Designed for hydraulic cylinder rod sealing applications, the KW Style Urethane Wiper Ring, 1.38 Inch Rod Diameter, 1.75 Inch Wiper OD, 0.190 Inch Base Thickness is manufactured by Hercules Sealing Products from urethane, a material well-suited to the abrasion and contamination resistance demands of mobile and industrial hydraulic systems. The KW style wiper ring fits a 1.375-inch rod diameter with an outer diameter of 1.75 inches and a base thickness of 0.190 inches.
Urethane construction supports a service temperature range of -65°F to 220°F, making this wiper ring a reliable choice across a broad range of operating conditions. Wiper rings of this type are used to exclude dirt, debris, and moisture from rod seals as the cylinder rod retracts, helping to extend seal service life in demanding environments.

Question by: Roger C on Dec 30, 2025, 8:42 PM
Been running a 1-3/8 rod on one of my cylinders and the wiper's shot. This KW-1375 gonna drop right in without any fussing around?
Answer by: Customer Support on Jan 1, 2026, 6:53 AM
For a 1.375-inch rod diameter with a 1.75-inch outer diameter bore and 0.190-inch groove depth, this ring matches up exactly to those dimensions. Hercules cuts these to spec, so fitment on a standard KW-style groove should be straightforward. Just make sure your groove depth and OD bore match before pulling the trigger.

How warm can these wipers get before they start to give out?
Answer by: Customer Support on Jul 7, 2025, 6:24 AM
Urethane construction supports a service temperature range from -65°F all the way to 220°F, so it's a pretty reliable choice in a lot of different operating conditions.
