Where to Use Graco 115818 Reducing Coupling

The Graco 115818 Fitting Coupling Reducing is a factory-specified coupling used to join two sections of piping or hose of different diameters — providing a smooth, leak-resistant transition between them, especially in fluid-handling or spray systems.

  • Graco spray, pump or coating machines where input/output hose or pipe sizes differ and a size transition is needed. ([source listing 115818])
  • Fluid-transfer, paint/solvent delivery or hydraulic systems requiring reduction from larger to smaller diameter (or vice versa) while maintaining flow integrity. ([industry standard for reducing couplings])
  • Maintenance or retrofit situations where existing hose/pipe sizes don’t match — reduces need for replacing entire hose/pipe by using reducing coupling.

Frequently Asked Questions

A reducing coupling is a fitting that connects two pipes or hoses of different diameters — ensuring a seamless transition so fluid or air flows without obstruction.

Because reducing coupling allows connecting mismatched sizes without needing to replace full hoses/pipes — saving time and cost while maintaining leak-free, efficient fluid flow.
