CQP Nylon Quick CouplingsThe Clemco fiber-reinforced nylon quick couplings attach to blast hose to facilitate connecting blast hose to blast machine, blast hose to blast hose, and blast hose to quick-coupling nozzle holders. Description of OperationClemco nylon quick couplings attach 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. Using a quarter turn, the blast operator connects the quick coupling to any other quick coupling or quick coupling nozzle holder. A built-in lock-spring on the coupling keeps the couplings securely connected. All blast hose coupling connections should be secured with safety cables. Advantages" Fiber-reinforced nylon material springs back from most impacts that would dent or deform metal couplings" Built-in lock-springs eliminate need for safety pins" Lighter weight than metal couplings" Injection molded for precise dimensions, ensuring positive fit Coupling Description CouplingStock No. Gasket KitStock No. CQP-1 fits 3/4" ID x 1 1/2" OD hose 08412 08852 CQPS-1 fits 1" ID x 1 1/2" OD Supa hose 21088 21584 CQP-2 fits 1" ID x 17/8" OD hose 21711 21584 CQPS-2 fits 11/4" ID x 17/8" OD Supa hose 08413 08853 CQP-3 fits 11/4" ID x 25/32" OD hose 08414 08853 CQP-4 fits 11/2" ID x 23/8" OD hose 07714 08853 Available Literature:21971 - Supa Blast Hose21972 - 2-Braid Blast Hose21973 - 4-Ply Blast Hose21974 - CFP Threaded Quick Coupling21976 - CQP Nylon Quick Coupling07765 - Clemco Ultralight System Color Brochure21970 - Blast Hose Safety Cable TDS
