Product Description

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.

Worked as it should -- no leaks
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.
