Lincoln Electric 71512 Hose Extension 12 Inches

Product Description

The LINCOLN ELECTRIC 71512 is a 12-inch flexible hose extension designed for use with manually operated grease guns. It connects grease guns to fittings in tight or awkward spaces where a rigid zerk fitting or short coupler cannot reach. The extension is constructed from steel and thermoplastic, with 1/8-inch MNPT connections on both ends. It carries a maximum working pressure of 3,000 psi and a minimum burst pressure of 12,000 psi, making it suitable for demanding lubrication tasks on industrial and commercial equipment. Licensed lubrication technicians and general maintenance mechanics are the primary installers.

This hose extension is intended for manual grease gun applications in residential, commercial, and light industrial maintenance settings. It is commonly used when lubricating chassis fittings, bearings, or other grease points on machinery, vehicles, and HVAC equipment where direct gun-to-fitting access is limited. The flexible thermoplastic hose body allows the technician to route the extension around obstacles without kinking or restricting grease flow.

Key Features

• 12-inch overall length provides reach into confined lubrication points
• Flexible thermoplastic hose construction resists kinking during use
• Steel-reinforced body supports 3,000 psi maximum working pressure
• Minimum burst pressure of 12,000 psi for a wide safety margin
• 1/8-inch MNPT connections on both ends for standard grease gun compatibility
• Packaged for retail and trade distribution

Compatibility

Designed for use with manually operated grease guns equipped with 1/8-inch NPT thread connections.

Installation Notes

Installation requires no special tools beyond a wrench to snug the NPT threaded connections. Before attaching or removing the extension, relieve any residual pressure in the grease gun by backing off the follower rod. Do not exceed the rated working pressure of 3,000 psi. Inspect the hose body and fittings for cracks or thread damage before each use and replace if any damage is found.
