If you're an HVAC guy or just someone who likes to service their own car's AC, you probably know the frustration of mismatched fittings.
This little brass adapter solves one of the most common problems.

It lets you connect a standard 1/4 male flare hose (like from your manifold gauge set) to an R134a refrigerant tank, which has a 1/2 ACME female thread.

It's a straight adapter, and the best part?

It has a built-in valve core, so you can control the flow and minimize refrigerant loss when you're disconnecting.
This thing is machined from solid brass, so it's built to last and won't corrode.

It's unbranded, but it comes with a 1-year warranty.

The part numbers cross to 15330-0P030 and 917-213, so it's a common, useful tool.
Made in China, but solid.

If you're tired of fighting with your AC gauges, this simple adapter is a must-have for your toolbox.,
