Sandblast Hose - 150 PSI Abrasive Blast Hose, 1/2 to 1-1/4 in ID, Sold Per Foot

Abrasive blast hose rated 150 PSI, in four sizes from 1/2 in up to 1-1/4 in inside diameter. This is Jason Industrial 4312 series two-ply hose in the two smaller sizes and 4314 series four-ply in the two larger ones, which is the standard pairing: the small sizes are run as lighter whip hose, the large sizes carry the main blast line.

Blast hose is a wear part. The tube is a thick natural rubber and butadiene blend chosen to take abrasive strike without cutting through, and it is static dissipating, which matters because dry abrasive moving at velocity down a rubber tube generates a charge with nowhere to go. The cover is pin pricked so trapped air can escape through the wall rather than blistering it.

Two-ply or four-ply

The published working pressure is the same 150 PSI for both, so the extra plies are not buying you pressure. What they buy is wall: at the same inside diameter the four-ply hose is thicker and heavier. The practical rule most blasters use is two-ply for whip hose and short runs where handling weight matters, four-ply for the main line that gets dragged over steel all day. The sizes above follow that split as supplied.

How it is priced

This hose is priced per foot. The underlying part numbers are supplied in 50 ft coils, so tell us the total footage you need and we will confirm how it ships and whether a full coil is the better buy. Order your couplings to match: a blast coupling fits over the hose outside diameter, so the OD figures above are the ones to quote.

What else you need

A complete blast line is this hose plus a threaded pot coupling at the machine, a two-lug hose-end coupling at each joint, and a nozzle holder at the operator end. We stock all three in aluminum in matching sizes. Fit a safety cable or whip check across every coupled joint.

Abrasive sandblast hose rated 150 PSI with a static dissipating tube and pin pricked cover, in 1/2, 3/4, 1 and 1-1/4 in inside diameters, two-ply and four-ply, priced per foot. Tell the Warthog Air Compressor Store team your nozzle size and run length and we will size the hose with you.
