Product Questions & Answers (3)

Question by: Brenda M on Jun 27, 2025, 2:26 PM
Will this wiper ring hold up okay in temperatures that get pretty cold, like below zero sometimes?
Answer by: Customer Support on Jun 28, 2025, 8:11 PM
Urethane provides a good temperature range, rated to operate from -65°F up to 220°F. So, yes, it should handle below-zero conditions without issue.
Question by: Marvin M on Oct 27, 2025, 12:41 PM
температурный диапазон on these urethane wipers, what's the lowest they'll hold up in? got equipment sitting outside through some real cold winters and need to know if they'll still flex right come spring startup.
Answer by: Customer Support on Oct 29, 2025, 7:36 AM
Urethane construction on this wiper handles temps down to -65°F, so cold storage or outdoor winter conditions won't crack or stiffen it into uselessness. At the high end it runs to 220°F, which covers most standard hydraulic cylinder operating ranges. For equipment that sits cold and then gets fired up seasonally, this material range gives you solid flexibility across that full swing.
Question by: Norm R on May 29, 2025, 9:19 AM
got a 1 inch rod, is this the wiper that matches up or am i off on the OD?
Answer by: Customer Support on May 30, 2025, 6:23 PM
Fit comes down to both numbers. This ST style wiper is sized for a 1.00 inch rod and it has a 1.38 inch wiper outside diameter (listed as 1.375). If your setup calls for those two dimensions, it is the right match.
