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

Ritchie Yellow Jacket is synonymous with quality, and this item is no exception. Perfect for coupling to minisplit AC units.

Great for working on mini splits that dont have a great amount of clearance. Ama

Worked great.

Perfect for the job thank you

works great

This adapter from YellowJacket is a must have for mini-split work. It works better than any other brand I have used. There is alot of nonsense in some of the reviews. 1. This has nothing to do with being able to use an automotive vacuum pump, nor any bearing on your guage set. Most of you will know this, but thought to throw it out there as some of the reviewing folks above probably have a service call to a pro in their future. The bend is nice as most mini-splits have the service port near the bottom and it is hard to get straight tools on. The cheap adapters leak, and the SupCo is hard to get on without loosing some gas. The large knurled surface on this one helps. I hook this up, then use an Appion tee for my probe, at that point can charge with a hose to my tank. I use my probes on mini splits to charge as you can monitor output air temp vs, suction line temp and vapor saturation. There is no conventional hi side, so it just takes some getting used to what you should see. The flare fittings on splits are the Achilles heel and you have to get them right or you will always be adding gas. The factory will always tell you to weight in at every service, but in the real world this is not possible. Use your PT chart and keep it from freezing, I have found 125PSIg to be right for me in the Texas heat, YMMV. Yellow Jacket professional quality, it just took forever to get here. Sorry for the long rant.

prefect for my Pioneer mini split 1 ton unit. this part _IS NEEDED_

as advertised, seller was fast ship. thanks

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

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