Mini grease gun for 3 oz cartridges

The Westward 4BY82 is a pistol-grip grease gun built around a 3 oz cartridge. It delivers up to 4500 psi maximum operating pressure through a rigid 4 in steel pipe extension with coupler included. The tool measures 10 in overall and uses a full-stroke mechanism requiring 67 strokes per ounce of grease.

Sustained output with full-stroke action

Each full stroke displaces a fixed volume, so pressure builds steadily as long as the operator can maintain the pumping rhythm. The 67 strokes per ounce rate means a full 3 oz cartridge requires roughly two hundred strokes to empty, giving consistent delivery across the whole load without the drop-off seen in variable-stroke designs.

Heat, noise and power in normal use

As a purely manual tool it generates no motor heat, no electrical draw and no audible noise beyond the mechanical click of the stroke. The steel tube and rigid pipe withstand the 4500 psi rating without deformation, and the standard tether point allows secure attachment when working at height or in confined spaces.

Questions about this item

How much force does the 4500 psi rating generate during continuous use?

The gun delivers up to 4500 psi maximum operating pressure; each ounce of grease requires 67 full strokes so sustained use will demand steady hand effort.

What grease supply must I have on hand before the gun will work?

It accepts a standard 3 oz cartridge or up to 4 oz of bulk grease; no cartridge is included so you must provide one.

Will the 4 in rigid pipe and coupler reach fittings on my older equipment?

The 4 in steel extension with coupler fits standard grease zerks; overall tool length is 10 in so access depends on your machine's fitting placement.
