Westward

Westward 4BY75 Manual Grease Gun 14 1/2 oz Cartridge 6000 psi

SKU CH-TB83-D27MX

Delivers lubricant up to 6000 psi with a 14 1/2 oz cartridge and 18 in flex hose

  • Delivers up to 6000 psi for heavy-duty lubrication tasks
  • Holds 14 1/2 oz cartridge or 16 oz bulk grease for extended use
  • 18 in flex hose reaches tight fittings with ease
  • Variable stroke design gives 40 strokes per ounce for controlled output
  • Pistol-grip handle with Feather Touch design reduces hand fatigue

What it is and who it's for

The Westward 4BY75 is a manual grease gun built for technicians and maintenance crews who need reliable lubrication delivery. It accepts a 14 1/2 oz cartridge or 16 oz of bulk grease. The pistol-grip handle and feather-touch design reduce hand fatigue during repetitive tasks.

When the upgrade makes sense

This tool replaces older guns that lack variable-stroke control or flexible hose reach. The 40 strokes-per-ounce rate and 6,000 psi maximum pressure suit heavy-duty fittings where high force is required. Buyers needing powered operation or larger reservoir capacity will not find those features here.

How it fits the workshop

The 18-inch flex hose and included filler nipple connect directly to standard grease fittings. Steel tube construction withstands shop abuse. A tether accessory is required for drop-prevention programs. No external power source is needed, freeasing up compressors or batteries for other equipment.

Questions about this item

What cartridge size fits the 14 1/2 oz capacity?

It accepts standard 14 1/2 oz grease cartridges and can also hold 16 oz of bulk grease.

How do you prime the gun after loading a cartridge, and what step is often missed?

After inserting the cartridge, pull the follower rod back, lock it, remove the cap, thread the barrel on, then pump the handle until grease appears — skipping the bleed step leaves an air pocket.

When should the 18 in flex hose be replaced?

Replace the hose if it shows cracks, leaks at the fittings, or becomes stiff — typically after heavy use or exposure to extreme temperatures.
