    • Great product so far.
Style: NHB1
Used once on my home. Tried previously using old hoses, used manifold gauge set. digital one. The old hoses either are just too small or have leaks or have contamination or permeability. This hose, and a micron gauge at the opposite point, it went pretty quick with a larger pump 9 cfm. Well made at the moment. I'll try it a few more times. ... show more

    • Works like a charm
Style: NHB1
I always used my manifold hoses to evacuate but now I dedicated this hose for pulling vacuum's with isolation valves and a Micron gage on the high side. Works a lot faster.
