Review: Adapts 5/16 Mini Split A/C Unit to 1/4 Vacuum Line - This adapter will allow the use of an automotive grade vacuum pump on an R410A mini split air conditioner, which is what most of the modern mini splits use. Like all Yellow Jacket products, this is a well constructed tool, works as intended, and should last a long time. Feels solid and would probably be fine for professional use. Both connections thread on for a secure connection. There is a core depressor in the 5/16" side which connects to your mini split, and a Schrader core in the 1/4" side which connects to your vacuum line or core valve tool.
