Product Questions & Answers (3)

Question by: Dwight B on Dec 22, 2025, 10:11 AM
what's the temp range on this wiper ring? got equipment running in some pretty cold conditions and need to know if it'll hold up
Answer by: Customer Support on Dec 23, 2025, 4:49 PM
Urethane construction on this one handles a range of -65°F up to 220°F, so cold weather use are well within its limits. Whether you're dealing with a bitter winter startup or heat from sustained hydraulic cycling, it stays functional across that whole span without needing a different material grade.
Question by: Johnny H on Jul 31, 2025, 6:25 PM
got a cylinder with a 1-5/8 rod, is this ST-162 the right wiper size or am i off?
Answer by: Customer Support on Aug 2, 2025, 6:51 AM
Match the rod diameter and the wiper outside diameter. ST-162 is sized for a 1.625 inch rod diameter with a 2.00 inch wiper OD, and it has a 3/16 inch base thickness.
Question by: Todd M on Mar 3, 2026, 8:31 AM
