Description & Features

Manufactured by Hercules Sealing Products, this AN Style Urethane Wiper Ring, 1.12 Inch Rod Diameter, 1.40 Inch Groove OD is designed to exclude contaminants from hydraulic cylinder rod assemblies, helping maintain seal integrity over extended service cycles.

Product Questions & Answers (3)

Question by: Donna S on Aug 10, 2025, 7:44 AM
got a cylinder with a 1.123 rod, is this AN-11 wiper the right size or am i off a hair
Answer by: Customer Support on Aug 11, 2025, 4:21 PM
Fit comes down to the rod diameter and the groove outside diameter. This AN-11 is sized for a 1.123 inch rod and a 1.397 inch groove OD, so it matches those dimensions for an AN-style groove.
Question by: Roy R on Nov 14, 2025, 7:33 AM
What exactly does this wiper ring do in a hydraulic cylinder setup, and is urethane a good material for that job?
Answer by: Customer Support on Nov 15, 2025, 12:25 PM
Wiper rings sit at the outer end of a hydraulic cylinder rod assembly and keep dirt, dust, and debris from getting past the seal area as the rod strokes in and out. Urethane holds up well in that role because it resists abrasion and maintains its shape under repeated mechanical contact. The temperature window on this one runs from -65°F all the way up to 220°F, so it covers most industrial hydraulic environments without any real concern about the material breaking down at either extreme.
Question by: Steve P on Jun 11, 2025, 12:36 PM
What size groove does this wiper ring fit into? I wanna make sure it's the right one for my cylinder.
Answer by: Customer Support on Jun 13, 2025, 10:25 AM
The groove OD (outer diameter) is 1.397 inches, and it's designed for a standard AN-profile groove. The rod diameter it fits is 1.123 inches.
