When to Replace

Replace the 20K-22-11190 when you see any sign of fluid leakage at the sealed connection. Inspect the old O-ring when the joint is opened — hardening, cracking, or a permanent flat spot indicates it needed replacement. Cuts, nicks, or extrusion on the surface are clear evidence of damage. And never reuse an O-ring from a previously sealed joint — always install a new one.

Installation

1. Confirm 20K-22-11190 matches the old seal
2. Clean the groove — old fragments and debris cause leaks
3. Lubricate with clean hydraulic oil — helps the O-ring seat without rolling
4. Position without twisting — a rolled O-ring leaks under pressure
5. Tighten to the specified torque
