Lincoln 3034 Coupler Hose Assembly

The Lincoln 3034 is a twelve inch steel hose extension designed for hand operated grease guns. It features a 1/8 inch male NPT connection and includes a standard coupler and swivel assembly for button head fittings. The assembly is built from steel for durability in lubrication tasks. It carries a working pressure rating of 4000 psi.

Suits technicians needing extra reach on manual

This assembly suits technicians who need extra reach when servicing fittings with a hand operated grease gun. The twelve inch length and swivel action improve access in tight spots. It is not for buyers who need a longer reach beyond twelve inches or a different thread size than 1/8 inch MNPT. High volume automated systems require different equipment.

Handles 4000 psi working pressure

The hose handles a working pressure of 4000 psi with a minimum burst pressure of 12000 psi, providing a substantial safety margin for high pressure grease applications. The steel construction resists deformation under load. It runs out of reach at twelve inches, so deeper fittings need a longer extension or alternative access method.

Questions about this item

What grease gun fitting does the 1/8 in MNPT connection on this 12 in hose assembly thread into?

The 1/8 in MNPT end screws directly into the outlet port of any hand operated grease gun with a matching female thread.

Will the 4,000 psi working pressure of this assembly exceed the rating of an older Lincoln hand gun I already own?

Most legacy Lincoln hand guns are rated at or above 4,000 psi, so the assembly will operate within the gun's design limits.

How can I confirm the swivel and standard coupler on this 3034 assembly move freely after installation?

Pressurise the gun and rotate the hose; the swivel should turn without binding and the coupler should lock onto a grease fitting with a positive click.
