Plug Washer
Bendix

Sealing washer used in sealing interfaces for systems with hydraulic or pneumatic control. This sealing element protects ports and joints from leakage while permitting easy reassembly during maintenance. It is designed to withstand pressure cycles and resist extrusion over time, contributing to long service life in brake control modules and auxiliary circuits. VMRS 053-007-008 classifies it within the same family as other fastener hardware components, while category 42848 anchors its place in brake and wheel end hardware. Compatibility with standard thread features and mounting configurations makes it suitable for both service and replacement in field operations. The device ships in quantities appropriate for multi unit service and reduces downtime by allowing rapid resealing during bleed and calibration tasks. Visual inspection and correct seating help ensure a reliable seal after torque is applied, maintaining system performance through multiple cycles of operation.
