Review Image by William B. William B.
What can I say, I bought this thing because I went wireless for probes, I thought this "1 hose" setup was absolute BS until I swapped a coil and used it. WOW I mean by the time I got my micron gauge to link up to the iPad I was pulling 3000 micron and DROPPING, by the time wtf came out of my mouth and had a double take I was seeing 900's, this is a must for hvac, it did interrupt my plans for lunch though 😆 ... show more

    • 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

    • Well made hose.
Style: NHB1
This is a well made vacuum hose, I've run it down to 200 microns on a few systems and it holds vacuum well on decay testing. The thickness and stiffness of the hose is a double edged sword, yes it vastly improved the speed of achieving vacuum but it does make it awkward to use. With ¼ and ⅜ diameter hoses they're flexible enough to connect to the pump wherever you put it but because the hose is so thick and stiff it tends to dictate where you can and can't locate your vac pump. ... show more

    • 1/2” Diameter hose with 1/2” FL by 1/4” FL fittings
Style: NHB2
I will second the review by Thegun98. I bought this looking for a vacuum rated hose with 1/2” diameter hose, 1/2” female flare connector on one end for attachment to one manifold port on my Robinair 6CFM vacuum pump and 1/4” female flare in the other end for attachment to the suction line on my AC compressor unit. I was having a hard time finding such a hose as most are 3/8” flare fittings, but not this one. Even though the listing description is lacking the detail I was hoping to find, I ordered based on Thegun98’s review and was glad to see what showed up is exactly what I was looking for. 1/2” hose with one 1/2” FL on one end and 1/4” FL on the other end. ... 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.
