  • Clears blocked fittings with up to 13,775 psi burst pressure
  • Handles heavy-duty jobs at 5,800 psi working pressure
  • Compatible with SAE 30 or higher oil for versatile use
  • Connects via 1/8 in MNPT for standard tool fit
  • Includes two spare seals and high-pressure hose with coupler

Grease Fitting Unblocker

The Westward 3APF6 clears blocked grease fittings using high-pressure oil. It suits maintenance crews and plant technicians who need to restore lubrication points without dismantling equipment. The tool connects directly to a standard grease gun hose and coupler. Two spare seals are included for quick on-site replacement.

1/8 in MNPT Connection Limits

The 1/8 in MNPT inlet accepts common grease-gun fittings and the supplied high-pressure hose. Working pressure is rated at 5,800 psi, so the tool must not be driven beyond that figure. Minimum burst pressure stands at 13,775 psi, defining the absolute safety ceiling. Only SAE 30 or higher viscosity oil should be used to maintain seal integrity.

Capacity and Headroom

The unblocker delivers enough force to free stubborn fittings in heavy machinery and fleet applications. It reaches its practical limit when a blockage requires pressure above the 5,800 psi working rating. Extremely hardened deposits or seized joints may exceed the tool's capability. For those cases, a higher-rated hydraulic solution is necessary.

Questions about this item

Should I pick the 5,800 psi working pressure or the 13,775 psi burst rating for my shop jobs?

The 5,800 psi working pressure is the limit for daily use; the 13,775 psi burst figure is a safety margin, not an operating target.

What does the 5,800 psi working pressure actually deliver when I connect it to a grease gun?

It pushes SAE 30 or heavier oil through a blocked 1/8 in MNPT fitting with enough force to clear hardened grease without exceeding the tool's rated limit.

How does the 1/8 in MNPT connection affect the pressure I can apply?

The 1/8 in MNPT thread mates with standard grease-gun couplers, letting the unblocker transmit the full 5,800 psi working pressure to the fitting.
