Hey guys about the first week of december my boss gave us all testo 550 gauge manifolds. He told us we had to buy hoses for them and if we broke them its our job to replace them ect ect. I was just wondering what is a good place to get a good set of hoses? I have had standard hoses for my r-22 gauges and low loss fitting for my r-410 gauges. The guys here seem to like the ones with the valves in them Ive never used them before not sure if there worth the extra money. Seem like another thing to cause an issue
