NO WAY
The HVAC school I used to teach at, bought 20 sets of gages, which included the manifold, gages and hoses. The hoses were rated at 2000 psi and they would burst at 50 psi. The sets were made in china. Good thing the school only paid $19. 99 a set.
What ****** me off was the fact that I had set up a good discount on some quality JB presure gages sets, and was told I should mind my own business. It took a year to get more sets and was one of the reasons for me quiting. I remember when the owner had to cover a class of 20 students and it was there turn for learning how to use them. When I returned from vacation there were new JB sets there and he paid more for them than what I had negotiated a year earlier.
As said prior, YOU GET WHAT YOU PAY FOR
