Your cart is empty.New R410A Ductless Mini Split Systems are usually equipped with a different charging port size to avoid charging of wrong refrigerant into the system (i.e. R22). This new port size is 5/16" SAE and some gauge sets carry 1/4" SAE connectors. Port adapter converts the 5/16" SAE ports to use with 1/4" SAE gauge sets.

Had a poor performing Mini Split system after 6 years of use. Used this system with some refrigerant and stop leak to get the system back up and running. The system cooling was working just fine, but wouldn't heat during the winter. It is now working perfectly.

Exactly what I needed. Had a mini split installed in my garage, but the vacuum guage hoses used for the typical residential AC units are a different size than what is needed on the mini-split condenser. This adapter is all you need, and I ordered it so my HVAC tech could finish the install. This is for Pioneer products, but I have a Mr.Cool unit and it works just fine (same size connecter, which by the sounds of it is the standard for most mini's)

Glad I bought these. I have used them quite a lot this summer and they have worked very well. If you do a lot of ductless split systems then I would recommend this as a must have.

Ductless Mini Split System charging vacuum port adapterThis 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.
