Question by: Lance F on Aug 9, 2025, 2:56 PM

got a 1.50 rod, is this the right wiper size or am i gonna be fighting it?

Answer by: Customer Support on Aug 11, 2025, 6:45 AM

Fit comes down to the two sizing points given for this ST style wiper ring: it is made for a 1.50 inch rod diameter and has a 1.88 inch wiper OD, with a 3/16 inch base thickness.

Question by: Connie A on Mar 3, 2026, 9:26 PM

Got a cylinder with a 1.50 inch rod that needs a new wiper, will this one drop right in, or is there measuring I need to do first?

Answer by: Customer Support on Mar 5, 2026, 1:43 PM

For a straight swap, the key numbers to match are the rod diameter, the OD of the wiper, and the base thickness. This ring is built for a 1.50 inch rod, has an OD of 1.875 inches, and runs 3/16 inch thick at the base. Long as your housing groove matches those dimensions, it should seat right without any modification.
