This nut is a critical component used within the air brake systems of commercial vehicles, specifically for fittings. Manufactured by Wabco under MPN 8935000044, this nut ensures secure connections within the air brake lines. It measures 7 x 4 x 14 mm and features a M12 x 1.5 thread and a 17.0 mm wrench size, meeting original equipment (OE) specifications. This nut provides a robust and reliable fastening solution, contributing to the safety and performance of the air brake system. This nut basically secures air brake lines and fittings together. It’s a pretty simple part, but it needs to create a really tight, air – tight seal. It’s threaded, of course, and you’ll tighten it down to clamp everything together. It holds the connection firm against the pressure of the air system. This nut is part of your air brake lines, which, naturally, control your brakes. Air brakes are used on larger vehicles—trucks, buses, trailers—and they're vital for stopping safely. This nut is a small component within that entire system, but it's located right at the connection points where air flows. You’ll find them connecting hoses to various components like air tanks, valves, and actuators. It's crucial because air brakes rely on completely sealed lines. Any leak, even a tiny one, reduces braking power and can be extremely dangerous. This nut acts like a shield, preventing air from escaping at a critical connection. You’ll notice if one of these is damaged or missing pretty quickly – you’ll likely have a brake warning light come on, or experience reduced braking performance. It might seem small, but losing air pressure because of a faulty nut can have serious consequences. We often have these in stock at Fixparts Online if you’re looking to replace one, and they're pretty straightforward to swap out, though proper torque is always important when working with air brake systems. Professional-grade support: Nut (MPN 8935000044) comes with a 12-month warranty!
