Frequently Asked Questions
No—101822 is a 5/8" stainless-steel piston ball. Some related pumps use different sizes (e.g., 3/4" 101859) or materials (e.g., ceramic). Always match the exact part number in your pump’s manual.
It installs in the piston check assembly of the displacement pump/lower. Manuals show it as “Ref. 10* BALL, piston; sst; 5/8 in. (16 mm)” for Dura-Flo 600/750 lowers and as “BALL, sst, 0.625 in.” in specific displacement pumps.
Check the parts list for your exact pump/lower. If it lists 101822 for the piston ball, you’re set. If it lists a different ball (e.g., 101859, 102972), order that specific size instead.
Follow the service manual. Keep sealants off the ball/seat, inspect the seat and guides, and torque the piston valve to the value specified for your pump model. Prime and leak-check before returning to service.
