/16" SAE service ports. Attach this adapter using grooved pliers to tighten and thus prevent leaks, but don't over-tighten. I.e., hand tightening might leak. You can then attach 1/4" flare fitting hoses available from Yellow Jacket and others, and use a manifold set or other gauges. Before using this adapter, check to see if the Schrader valve depressor was factory installed at the female end as some apparently are shipped without them – which renders it useless. I used this adapter for a new Pioneer mini-split install to vacuum the system and it worked as designed – hence the 5 star review. Customer Photos show the adapter in use. See Comments for a step by step system vacuuming description.

Exactly what I needed to complete installation of my mini split system!!

Just the part I needed to connect to my new split unit I installed so that I could charge it. Fast delivery!!!
