MegaFlow 1/2 in. Hose - 6 ft (3/8FL to 1/4FL) Black MH120006EAK Appion USA 

High-Speed Vacuum Hose (with 1/2" inner diameter), MH120006EAK, 1.8m, 3/8" x 1/4", Black, by Appion USA.

Large inner-diameter hoses, specially engineered in the USA for ultra-fast evacuation of refrigeration and air conditioning systems!

Now you can maximize the true potential of your vacuum pump with the MegaFlow evacuation hose featuring a 1/2" internal diameter.

Even when restricted by 1/4" system ports, using a 1/2" hose significantly reduces resistance and dramatically increases flow—especially during system evacuation.

Using just one 1/2" hose with 1/4" fittings can result in evacuation times up to 10x faster compared to a standard 1/4" hose with the same fittings!

Key Features and Benefits:

• Vacuum rated down to 20 microns

• Larger 1/2" internal diameter for maximum evacuation speed

• Extremely flexible for easy connections in tight spaces

• Will not permeate or collapse under deep vacuum conditions

• Full flow – delivers up to 16 times more flow than a typical 1/4" charging hose

• 1/4" Flare and 3/8" Flare fittings for easy connection to Appion Speed-Y, Appion valve core removal tools, and most vacuum pumps

• Pressure rating: 3200 psi burst / 640 psi working pressure
