Wabco 4519999990 Sealing Roll

Description

This Wabco sealing roll, MPN 45199990, is designed for use in air reservoir systems within air brake systems. It provides a critical barrier against air leaks, ensuring optimal braking performance and system reliability. This roll measures 35 x 500 x 500 mm and meets OE specifications for a precise fit and dependable operation.

Key Features & Benefits

This roll is basically a long strip of rubber, and its job is to create an airtight seal between different sections of your air reservoir. Air reservoirs hold the compressed air that your brakes need to work, so this roll seals up any gaps where air could leak out. It’s not a complicated part, but it’s crucial. It comes in a long roll because reservoirs come in different sizes, and you'll cut the length you need for your specific tank. Think of your air reservoir as a big tank holding the air pressure for your air brakes. This sealing roll sits where the different sections of that tank join together. It prevents air from escaping when the compressor builds up pressure, and it keeps moisture out too. It’s a key part of the whole air brake system, a lot like how a seal on a jar keeps everything inside fresh.

Symptoms, Risks & Replacements

Well, if this roll fails, you'll start losing air pressure. You’ll notice if your air brakes aren’t holding like they should – you might have to pump the pedal more often, or the brakes might drag. A continuous leak can eventually mean your brakes just won’t work reliably, which is obviously a big safety issue. It's a relatively inexpensive part to replace compared to dealing with brake failures or more extensive air system repairs. We carry a good selection of these at Fixparts Online, and it’s one of those things that’s good to check during routine maintenance before a small leak turns into a bigger problem.
