Hose Set

Created for continuous-duty rock drilling applications, the Hose Set (OEM 550 665 59) offers a service-focused replacement choice for the lubrication and service-fluid circuit. It routes and connects hydraulic fluid, water or air between components while helping maintain a secure, low-leakage interface.

Controlled mating surfaces help maintain a secure connection and reduce leakage risk in circuits exposed to vibration, pressure pulsation and field contamination. As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Typical listed applications include DX680 and DX700, subject to machine specification and configuration verification.

This component forms part of Delkom’s alternative spare-parts program for professional drilling machinery. For current stock, commercial terms and technical cross-checking, quote Delkom part number 110 500 147 with OEM reference 550 665 59.
