Description & Features

Manufactured by Hercules Sealing Products, this AN Style Urethane Wiper Ring is designed for use with a 0.873-inch rod diameter and seats into a groove with a 1.147-inch outside diameter. The urethane construction provides reliable performance across a temperature range of -65°F to 220°F, making it suitable for a broad range of hydraulic cylinder and linear actuator applications.

Available in variant configurations: the SH suffix designates a slotted heel design, the V suffix indicates fluorocarbon material, and the B suffix designates carboxylated nitrile material. Wiper rings of this style function to exclude contaminants from the rod as it retracts, helping to maintain seal integrity in demanding hydraulic service environments.

Product Questions & Answers (3)

Question by: Norm R on Jul 4, 2025, 4:30 PM
What size rod does this wiper ring fit? Gotta make sure I get the right one.
Answer by: Customer Support on Jul 6, 2025, 12:33 PM
This Hercules wiper ring is designed to fit rods with a 0.873-inch diameter. It's made to seat into a groove with a 1.147-inch outside diameter, so double-check those measurements before you order.
Question by: Phil M on Nov 11, 2025, 3:28 PM
got a cylinder rod that measures 0.873, is this the right wiper ring for it?
Answer by: Customer Support on Nov 13, 2025, 6:00 AM
The key numbers line up like this: it is made for a 0.873 inch rod diameter and it seats in a groove with a 1.147 inch outside diameter.
Question by: Ray M on Jun 11, 2025, 11:14 AM
Got a cylinder rod measuring .873 inches across, will this wiper ring seat right into the groove without needing any modification?
Answer by: Customer Support on Jun 13, 2025, 7:55 AM
For a rod at exactly 0.873 inches, this is the correct fit. The groove it seats into runs 1.147 inches on the outside diameter, so as long as your hardware matches those dimensions, you should be good to go right out of the bag. No modifications needed when the measurements line up like that.
