Overview – RUBBER HOSE C179940 Series
Built to Cummins specifications, the RUBBER HOSE C179940 serves Cummins hydraulic-line positions; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
A rubber hose that carries fluid between fixed points so the line stays flexible in the hydraulic supply, so the hose run stays soft and sealed. It carries the service life the hydraulic supply depends on, so a true, correctly specified unit keeps the age and split from the fluid weeps and the pressure falls.
Applicable Models & Applications
Used at Cummins Hydraulic Parts positions specifying this RUBBER HOSE. Match the bore, port and seal face against your old unit – Hydraulic Parts parts differ in how they seat and bolt.
Maintenance & Replacement
Inspect for wear and a loose fit at every service. A rubber hose that has begun to fail lets the hose run drift, and the drift is what causes the age and split.
Confirm the rubber hose seats and the fixings hold on fit. A unit canted in its bolts lets the hose run move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A rubber hose reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct rubber hose for your hydraulic parts on the bench. It is cheaper than the downstream failure, and it is exactly the part missing when a service needs doing today.
