Wabco 8930500344 Cutting Ring 15mm DIN3861

Description

The Wabco 8930500344 Cutting Ring is a critical component used within air brake systems, specifically in fittings to create a secure and leak-proof connection between tubes. This 15mm DIN3861 cutting ring is designed for use with 15mm and 18mm tube diameters. Constructed to OE specification, this cutting ring ensures reliable performance and longevity within the air brake system, maintaining optimal braking efficiency and safety. It measures 10 x 4 x 18 mm.

Key Features & Benefits

This little ring is all about making a super reliable seal in air brake lines. It doesn't actually do anything mechanically, but it gets compressed when you tighten down the fitting, and that compression is what prevents air leaks. It's designed to bite into both the tube and the fitting itself, creating a really solid connection. It’s a pretty simple part, but it’s key to keeping everything airtight. Think of your air brake system like your circulatory system. You need pressure to travel consistently to the brakes to get them to work. This cutting ring is used in the connections between the air lines, the air dryer, the compressor, and ultimately, the brake chambers. Any leak, and you lose pressure, and that's a big problem. These rings are commonly found anywhere you have a flared tube connection in that air system.

Symptoms, Risks & Replacements

Well, air brakes rely on consistent pressure. If this ring fails, you’ll notice if you’re losing air pressure – maybe your brakes feel spongy, or you’ll hear a hissing sound. It acts like a shield against those leaks, so maintaining these connections is critical for safety. They’re cheap to replace, honestly, so it’s worth being proactive, especially during maintenance. We carry a good range of sizes here, and you can find these 15mm ones easily enough at Fixparts Online if you prefer to order that way. It’s just a small part, but a failure can cause a big issue down the line.
