Keep your proportioner’s displacement pump running smoothly with this precision rod guide. The aftermarket Bedford 42-3654 bushing is engineered as a direct alternative to the OEM Graco 15B074, supporting accurate rod alignment to reduce wear, pulsation, and premature packing issues. A clean, stable guide helps priming recovery and consistent output on daily spray work.
