Question by: Rex R on Jul 16, 2025, 6:33 AM
does this wiper fit a 2.50 inch rod or do i need to double check that before ordering
Answer by: Customer Support on Jul 18, 2025, 6:01 AM
Rod diameter on this one runs 2.498 inches, which is sized to fit a 2.50 inch rod. The groove outside diameter comes in at 2.802 inches. As long as your housing is machined for those dimensions, you should be good to go.

Answer by: Customer Support on Feb 18, 2026, 6:05 AM
For sizing, it matches a 2.498 inch rod diameter (A) and a 2.802 inch groove OD (B). If your rod and groove are those dimensions, this AN style urethane wiper ring is the correct fit.
