Yellow Jacket 40345 Blue Single Test Pressure Gauge (R22/R410A/R404A) W/12" Hose

This gauge is just what I was looking for to perform some refrigeration work. Nice resolution on the negative pressure side.

Works well like any Yellow Jacket gauge. I like the short hose to prevent losing freon on small refrigerant systems.

Easy preasy

I always but Yellow Jacket HVAC tools if possible and this gauge is high quality which is typical of Yellow Jacket.

Confirming that the picture does not match the product as noted by other reviewer’s. This gauge definitely works for R410A systems. The hose on the other hand is quarter-inch only and this was not specified in the description. If you bought a Senville mini split, you will Likely need the adapter (5/16 female 2/4 inch male). Wish I had known that at the time as now I need to wait two weeks to get the adapter in order to check my system. I just bought the matching yellow jacket adapter as it is the only one that was A five star review (with a large number of reviewers). Moral of the story is the product information does not provide you with what you need to know when you purchase this gauge. Check your air conditioner before in order to determine whether you need the adapter If you buy this gauge. I noted other reviewer‘s who bought a variety of gauges stating that they didn’t need the adapter. Obviously some air conditioners have quarter inch hook ups But mine didn’t

Worked fine.

I like these a lot better than the full manifold gauge set. Even though I have a pair. I’m not worried about refrigerant lost from putting these on

Some people have noted 1/4" vrs 5/16" port size. All mini splits I have seen have 5/16" ports. Central units have 1/4" ports. It can get a little crazy trying to find the proper hoses/fittings. All my test equipment has 1/4" fittings.
