Wabco 8931812144 M22 to 1/4" Reducing Adapter

Description

The Wabco 8931812144 Reducing Adaptor M22-R1/4 is a critical component used within air brake systems to connect components with differing thread sizes. Specifically, it adapts a M22 x 1.5 thread to a R1/4 thread. This adapter is commonly found in heavy-duty vehicles and trailers where air brake lines require secure and leak-proof connections. The adapter's OE specification ensures compatibility and reliable performance within the air brake system. It measures 20 x 27 x 29 mm and is a durable component engineered for consistent, dependable operation.

Key Features & Benefits

This little piece basically connects two different sized air brake lines together. You’ve got your larger M22 fitting, which is pretty standard on a lot of air reservoirs and some components, and it steps down to the smaller 1/4" size – that’s common for things like control valves and gauges. It’s a simple adapter, creating a secure, airtight seal between them. Think of it as a bridge. Your air brake system has different parts that need to “talk” to each other, and they don’t always use the same size connections. This adapter allows air pressure to flow smoothly between those different sized lines. It's usually found anywhere you see a connection point between a larger air storage component and the controls.

Symptoms, Risks & Replacements

It’s crucial because the air brake system needs to be completely sealed. Any leaks, even small ones, can reduce braking power and that's obviously dangerous. This adapter, when properly installed, acts like a shield against those leaks, ensuring that the pressure stays where it needs to be – building up for stopping power. You’ll notice if one of these fails – you might hear a hissing sound, or more seriously, experience reduced brake performance. We carry a lot of these at Fixparts Online, and it’s always good to have a spare on hand, especially if you’re doing any other brake system work. They’re small, inexpensive, and can save you a lot of trouble down the road.
