Are you struggling with your grease coupler when greasing your equipment?


With a G Coupler grease coupler, you won’t be struggling anymore.


 Here’s why …


The Alemite Zerk grease fitting nipple design revolutionised the chore of greasing joints.  Zerk compatible push-on, slotted and slide-on right angle grease coupler designs have been around for over 80 years.  This despite various weaknesses.

  • grease leaking out the sides of the coupler during greasing – leaving you wondering how much grease is going into the joint
  • the coupler detaching under pressure, forcing you to hold the coupler in place during greasing
  • the coupler locking onto the Zerk when back pressure remains in the delivery line, making it very difficult to remove
  • couplers typically have a short service life – they are regarded as a throw away consumable

It was time to take a fresh look at solving these problems. The result? G Coupler. A game changing, patented lock-on grease gun coupler that solves all the above problems – simply and elegantly.

See for yourself. No hands, no mess, no wasted grease!


Grease coupler clips easily onto the Zerk for hands-free operation

Activate Trigger to engage – Easy coupling

A patented lever action and sliding sleeve securely locks the G Coupler onto the Zerk, creating a leak proof seal. Grease is delivered into the joint. Hands-free greasing is now a reality.

Look, no hands – Easy greasing

See for yourself as the grease coupler is locked on and pumped to 690 bar (10,000 psi) – no hands needed to align the coupler or keep it on the Zerk nipple. No leaking grease.

Grease coupler attached to Zerk grease nipple and pumped to 690 bar (10,000 psi) - hands-free operation, no leaking grease

Leak proof greasing – even at extreme angles

The G Coupler grease coupler is locked on at 690 bar (10,000 psi) – it’s then forced to extreme angles on the Zerk grease nipple WITHOUT LEAKING.

Activate Trigger to disengage – Easy release

Simply pressing the trigger releases the grease coupler from the Zerk, NO MORE STUCK COUPLERS! No more broken fittings.

Grease coupler unclips easily off the Zerk regardless of pressure

Replace your existing coupler with a G Coupler and experience easy greasing. Compatible with most grease guns, including Lincoln, PowerLuber, Lumax, Alemite, DeWalt and Plews lubrication guns.

When a tool works well, you’ll use it. Leaking and stuck couplers, are the leading causes of greasing frustration and substandard machinery greasing maintenance. With the G Coupler grease coupler, the grease goes into the joint, not around the Zerk. When you use a G Coupler Grease Gun Coupler, your machines will be well greased, reducing wear and tear. All that for the price of a grease coupler. It’s a No Brainer.
