Yellow Jacket19208 1/4" SealRight 45 Degree x 1/4" Male Flare

I have tried all the different brands and these are the best by far. If you are working with higher pressure refrigerants or walk-in freezers that don’t have a lot of refrigerant these are a must.They keep your hands safe from any refrigerant that is released and at the same time they reduced the refrigerant loss from systems that have really small charges and you cannot afford to lose any refrigerant from them.I use these with the Fieldpiece wireless probes on small compressors while checking charge. Some systems only have 16oz or less so these are a requirement!

Fits on my 1/4" hvac hose just fine. I use it for discharge side only.

These work absolutely amazing with older testo smart probe or whatever you might have in mind. These are an amazing way to not get refrigerant burns and not spray refrigerant when connecting.

Works great.

Bought as a replacement and it does the job, very happy with the purchase

The fitting I was replacing with this was the same. I was able to replace o ring and now I will put this up to use in the future.

Everything is good, I just wish that they would conceal package better whenever they put it on the porch.

Work great. They stand up to the pressures of 410A too. I use these with ball valve hoses and I don't get any frozen fingers

Can't believe I haven't had these over the years, no more frosty fingers pulling off the high side like a meatball. BUY THEM.
