What's the temp range on this wiper? Just wanna make sure it'll hold up in my shop.

Question by: Steve J on Jul 17, 2025, 9:44 PM

Rated to handle temperatures from -65°F up to 220°F, this urethane wiper ring should do the trick.

Does this wiper ring fit a 1.25 inch rod, or is that just the nominal size? Want to make sure before I order.

Question by: Earl B on Sep 12, 2025, 11:01 AM

The rod diameter on this one is listed at 1.248 inches, so it's sized for what's commonly called a 1.25 inch rod. That slight undersize is normal for wiper rings since they need to contact the rod snugly to do their job. The groove OD comes in at 1.522 inches, so double-check your housing dimensions before dropping this in.

got a cylinder with a 1.25 rod, is this AN-13 wiper the right size or am i off a bit

Question by: Rick C on Jul 16, 2025, 3:36 PM

Fit comes down to the rod and groove numbers. This AN style urethane wiper ring is for a 1.248 inch rod diameter and a 1.522 inch groove OD, so it matches the common 1.25 inch rod callout when the hardware is built around those dimensions.

What size rod does this wiper ring fit? I wanna make sure I'm gettin' the right one.

Question by: Jerry T on Oct 8, 2025, 4:46 PM

It's made for rods that are 1.25 inches in diameter. To be exact, the rod diameter is 1.248 inches.

Answer by: Customer Support on Oct 10, 2025, 6:32 AM

Got a 1-1/4 inch rod on a cylinder that needs a new wiper. This the right part for that?

Question by: Donna R on Aug 9, 2025, 7:32 AM

that rod diameter lines up exactly. The AN-13 is built for a 1.248 inch rod diameter, so a standard 1-1/4 inch rod is what it's made to fit. Groove OD comes in at 1.522 inches, so just confirm your groove dimensions match up before you order and you should be good to go.
