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

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

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

A must have for professional HVAC Technicians. Pulls down HUGE systems wicked fast. Well worth the money

Great

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.

I finally broke down and bought some Appion core removers and this high flow hose. Now evacuations are much faster.

I won a new MegaFlow valve at a supply house. Bought this to run two hoses and increase the cfm. Works well

Works well

This is a great hose for use on large tonnage equipment. I do commercial HVAC and have had great success with rapid pull downs using these hoses, appion core removal tool, and a direct connection to an 8cfm vacuum pump. On smaller tonnage systems(5-7 tons) I will stick with a standard manifold setup since I feel I’d pull a vacuum below 500 within less time than setting up these hoses would take. It is a thick hose though and you need to be careful not to damage/break access ports when using it.

Me gusta la calidad con que esta hecho la manguera
