Metal-Clad Urethane Wiper Ring, 0.75 Inch Rod Diameter, 1.25 Inch Wiper OD, 0.31 Inch Height

It sure will. This wiper ring is designed specifically for rods with a 0.75-inch diameter. That's what the product specs call for.

For a 0.75 inch rod, this is the correct size. The outer diameter comes in at 1.25 inches and the height is just under 5/16 of an inch, so check that your housing matches those dimensions before installing. Urethane holds up well against abrasion, which makes it a solid choice when contamination is a regular problem. The metal cladding also helps it stay seated in the bore instead of walking around under load, which is usually what causes early wiper failure in dirty environments.
