Review on 🔧 Grease Gun Coupler - Performance Tool W54234 - Narrow Body by Richard Edwar

I have a 90 degree coupler to lubricate a boat gimbal bearing where the transom is interfering with the lubricator. The ferrule attaches so poorly to the grease gun fitting that the grease poured out of the nipple instead of being pushed through the ferrule and end - forget enough pressure to then squeeze the other zirconium fitting. I was able to disassemble the coupler and just attach the 90 fitting at the end to the threads on the end of the gun hose so no zircon joint was spewing grease, but the end fitting also didn't fit snugly into the zircon nipple on the boat. I used a lever to push the fitting onto the boat nipple while forcing the grease through and it worked but damn it. spent an hour doing a 30 second job. Look elsewhere for a 90 degree oiler.
