Overview – NIPPLE, HOSE 4096039 Series
The Cummins NIPPLE, HOSE 4096039 fits Cummins hydraulic and coolant hose routing on construction, industrial and generator engines; because multiple part numbers interchange, we list the related series so you can match what is on your machine.
Parts Characteristics
A hose nipple fitting with a threaded body on one end and a barbed tail on the other, used to terminate a rigid line into a flexible hydraulic or coolant hose. The threads seal the fitting into the manifold or component, while the barb locks the hose onto the tail with a clamp so system pressure cannot blow the line off.
Applicable Models & Applications
Fitted across Cummins hydraulic and coolant line arrangements wherever a hose meets a threaded port of this size and thread form. Confirm thread size, barb diameter and seat type against your parts book or the old fitting before ordering – a nipple that looks identical on the bench can carry a different thread pitch.
Maintenance & Replacement
Inspect every nipple at each service for hairline cracks at the thread root and a damp film where the hose clamps to the barb. A weep at that junction is the most common hose fitting leak, and it grows into a pressure loss long before it becomes a puddle.
Always fit a fresh hose clamp when the line is disturbed, and seat the hose fully onto the barb before tightening. A clamp pinching a hose that has not bottomed out on the barb will hold for a week and then walk off under pressure – usually on the far side of the site.
Match the new nipple to the old one by thread and seat, not by eye. Mixing a tapered-thread and a straight-thread nipple in the same port destroys both the fitting and the casting boss, turning a consumable into a machining repair.
Keep a small stock of the common nipple sizes for your fleet. They are cheap, they fail without warning when old, and a machine down waiting on a two-dollar fitting is a machine that should have been on the job.
