Its OE specification guarantees compatibility and performance consistent with original equipment standards, maximizing the longevity and reliability of the air brake system.

Key Features & Benefits

This nut does exactly what it sounds like – it secures air brake lines and fittings. Specifically, it's a nut with a nylon insert, sometimes called a ‘stover nut’ or ‘nylock nut’. That nylon piece is key. It basically deforms slightly when you tighten it, creating friction and gripping the bolt threads. It's designed to resist vibration. This is part of your air brake system, which obviously is critical for stopping. It connects sections of the air lines together, maybe at a brake chamber, the air dryer, or where the lines run to the valves. You’ll find these used all over the air system. They aren’t something that moves, they’re fasteners holding everything solid.

Symptoms, Risks & Replacements

Honestly, this is a safety item. Air brake systems rely on airtight connections. Regular nuts can loosen with the constant vibrations of driving, causing leaks. A leak, even a small one, can reduce your braking power and that’s, well, not good. This lock nut acts like a shield against loosening, keeping everything tightly sealed and your brakes working reliably. You’ll notice if you start losing air pressure, and often a leak will be the source, and sometimes it’s a loose fitting secured by something like this. We stock these at Fixparts Online, and it’s a good idea to replace them any time you disassemble an air line for maintenance, just to be safe.
