What is Viton material and why is it used for these O-rings?

Viton is a high-performance fluoroelastomer known for its exceptional resistance to high temperatures and aggressive fluids like engine oil. This makes it ideal for sealing applications within an engine where heat and oil exposure are constant.

How many O-rings are included in this pack?

This pack includes ten (10) O-rings. This provides enough for several service jobs or to keep spares on hand for future maintenance needs on your Harley-Davidson M8 motorcycle.

Do these O-rings come with any installation hardware?

This product includes only the Viton O-rings for the breather assembly. Any other necessary hardware or components for your specific motorcycle model would need to be sourced separately.

Product Details

This is a 10-pack of Viton O-rings from Cometic Gasket, specifically made for the breather assembly on Harley-Davidson Milwaukee 8 (M8) engines. These O-rings are crucial for maintaining a proper seal in your engine's crankcase ventilation system, helping to prevent oil leaks and ensure the engine breathes correctly.

Made from Viton, a high-performance fluoroelastomer, these O-rings offer excellent resistance to heat and oil, which is essential for the demanding environment inside an engine. This material choice means they hold up well over time, resisting degradation from engine heat and fluids. Having a 10-pack means you'll have spares on hand if you're working on multiple bikes or if one gets damaged during installation. They are designed to fit right into the stock breather assembly locations on a wide range of M8 Harley-Davidson models, including popular bikes like the Road King, Street Glide, and Fat Boy.

When you're rebuilding or servicing the top end of your Milwaukee 8 engine, ensuring all seals are in good condition is key to a reliable build. These Cometic O-rings are a well-built replacement part to help you get the job done right.
