CQP Nylon Quick Couplings

The 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 Operation

Clemco 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.


  • 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
