Extension Tube

The Extension Tube (OEM 3128 3125 79) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. It conveys pressurised fluid or air between components, forming a rigid, sealed flow path in the hydraulic or pneumatic circuit.

Made from high-strength, corrosion-resistant material to precise tolerances, it endures high working pressure and vibration for long, leak-free operation. As a cost-effective alternative component, it matches the form, fit and function of the original while maintaining high reliability.

Delkom manufactures the world’s highest-quality alternative rock drilling, drifter equipment and spare parts, exported to more than 100 countries. Contact us for availability, bulk pricing and technical support.
