The Graco 115820 Tee Run Tube Fitting lets you split or combine fluid/air flow — giving a main line plus a side branch from a single connection, useful for spray‑guns, gauges, bypass or auxiliary hoses in pump systems.
The Graco 115820 Tee Run Tube Fitting is a factory-specified T-shaped connector that allows you to branch or merge fluid/air lines — enabling a main “run” line plus a “branch” line from a single connection point. It is useful when you want to split fluid flow to multiple outlets (or combine flows) within a spray, pump or fluid-handling system.
