Horrible they lied about withstanding a pressure. I used it on machine that discharges nitrogen through 5 mm nozzles and pressure drops quickly

The only thing that bothers me about this is the regulator adjustment screw feels cheap, it isn’t as smooth as I want, but I’m picky. I don’t do reviews often, but this one I have to. This kit is well worth the money. I’m a mechanic by trade, busy life/not enough time so I took the girlfriends SUV to a dealership to find a slow AC leak, I told them it holds a vacuum overnight and passes a vacuum leak test, that they need to use nitrogen, got blank stares at 2 different dealerships. Long story short, they wanted to replace a bunch of parts without properly diagnosing. I bought this kit and a bottle of nitrogen, found the leak in 10 minutes and fixed it (cracked manifold that bolts to firewall/evaporator). Counting having to buy a bottle of nitrogen and this kit, I still saved myself $900 in parts and labour from the dealership.

Makes it easy to find leaks in a/c systems. High quality. I got a used tank off marketplace and had it filled.

Hooks right up to any nitrogen tank. All lines are included to hook to R12 gauges. You will need an adapter to connect to r134 i had one sonit wasnt a big deal

Compré este equipo para presurizar equipos minisplit, funciona bien, viene con su manual de uso en varios idiomas incluidos español e inglés. Los únicos detalles que le veo son la rosca que conecta con el cilindro y la salida macho de 1/4, no se me hacen “muy sólidas/resistentes”, creo qué hay que tener cuidado para que no se lleguen a romper. Aun así me quede con el artículo por la calidad de la marca. Otros detalles fueron que le tuve que poner Teflon a la rosca que va al cilindro ya que presentaba fugas en ese área y en la salida de 1/4, les comento que es la primera vez que uso este artículo, tal vez me falta “acostumbrarse” a su uso y evitar esos detalles, nada grave, ya que el nitrógeno es un gas inerte y pues lo uso en espacios abiertos. Todo bien por parte de Amazon USA, envío puntual.
