Good gauges
Nice hydraulic test kit. Gauges are quite accurate comparing to the readings from the machine. It doesn't have a PD quick connector so had to get that separate.

Excellent quality, large assortment, highly recommend.
I work on heavy duty ag equipment and often don’t have the correct gauge, fitting, or adapter, with what I’ve cobbled together over the years. Having this kit solved that issue. It is great quality and I haven’t had any issues with it for the year I’ve had and been using it. I’ve never ran into a situation now, that I didn’t have what I needed to test pressures. This kit functions flawlessly and fits nearly all applications. This is a great value for the money considering what tools trucks are asking for half this set. I highly recommend to any mechanic or diyer that works on any sort of hydraulics.

better than the more expensive brand i used to have
been using these for a while now, a bought 3 kits for my technicians and they work fine, just like the more expensive ones i used to work with and it comes with a lot of useful adapters, on one of them i had to tighten a part to stop a leak, it's good to know i think to mount the gauge just slightly hand tight otherwise you will smash the O-ring

Good product
I like the case, keeps the gauges in a safe space to ride around in the service truck. They seem to be of decent quality for the price point, all the gauges worked right out of the box with no issues. I haven’t used the run tee’s but it does come with the Parker quick coupler.

Mostly metric and Din fittings
Not the beat kit for anything US based. Yeat it cones with a ton of fitting but most are DIN or british oring. Very very few iptions for JIC ORB or ORF. all fittings are small as well so be prepared to buy a ton of adapters from your local hydraulic shop. Better off buying the smaller kit and getting the fittings you need localy.
