Specifications

Part Number 101190
Description Ball, Steel (check-ball for pump/check-valve assemblies)
Material Steel / corrosion-resistant
Typical Use Lubrication & circulation pumps; select Graco pump assemblies
Fitment Guidance Install only when your equipment parts list calls out 101190

Fit Guidance

  • Model names can vary by ratio (e.g., 3:1, 6:1, 35:1, 40:1). Confirm by part number, not just model family.
  • If your pump is experiencing back-flow, loss of prime, or poor check-valve sealing, a worn ball may be the cause.
  • When replacing, inspect the matching seat and related check-valve components for wear.

Frequently Asked Questions

Fitment is by part number. If your equipment’s parts manual lists 101190, it’s the correct replacement. If not listed, do not substitute without OEM guidance.

Only if the pump assembly inside that machine specifies 101190. These families use multiple pump types; always validate against the correct parts diagram for your exact model and revision.

Back-flow, loss of prime, pulsation, or difficulty maintaining pressure can indicate a worn ball or seat. Inspect both the ball and mating seat during service.

Clean the cavity and seat, ensure correct orientation, and avoid contaminating the sealing surfaces. Replace related seals if the manual recommends a kit during service.
