Diaphragm

The Diaphragm (OEM 040212-020321) is a high-quality alternative spare part built for rock drills and drifter rigs working under the toughest mining and tunnelling conditions. It is a precision internal component of the percussion or valve mechanism, governing the controlled movement and energy transfer that drive drilling performance.

Manufactured from hardened, precision-ground alloy steel, it withstands high cyclic impact and pressure loads while maintaining tight clearances and accurate operation. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.
