Yellow Jacket R134a Couplers 41337 & 41338

5.0

The Yellow Jacket 41337 and 41338 R134a Couplers worked perfectly. The manual feature allows you to safely install the coupler under no pressure before opening the Shrader valve. I was able to pull a full vacuum and hold it before charging the system with R134a. The old automatic couplers I had would leak and could not hold the vacuum. These couplers are expensive but worth every penny.

This is a must have item for servicing and testing R134a A/C systems in automobiles. They are built heavy duty to give you years of service, so don't waste you money and time on a cheap coupling.

I must admit that the stock photo doesn't due it justice. This item is extremely well built, so I now understand why it costs $50 . And, I bought two, both Low and Hi side.
