Extended Grease Gun for Argo?

[pcmark]

ODG was thoughtful enough to add the holes in the Argo rims to grease the outer axle bearings without removing the wheels. In their promo video, they show a grease gun with about 16"-long rigid nozzle, which is really what's needed to pass through the depth of the rim to the bearing fitting. Does anyone have a link to where such a long grease gun can be ordered? Thank you.

Pcmark - all thats really needed is another section of rubber line for your grease gun. It gave me a 3 foot reach. At least thats how I've been doing it for the past 2 years

I just went to the hardware store and picked up two 6" copper nipples and two couplers, the same dia. as my grease gun, the threads are all the same, and just screwed it all together along with the extention that came with the gun.
