Product Questions & Answers

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

Question by: Dwight B on Dec 22, 2025, 10:11 AM

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.

got a cylinder with a 1-5/8 rod, is this ST-162 the right wiper size or am i off?

Question by: Johnny H on Jul 31, 2025, 6:25 PM

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.
