Aftermarket 272401 Straight Hose Stud
This page describes an aftermarket straight hose stud that cross-references the Lincoln 272401. Lincoln is a trademark of its respective owner. This is an aftermarket fitting, not manufactured, sponsored, or endorsed by Lincoln. 272401 designations are for cross-reference identification only. The Quick-Connect straight stud connects high-pressure lubricant delivery hoses to system fittings in Lincoln Quicklub centralized lubrication systems.
Straight Versus Elbow
The straight stud sends the hose directly outward from the outlet. Use it where the hose can run without a sharp bend. For tight turns and side entry, the 90 degree 272394 elbow stud is the alternative. The choice is routing only. See the 272394 elbow hose stud for angled connections.

Where Straight Studs Fit
Main lubrication line connections to distribution blocks are a common placement. Heavy equipment where vibration and dirt threaten connections benefits from this stud. Automated factory lubrication lines use straight studs on direct hose runs. The positive-lock Quick-Connect design holds under machine vibration.
On a typical install, straight studs carry the long open runs along a machine frame where the hose can travel without changing direction, while elbow studs handle the corners and tight terminations. Planning the route this way keeps each hose in its natural line and avoids forcing a bend at the fitting. Check the whole run annually for rub marks near clamps and panel edges, and replace any stud whose locking collar feels loose before the connection works free under vibration.
Installation
Depressurize the line before starting. Confirm the hose end is cut square. Insert the stud assembly. Confirm the positive lock engages. Pull-test the connection after assembly. Route the hose with support clips so vibration does not work the connection loose. A Quicklub parts kit can supply related hardware for these steps.
What to Confirm Before Ordering
Confirm the hose is 1/4 inch ID, which is different from the 1/8 inch elbow stud hose. Confirm whether you need straight or elbow routing. Confirm the system pressure stays within 5,000 psi. Confirm the sleeve hardware for your hose end. If any detail is unclear, contact the team before placing an order.
