The Multiquip CD2900412 Diaphragm Lock Washer M8 is a genuine OEM component designed for the DM15A9C Drill Rig Stand and CDM2CSA Core Drills. As an authentic Multiquip OEM part, it is manufactured to the exact specifications required for proper diaphragm retention and secure fastening in these units. Confirm your model against the DM15A9C and CDM2CSA fitment before ordering to ensure a correct, direct match.

Key Features

  • Genuine OEM Specification — Manufactured to Multiquip's exact dimensional and material standards for M8 locking hardware, ensuring correct torque retention and diaphragm clamping force.
  • Direct Drop-In Replacement — Engineered to seat correctly against the diaphragm surface with no rework or fitting required during reassembly.
  • Confirmed Fitment — Compatible with the DM15A9C Drill Rig Stand and CDM2CSA Core Drills; verify your model code before ordering.
  • Secure Fastening Under Load — The lock washer design resists loosening caused by vibration during drilling operations, maintaining consistent clamp load on the diaphragm assembly.
  • Fuel System Integrity — A properly functioning diaphragm lock washer prevents unwanted movement or leakage at the diaphragm joint, protecting system pressure and operational consistency.

The diaphragm lock washer serves as the fastening element that clamps and secures the diaphragm within the assembly, preventing movement, misalignment, or fluid bypass under operating pressure and vibration. Without a correctly seated and fully functional lock washer, the diaphragm can shift or lose its seal, leading to pressure loss, fluid leakage, or inconsistent system performance. Replacing a worn or damaged lock washer promptly restores proper diaphragm retention and protects the surrounding components from accelerated wear.
