Description
The Graco 101718 Steel Ball is a precision check-ball used in the inlet (suction) valve of Graco airless sprayers. During the intake stroke it lifts to admit material; on the return stroke it seats to seal the valve, preserving pressure and priming for consistent spray performance.
Why Replace the 101718 Ball?
- Worn or pitted balls can cause loss of prime, pulsation, or poor spray pattern.
- Fresh, round sealing surface restores check-valve sealing and efficient flow.
- Using the correct OEM-spec ball ensures fit and durability under high pressure.
Fit & Verification
- Match by model and by the inlet-valve assembly used in your pump lower.
- Consult your sprayer parts manual or current bill of materials to confirm 101718 is specified.
- If your unit uses a different valve family, select the ball that your assembly calls out.
Installation Tips
- Relieve all pressure and flush safely per Graco procedures.
- Disassemble the inlet/check valve; clean the seat and surrounding cavity thoroughly.
- Inspect the seat and spring; replace if worn to ensure proper sealing.
- Reassemble and torque to spec; prime and test for stable pressure and pattern.
Frequently Asked Questions

Often, yes. A worn ball or seat can prevent proper sealing. Inspect and replace the ball and seat/spring as needed, then test pressure stability.
Some catalogs reference Bedford 9-1258 as a replacement identifier. Use OEM specifications to ensure correct size and material for your valve.
