Review on Aupoko Refrigerant Charging Condition Maintenance by David Pirlet

These are cheap hoses. but to be honest the price is cheap. The rubber grommets/seals on the ends of the hoses didn't last long. The knurled nuts are small and not easy to tighten. But to be fair, they cost half as much as the hoses for the yellow jacket. For me I had to spend money on better hoses. I use them everyday at work with HVAC. While not the best hoses, they have not been rated as the best. So to be honest they are not bad. But for me I had to get better hoses.
