Connex COX591300 lever gun with high-pressure hose review

A lever gun with a filling and bleed nipple — the fitting that lets you purge air after a cartridge change instead of pumping into nothing.

The last word The gun that solves the annoyance. A bleed nipple is worth more than a pressure figure.

What lands on the bench

A hand-lever grease gun with a high-pressure hose, an ergonomic handle and a combined filling and bleed nipple.

The feature that matters most

The bleed nipple. Nearly every “my grease gun doesn’t work” story is trapped air after a cartridge change, and a bleed point turns a ten-minute fight into a two-second purge.

What is not published

Pressure and cartridge size. Neither is the reason to buy this one, and both are worth confirming with the seller if they matter to you.

The upgrade that applies here too

A locking coupler. Every gun in this hub ships with a four-jaw coupler, and every one of them is better with a locking one.

On sale at around $81 on the American Amazon store at the time of checking.

Compromises

  • No pressure figure published
  • No cartridge size published
  • Lever design needs two hands

The questions that reach us

Why does a grease gun stop pumping?

Air. A cartridge change traps it, and a gun full of air compresses instead of delivering. A bleed nipple lets it out; without one you are pumping and loosening the head repeatedly.

What is a filling nipple for?

Refilling from bulk grease using a filler pump, which is cheaper per kilo than cartridges if you use a lot. For a household, the cartridge is simpler.
