Got a small hydraulic cylinder that needs a rod seal, outside diameter on the rod housing is 0.563 in and the rod itself measures 0.3125 in. this seal gonna fit that setup?
Question by: Ray A on May 17, 2025, 8:04 PM
Those dimensions line up exactly with what this seal is built for. The 0.563 inch OD seats into the housing bore, the 0.3125 inch ID rides the rod, and the 0.25 inch height fits the groove depth for that configuration. The beveled lip design helps it break the fluid film cleanly across the rod surface, which keeps the seal working right without building up pressure behind it.

trying to match up a little u-seal, are these sizes the actual measurements or just a label?
Question by: Hugh A on Mar 26, 2026, 6:43 AM
For this one, the dimensions are given as actual sizes: 0.563 inch outside diameter, 0.3125 inch inside diameter, and 0.25 inch height. The cross section is 0.125 inch.

reckon this'll hold up alright in my hydraulic cylinder? i'm usin it pretty hard ya know
Question by: Joyce S on Jun 2, 2025, 10:30 AM
This U-seal is rated to handle pressures up to 6,000 PSI, so it should be suitable for demanding hydraulic applications. Its polyurethane construction also makes it durable over a temperature range of -65°F to 220°F.
