Designed for use in hydraulic cylinders, this nylon wear ring from Hercules Sealing Products provides lateral support and guides the piston or rod to prevent metal-to-metal contact during stroke. With a 3.5-inch OD, 1/8-inch thickness, and 1/2-inch width, it fits standard bore configurations where controlled clearance and low friction are priorities.
The Nylon Wear Ring, 3.50 Inch OD, 1/8 Inch Thick, 1/2 Inch Width is rated for a compressive strength of 35,000 PSI and a tensile strength of 27,000 PSI, with an operating temperature range of -40°F to 250°F. These properties make it suitable for demanding hydraulic applications where wear resistance and dimensional stability under load are required.

Product Questions & Answers (4)
Question by: Harold G on Mar 21, 2026, 2:56 PM
Is this wear ring actually nylon? I need something that can handle some serious pressure.
Answer by: Customer Support on Mar 23, 2026, 8:10 AM
Yes, this wear ring is made from nylon. The nylon material is rated to handle compressive strength up to 35,000 PSI.
Question by: Ricky J on Jun 21, 2025, 6:08 PM
what temperature range is this wear ring rated for? got a cylinder that sees some pretty cold mornings and hot afternoons and just want to make sure it'll hold up
Answer by: Customer Support on Jun 23, 2025, 1:17 PM
Rated from -40°F up to 250°F, so it handles a wide swing between cold starts and heat buildup without issue. Most outdoor hydraulic applications fall well within that range, even in conditions that see hard freezes or summer heat loading on equipment that runs most of the day.
Question by: Gene L on Aug 24, 2025, 7:24 PM
What's this nylon ring used for?
Answer by: Customer Support on Aug 26, 2025, 2:17 PM
It's used as a wear ring in hydraulic applications. It helps guide the piston or rod and prevent metal-to-metal contact.
Question by: Johnny H on Feb 23, 2026, 8:52 PM
trying to match up a wear ring i pulled out, are these dimensions 3.50 OD, 1/8 thick, and 1/2 wide?
Answer by: Customer Support on Feb 25, 2026, 1:39 PM
The key callouts on this ring are a 3.5 inch outside diameter, 1/8 inch thickness, and 1/2 inch width, so it matches those three measurements exactly.
