Product Questions & Answers (5)

Question by: Wes R on Mar 1, 2026, 8:59 PM
does this wiper ring fit a 2 inch rod or is that just the groove size
Answer by: Customer Support on Mar 3, 2026, 5:14 PM
The rod diameter on this one is 1.998 inches, so it fits a 2 inch rod. The groove OD comes in at 2.302 inches, which is the outer dimension of the groove it seats into. Two different measurements, both worth knowing before you order.
Question by: Bobby W on Jul 21, 2025, 5:11 PM
What material is this wiper ring made out of?
Answer by: Customer Support on Jul 22, 2025, 5:46 PM
These rings are made from urethane.
Question by: Dwayne R on Dec 8, 2025, 8:21 PM
got a cylinder with a 2 inch rod, is this wiper ring the right size or am i readin it wrong
Answer by: Customer Support on Dec 10, 2025, 6:09 AM
For sizing, it matches a 2.00 inch rod diameter, with the rod diameter called out at 1.998. The groove OD is listed as 2.30 inch, with a groove OD value of 2.302.
Question by: Brenda R on Apr 21, 2025, 4:05 PM
what's the rod diameter on this wiper ring, and will it fit a 2-inch rod on a hydraulic cylinder?
Answer by: Customer Support on Apr 23, 2025, 10:10 AM
The rod diameter on this AN-21 wiper ring is 1.998 inches, which is the standard tolerance for a 2.00 inch nominal rod. That fit is intentional. Wiper rings need a close but not binding fit against the rod to do their job, and that slight undersize keeps solid contact without drag that would cause premature wear.
Question by: Roy W on Apr 12, 2025, 1:54 PM
So this is a wiper ring, right? Just want to make sure it'll fit my 2 inch rod.
Answer by: Customer Support on Apr 14, 2025, 7:14 AM
Correct, this AN style urethane wiper ring is designed for a 2.00 inch rod diameter. The groove OD is 2.30 inches, and the groove width is also listed for proper fit.
