Westward 4BY72 Lever Grease Gun

The Westward 4BY72 is a lever-action grease gun built for automotive and industrial maintenance. It accepts a 14 1/2 oz cartridge or 16 oz of bulk grease, giving technicians flexible loading options. Variable-stroke operation lets the user adjust output per stroke for precise lubrication. A non-slip textured powder-coated barrel improves grip during extended use.

10000 psi Operating Pressure with 18 in Flex Hose

The gun delivers a maximum operating pressure of 10000 psi, suitable for high-pressure greasing tasks. An 18 in flexible hose extends reach to fittings in tight or awkward locations. Each ounce of grease requires 31.0 strokes, so high-volume jobs demand more cycles. The standard tool tether style requires an accessory for secure tethering.

Upgrades from Fixed-Stroke or Lower-Pressure Models

This unit replaces fixed-stroke guns that lack variable output control. The jump is worth it when technicians need adjustable delivery and 10000 psi capability for demanding fittings. It is not for buyers who need a pistol-grip or battery-powered design for one-handed operation. It is not for users who require a built-in tether point without adding an accessory.

Questions about this item

How do I choose between the 14 1/2 oz cartridge and the 16 oz bulk loading option?

Use the 14 1/2 oz cartridge for quick, mess-free reloads or switch to 16 oz bulk fill when you have a filler pump and want fewer refills on big jobs.

What does the 10000 psi rating mean when I'm actually greasing a fitting?

It delivers enough force to push grease through tight or clogged fittings on heavy equipment without the gun stalling or leaking back.

How does the 18 in flex hose affect reach and pressure at the fitting?

The 18 in steel-braided hose lets you reach awkward zerks while still transmitting the full 10000 psi from the variable-stroke lever.
