Product Questions & Answers (3)

Question by: Sheila H on Jun 16, 2025, 5:17 PM
got a rod that mics out right around .935, is this wiper ring the right size for it?
Answer by: Customer Support on Jun 17, 2025, 8:44 PM
The key number is the rod diameter. This AN style urethane wiper ring is sized for a 0.935 inch rod diameter (often rounded and spoken as 0.94), and it’s made to sit in a groove with about a 1.21 inch groove OD.
Question by: Phil H on May 9, 2025, 6:32 PM
does this wiper ring work down to pretty cold temps? got equipment that sits outside through winter and needs to hold up
Answer by: Customer Support on May 11, 2025, 7:36 AM
Urethane construction on this one handles a range from -65°F all the way up to 220°F, so cold weather storage and operation shouldn't be a problem. That lower end covers just about any outdoor winter condition you're likely to run into.
Question by: Ross A on Feb 1, 2026, 6:36 PM
Just want to make sure this is the right size for my cylinder... rod's about 0.94 inch in diameter.
Answer by: Customer Support on Feb 3, 2026, 6:09 AM
This wiper ring is designed to fit rods with a 0.94 inch diameter, and it needs a groove that's around 1.21 inches on the outer diameter.
