Key Features & Benefits

These are basically little nozzles where you inject grease into a part. They have a small head, and a passageway inside where a grease gun nozzle fits right on. You pump grease through it, and it gets delivered to where it needs to go – usually ball joints, tie rod ends, universal joints, and other moving parts. Some are straight, some are at a 90 – degree angle, depending on where you need to reach. Think of these as access points for lubrication. Many parts need regular greasing to keep things moving smoothly and prevent wear. Instead of taking the whole thing apart to grease it, the fitting gives you a direct route. In air brake systems specifically, they’re often on slack adjusters, letting you keep the S – cam mechanisms properly lubricated. They’re pretty small, but essential.

Symptoms, Risks & Replacements

Without these, metal rubs on metal. Plain and simple. Grease acts like a shield, reducing friction, preventing rust, and ultimately extending the life of those parts. If a fitting is missing, damaged, or clogged, you’ll notice if you try to grease the component – the grease will just squirt out around it. If you ignore it, things will start binding up, wearing out faster, and could eventually lead to a breakdown. You can find a good selection of these at places like Fixparts Online, and they’re pretty straightforward to replace if one’s bad. It’s a small preventative maintenance item that can save you a lot of money down the road.
