I installed a set of Rough Country ball joints on a Jeep Wrangler and they came with low profile grease fittings so I needed the correct adapter for my grease gun. After some searching I read people recommended this Lincoln 5803 needle nozzle and found it for a good price under $10 with next day delivery.Installation was simple, just screwed right onto the end of my grease gun hose. I got under the car and pressed the tip of this needle nozzle into the fitting, you can feel it pressing the little ball valve in, then had a friend pump the grease gun until grease was coming out the bottom of the boots. Make sure you can feel the tip of the nozzle pressing the ball valve in or else grease will just leak out the sides and not go into the fitting. When it's seated right no grease leaks out.Works perfectly. Seems well made and should last along time. I'm not sure what the difference is between all the other needle nozzles I came across but glad I got this one since it seems like the perfect nozzle for the low profile fittings I have.
