Hydraulic Cylinder Seal Rings - MOB and HOB Options
Choose a seal option by the complete MOB or HOB cylinder model and the dimensions of the existing parts. Confirm the seal profile, material and required quantities before selection.

MOB63 component reference
The MOB63 reference records specifications and quantities from the supplier source. Units are not printed in that source; confirm the units, seal dimensions and fit against the existing parts before use.
Shared supplier illustration
For the MOB80, HOB50 and HOB150 seal options, this photograph is a shared supplier illustration of seal-ring shapes and arrangement. It does not specify the dimensions, material, quantities or complete contents supplied for a selected option. Before ordering, confirm the cylinder model, piston/rod and seal-groove dimensions, each seal profile and size, material and the required quantities against the existing parts or an approved specification. The source parameter combinations for these three options still require confirmation.
