Frequently Asked Questions
It matches the thread sizes and 90° street elbow form, but genuine Graco parts are selected for pressure rating and fit in Graco systems. For equipment up to 7,250 psi, use OEM-rated fittings like 164259.
Check your unit’s parts manual. Look for a listing of “Elbow, street, 3/8 NPT (M) × 1/4 NPT (F)” or the exact part number 164259 near the filter/manifold/pump outlet. If unsure, share your model/serial and we’ll verify before you order.
Apply an appropriate thread sealant for high-pressure NPT connections (avoid contaminating the flow path). Hand-start, then tighten to align the outlet orientation. Do not over-torque—tighten just enough to achieve seal and orientation.
