Appion MH120006EAK 1/2 Diameter Hose, 3/8 FL to 1/4 FL Vacuum Certified Refrigerant Hose, 6, Black

A well made hose that makes pulling vacuum much faster, allows achieving a lower vacuum and prevents overheating of the vacuum pump.

Works well

I was surprised at how stiff and huge this 3/8 hose is. I’m told you should use large diameter vacuum hoses because the work better than 1/4” hoses. Well the 3/8” worked as good as could be expected but When I used two 1/4” hoses they performed very well too, close to the same performance when pulling a deep vacuum. If I has to do it over I’d just use the two quality 1/4” hoses and save my money.

They are stiff but if you screw it to your core removers first then the stiffness is not an issue. They can be big and bulky and unpractical if youre working on a condensing unit in a small area. Theyre not really a game changer in my opinion. Theyre nice for big equipment RTUs, chillers. But for smaller stuff you waste a lot of time just setting these big hoses up. However they do pull a fast vacuum to 500 microns. With that being said, Ill keep them in my tool arsenal. In tight areas or residential units, Ill just a 4 port manifold with a micron gauge.

but slightly overpriced. The hose made of very strong rubber, keep that in mind.

Best tools Ive ever bought combined with the yellow jacket super evac tee

Great product! appears to be well made. Makes proper evacuation much faster.

Me gusta la calidad con que esta hecho la manguera

Works too good ! Pulls under 500m in 10 mins with a 7cfm pump .

Not pictured but does come with black plastic hanger piece that both ends screw into for convenient storage
