Aftermarket 272394 Elbow Hose Stud
This page describes an aftermarket 90 degree elbow hose stud assembly that cross-references the Lincoln 272394. Lincoln is a trademark of its respective owner. This is an aftermarket fitting, not manufactured, sponsored, or endorsed by Lincoln. 272394 designations are for cross-reference identification only.
Quicklinc push-in style elbow for right-angle hose routes in confined spaces where a straight connector would kink or stress the hose. The assembly is used for centralized lubrication systems on manufacturing machinery, heavy equipment, mining, and vehicles.
Why a 90 Degree Elbow
A straight stud sends the hose directly outward. The elbow turns it immediately at the outlet. This design is used for tight spaces, side-entry routing, and preventing kinks when the line must change direction. The choice is routing, not lubrication function.

The Required Sleeve
The 272427 threaded sleeve is the companion component for the hose connection. Order the sleeve with the stud unless you already hold stock. Confirm hose ID matches 1/8 inch before ordering.
The sleeve grips the hose wall as the nut tightens, so a worn or cross-threaded sleeve is the most common cause of a weeping connection at service time. Keep a few spare sleeves on the maintenance shelf if you run many elbow routes, because the elbow body itself usually outlasts several sleeve changes. When ordering spares, match the sleeve to the same hose type used on the original assembly.
Installation
Depressurize the line. Fit the sleeve to the hose end. Push the hose onto the stud until it seats. Pull gently to confirm retention. Route the hose without going below its minimum bend radius. For related system service parts, see the Quicklub parts kit.
What to Confirm Before Ordering
Confirm hose is 1/8 inch ID. Confirm you need the 90 degree version rather than the straight 272401 stud. Confirm the 272427 sleeve is included or ordered. Confirm system pressure within 4,000 psi. For system planning, refer to progressive lubrication systems. If you are not sure which stud fits your line, contact the team.
