Yellow Jacket 40332 Blue Compound Gauge with 19110 Quick Coupler

As a refrigeration technician, i love this gage and i also bought the high side gage. These gages are small enough to fit in my tool bag without compromising the ease and efficiency of my diagnosis bag. Another huge perk is that there is minimal discharge after attaching these. Having these gages also benefit the convenience of having them when you need them because they fit in my primary service bag, a good HVAC/R technician is not going to walk up to a service call with a pair of gages in hand because most of the time its an electrical problem. Im in commercial refrigeration so having them handy in my bag without having to run out to the truck for a pair of gages is hands down great.The cons of these this gage is that there are some tight spaces that its possible they wont fit without giving you a hard time.One complaint that i heard about these is that they dont have a specific refrigerant type and they cant use them, ok lets get real, if that is going to prevent a purchase then i dont understand because it shows the psig amount on the outer part of the gage so you can just use a P/T chart for the specific refrigerant type. Everyone use this type of gage in HVAC/R must learn how to use a P/T chart anyways. Overall great gage

Great item as advertised

Very handy, specially for quick troubleshooting. Will definitely recommend this product.

These are not as depicted in the page graphic with 1 PSI tick marks all the way down to 0. These have a white block below 5 PSI. There are no 1 PSI tick marks for 0-4 PSI making it completely useless for our purposes. Sent back to Amazon.

Exactly what you can expect from Yellow Jacket, all great stuff

It’s a great tool, very comfortable

No worries with Yellow Jacket products as always. Been in the trades of HVAC&R, DDC, Pneumatics, Etc. for 30 plus years, I only use a trusted name in this trades in the fields of commercial, industrial & residential.

Got this gauge delivered today. Not _quite_ as pictured in the description. The blue/green dial separation is under the PSIG zero, and that is as close to 0 as the gauge can be calibrated. For determining the superheat value, that difference is enough off to make it nearly worthless. It's a beautiful gauge, and the shorty coupler is incredibly handy for checking the pressure in a critical charge AC unit, losing as close to no refrigerant as you can get. But the gauge error is just not acceptable. Sorry, but returning it now. I'll get the other compound gauge to replace it, and order the coupler separately. Hopefully it will zero properly.

Buena calidad original

Great service
