Often you can't get the standard grease gun clip-on adapter onto the unijoint zerks because of the angle of the yoke/spiders. With this tip you just push into the zerk end so it depresses the ball. That also centers the tip. Pump away, job done. No leakage around the tip - seals amazingly well with just reasonable pressure pushing the tip against/into the zerk end.Very impressed, kicking myself for not having bought one a few decades ago... Greasing all the unijoints now just takes a couple of minutes. Takes longer to get under the vehicle :)
