Piston Cover

The Piston Cover (OEM 2635 8369 49) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. As the core driver of percussive energy, it converts hydraulic pressure into the high-impact blows that fracture rock, making its dimensional accuracy and surface integrity critical to drilling efficiency.

Manufactured from premium hardened steel with precision-ground striking and guide surfaces, it withstands extreme cyclic impact loads while maintaining tight running clearances for maximum impact energy transfer. As an alternative spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.

Delkom manufactures and exports premium alternative rock drilling, drifter equipment and spare parts to more than 100 countries. Contact us for current availability, bulk pricing and technical support.
