Yes, it can fit other Graco Husky or equivalent AODD pumps if the machine’s parts diagram specifies a Hytrel® check ball for the fluid section. Always verify in the service manual.

Replace the ball if there is visible wear, cracks, deformation, or if the pump fails to maintain proper flow and check-valve operation.
