Hydraulic rod seals
A rod seal sits in the cylinder head (gland) and closes on the moving chrome rod. It holds rod-side pressure so oil does not run out along the rod as the cylinder strokes.
Open a series below for the live ID, OD and H table, or search a measured size such as 36x44. Dimensions appear only when they exist on the product record — we do not invent missing sizes.
How to specify
- Inner diameter / rod (ID, d)
- Outer diameter / gland (OD, D)
- Section height (H, L)
- Series code, or a photo or drawing if the profile is unknown
