Lincoln 62028 Rigid Extension

The Lincoln 62028 is a 6 in rigid extension designed for hand operated grease guns. It connects via a 1/8 in MNPT fitting and suits maintenance tasks requiring a fixed reach. The steel construction provides durability for workshop or field use.

Sustained load behaviour

Heavy wall seamless steel tubing handles the working pressure of 3,000 psi during continuous greasing sessions. The tube resists deformation under steady force where thinner walls might flex. A minimum burst pressure of 14,000 psi adds a wide safety margin for prolonged use.

Interface practical limits

The 1/8 in MNPT thread limits compatibility to grease guns and fittings sharing that exact connection. It cannot mate with metric or larger NPT ports without an adapter. The 6 in length fixes the reach, so tasks needing shorter or longer access require a different extension.

Questions about this item

Will the 14,000 psi burst rating handle constant pressure from a hand grease gun all day?

The extension is rated for 3,000 psi working pressure with a 14,000 psi minimum burst pressure, so it handles continuous hand-gun operation within spec.

Does the 1/8 in MNPT connection fit my existing grease gun coupler directly?

The 1/8 in MNPT thread matches standard hand-operated grease gun outlets, so it threads onto the gun or coupler without adapters.

Can the 6 in steel tube reach fittings on older equipment with recessed zerks?

The 6 in length and rigid heavy-wall steel tubing extend reach for recessed or hard-to-access fittings on older machinery.
