HVAC techs and DIYers, this adapter kit is a lifesaver for working on R410A mini split systems! It's designed to convert 5/16\ female SAE charging-vacuum ports to the standard 1/4\ male SAE connections your gauges use. The kit is made from high-quality brass, so it's corrosion-resistant and built to handle high pressure. You get a valve core remover, two straight adapters, two 45° adapters, five 5V1 valve cores, five R134a hose gaskets, and five hose depressors – pretty much everything you need for charging, vacuuming, or general maintenance. The knurled coupler nuts make hand-tightening easy and secure, and the sealing design helps prevent leaks. It's compact and lightweight, so it's easy to toss in your tool bag. Compatible with most R410A mini split AC units, HVAC systems, and refrigeration equipment. If you're tired of struggling with mismatched ports, this universal adapter kit will make your job way smoother. A must-have for your HVAC toolkit!
