Product review (5 stars): Well done "Uniweld"!
It came a lot quicker than I had anticipated!  It does a great job and It had the ability to install a quick connect fitting for my air compressor with no problems!  I love it for the quality and the amount of air pressure it can withstand,  although I will never need to max it out!  I think that no more than 60psi is plenty sufficient for any car a/c unit flush!  Well done "Uniweld"!  Would buy again with no problems!
