Excellent quality, large assortment, highly recommend.
I work on heavy duty ag equipment and often donโt have the correct gauge, fitting, or adapter, with what Iโve cobbled together over the years. Having this kit solved that issue. It is great quality and I havenโt had any issues with it for the year Iโve had and been using it. Iโve never ran into a situation now, that I didnโt 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 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.

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.
