Description

Supporting maintenance teams working in abrasive, vibration-intensive environments, the Hose Reel Assy (OEM 551 549 78) is used in the hose routing and fluid connection system. Its role is to maintain a reliable connection in the fluid or air path, helping preserve flow while reducing the risk of leakage at the interface.

As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Accurate threads, mating faces and sealing points support dependable flow transfer while resisting loosening, leakage and misalignment under machine vibration. Cross-reference data lists applications including DD311-40 and DD320-40; final fit should be confirmed against the machine configuration or serial information.

Offered within Delkom’s aftermarket range for surface and underground drilling machinery, this part supports planned maintenance and international spare-parts supply. To confirm availability and fitment, reference Delkom 110 800 395 and OEM 551 549 78 when contacting the Delkom team.
