1 7/8″ Metal Blast Hose Coupling
Metal Blast Hose Coupling attaches to the end of any properly sized blast hose using screws provided.
The hose must be cut squarely and cleanly. The screws should penetrate the outer layer of the blast hose without perforating the inner tube. In operation, air pressure inside the blast hose helps hold the hose tight against spiral ribs inside the coupling.
