Product Questions & Answers

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?

Question by: Roger C on Dec 30, 2025, 8:42 PM

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?

Question by: Darryl R on Jul 5, 2025, 3:02 PM

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.
