KRETLAW mini grease gun kit, 3000 PSI review

A pistol-grip mini gun for 85 g (3 oz) cartridges: one-handed, small enough for a wheel arch, and supplied with three nozzles.

The last word One hand, small cartridge, three nozzles. The gun that actually gets used.

What lands on the bench

A pistol-grip mini grease gun in die-cast aluminum for 85 g (3 oz) cartridges, stated at 3000 PSI, with three nozzles.

Why one-handed matters

Because greasing usually happens somewhere your other hand is holding you up, holding a light, or holding a panel out of the way. A gun that needs two hands is a gun that waits for a better moment.

The cartridge trade

Eighty-five grams is a small amount of grease, and it is also grease that gets used before it separates. For a household with a handful of points, that is the better arrangement.

The pressure figure

3000 PSI, well below the lever guns. On a fitting that is already clear, it makes no difference; on a blocked one, a lever gun has more to give.

Availability

On sale at around $18 on the American Amazon store at the time of checking.

What it does, and what it misses

Strengths

  • One-handed operation, which is what a wheel arch or a tow hitch actually requires
  • Small cartridges mean grease that is still fresh when you use it
  • Three nozzles cover different fitting types

Compromises

  • 85 g (3 oz) runs out quickly on anything with several points
  • 3000 PSI is lower than the lever guns here, which matters on a blocked fitting
  • Small cartridges are less widely stocked than 400 g (14.1 oz) ones

The questions that reach us

Is a mini gun enough?

For hinges, latches, a tow hitch and a handful of nipples, comfortably. For a trailer with a dozen points, a 400 g (14.1 oz) lever gun is less work.

Does grease go off?

It separates over years, and a part-used 400 g (14.1 oz) cartridge that lives in a garage for a decade is not what it was. Small cartridges are used up while still fresh, which is a real if unglamorous advantage.
