What is the Graco 102922 Ball Bearing?

The Graco 102922 Ball Bearing is a precision valve ball (often referred to simply as a “ball”) used to create a positive seal against the valve seat inside fluid pressure regulator assemblies. Its hardened construction (commonly specified as tungsten carbide in regulator parts lists) helps maintain stable set-pressure, reduce leakage, and extend service intervals.

Attribute Details
Brand Graco
Part Number 102922
Component Type Valve ball (regulator sealing element)
Typical Material Tungsten carbide (wear-resistant, for reliable sealing)
Primary Application Fluid pressure regulators listed in the compatibility section
Related Service Kits Often included in regulator repair kits such as 236589 (kit contents can vary by regulator series)

Why this part matters

  • Maintains accurate regulator set-pressure and reduces pressure drift.
  • Wear-resistant construction helps resist pitting and erosion from coatings.
  • Cost-effective fix for pressure instability or leakage past the regulator seat.

Installation & Service Notes

  • Always relieve fluid/air pressure before regulator disassembly.
  • Inspect the seat and spring; replace worn components alongside the ball for best results.
  • Keep components clean; contamination accelerates ball/seat wear.
  • If the regulator has high hours or visible wear, consider a complete kit (e.g., 236589).

Frequently Asked Questions

Match your regulator model to the Compatible Machines list above (e.g., 236081, 236449, 241976, etc.). If your regulator number matches (same series), the 102922 ball is the correct valve ball.

Yes—pressure drift or leakage often indicates wear on the valve ball or seat. Replacing the ball (and inspecting the seat/spring) typically restores sealing and pressure stability.

No—102922 is specific to fluid pressure regulators. It is not a general pump check ball for typical airless pump lowers unless the sprayer incorporates one of the compatible regulators listed above.

You can replace just the ball, but best practice is to install a full regulator repair kit (e.g., 236589) when there’s significant wear. This refreshes the ball, seat, spring, and O-rings.

Avoid dropping the ball or striking it against hard surfaces. Clean parts thoroughly and reassemble per the regulator service procedure. Proper filtration prolongs the life of the tungsten carbide ball and seat.
