Question by: Norm F on Mar 19, 2026, 12:49 PM
Got a cylinder with a 1.873 rod that needs a new wiper, this AN-20 the right fit for that?
Answer by: Customer Support on Mar 20, 2026, 2:48 PM
Yeah, that's exactly what it's sized for. The rod diameter on this one is 1.873 inches with a groove outer diameter of 2.177 inches, so if your cylinder matches those dimensions you're in good shape. Just make sure your groove depth lines up with the OD spec before you drop it in.
Question by: Tommy R on Jul 8, 2025, 6:16 PM

Answer by: Customer Support on Jul 10, 2025, 8:14 AM
Fit comes down to the rod diameter and the groove OD. This AN style urethane wiper ring is made for a 1.873 inch rod and a 2.177 inch groove outer diameter, so it matches those dimensions.
