LINER (P/N 9543688) - New Surplus

The 9543688 is a PTFE-lined hose liner that maintains smooth internal bore in aircraft hydraulic assemblies. This internal sleeve reduces friction and wear during fluid circulation, protecting against abrasion in high-pressure lines. Built to SAE AS1339 specifications, the liner installs within hose or tubing runs per aircraft maintenance manual requirements.

Used in hydraulic systems where internal wear protection is critical. Route and secure per the Illustrated Parts Catalog and FAA AC 43.13-1B guidance.
