What Size Whip Hose Should be Used with a 7/16" nozzle?

Don’t compromise your nozzle pressure by using a restricting whip hose

Having at least 100psi at the nozzle is a must for blasting contractors. Contractors are running their compressors for 6-8hrs/day, burning diesel at over $1.50/litre  (it’s an expensive operation). All blasting contractors should take a nozzle pressure reading every day – it’s the most accurate health check – and it takes less than one minute to do.

Have a look at the chart below with our hose size recommendations.

Nozzle Size CFM
Used at 100psi
Extension Hose ID Whiphose ID
7 7/16" 312 1 1/2" 1 1/4"
4 1/4" 103 1" 3/4"
5 5/16" 158 1 1/4" 1"
6 3/8" 229 1 1/2" 1 1/4"
8 1/2" 407 2" 1 1/2"


To make your blaster's job easier utilize a SupaFlex whip hose but keep it as short as possible. It is recommend between 10 and 25 feet of hose.
