Insulating Tube

Designed to support reliable field operation and planned overhauls, the Insulating Tube (OEM 550 528 01) provides an aftermarket solution for the rock drilling machine assembly. The component provides a defined flow path and connection point, supporting correct routing and sealed transfer of the working medium.

The connection geometry is intended to preserve the flow path and sealing contact during pressure changes, servicing and repeated machine movement. As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Compatibility records include DD320-40 and DD321-40. For best results, check the part reference together with the machine model and serial data.
