Product Description
The 753-189 is a bonded-seal washer combining an elastomeric seal element with a metal washer backing. This assembly creates a fluid-tight seal directly beneath bolt heads and fitting connections in aircraft hydraulic systems. The elastomer compresses under fastener torque to prevent leakage at component interfaces.
Installation requires positioning the seal washer under the fastener head and torquing per aircraft maintenance manual specifications. Verify part applicability in the Illustrated Parts Catalog before installation on hydraulic components.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
