Westward 48UJ79 Grease Gun 5000 psi

The Westward 48UJ79 is a pistol-grip grease gun built for automotive, farm, construction, fleet and industrial maintenance. It accepts both 14 1/2 oz cartridges and 16 oz bulk loads for flexible resupply. The tool develops 5000 psi maximum operating pressure through a full-stroke mechanism. An 18 in flexible hose extends reach to tight fittings.

Loading method and hose benefit

Dual loading via cartridge or bulk lets technicians match the supply method to the job without a separate gun. The flexible hose reaches fittings that a rigid extension cannot, reducing the need to reposition heavy equipment. Full-stroke operation delivers a consistent 0.018 oz per stroke for predictable lubrication volume.

Capacity and pressure headroom

The 16 oz bulk reservoir and 14 1/2 oz cartridge capacity support extended service intervals on large fleets or heavy machinery. At 56.0 strokes per ounce, a full load provides hundreds of strokes before reloading. The 5000 psi rating handles high-pressure pins and bushings, though very low-temperature greases or extremely long hose runs may exceed practical flow limits.

Questions about this item

How often will the 18 in flex hose need to be replaced under normal use?

The 18 in flex hose is a wear item; replace it if cracks, stiffness or leaks appear, otherwise it lasts through many 14 1/2 oz cartridge changes.

What limits continuous operation at the 5000 psi rating?

The 56.0 strokes per ounce and full-stroke action mean hand fatigue and heat buildup in the aluminum tube become the practical limits during extended high-pressure use.

Does the pistol-grip grease gun get hot or noisy when used all day?

The metal tube warms up with sustained 5000 psi pumping, but the mechanical design produces only normal ratchet noise; no motor or hydraulic whine is present.
