Yellow Jacket 19173 5/16 Female Quick Couplers x 1/4 Male Flare

I needed this adapter fitting to service my Fujitsu split A/C system. Worked perfect.

Worked Great; Quick Shipping; Thanks

Good product -- allowed me to use my vacuum pump on a 12k Pioneer mini split AC unit.

Worked as expected for my Pioneer 9000 btu mini split.

I just bought a manifold, a tank of R410a, and 2p of this adapters, all from Amazon, planning to refill my leaking Carrier 2.5t unit. But, I have to return those 2 adapters because I found that my units service valves and R410a tank are all 1/4 without need of this adapter. So, please dont be misled by some reviews and Q&A. Most of the R410a AC units are designed with 1/4 valves as well as the R410a freon tanks, I guess. By the way, the adapter looked a good quality part.

Shipped on time. Delivered what was expected. Worked without issue.

I have several adapters but the Yellow Jacket has the most surface area to grip, shiny-ish, solid and nice.

works great

ok

what I needed.
