Ca Cycleworks Ducati Cam Cap Viton O-Ring (each)

*Price is per O-Ring*

This o-ring replaced Ducati OEM part number 886.4.001.1A and seals the cam end caps to the heads on desmoquattro models: 996, 916, 888, 851, 748, S4, ST4. Our Viton Fluoroelastomer O-Rings are best of practice recommended for use on engines and are rated to 400°F; further, these o-rings surface are more resistant to damage than standard BUNA / Nitrile o-rings. Removing the cam end cap on the belt side (with the cam) makes it a little easier to adjust the valves on these models. Some people remove all the cam end caps while other people only remove 4 for them and patiently feed the camshaft out of the right side of the engine.

In depth: These Viton o-rings chosen for the mil-spec suitability
for exposure to high temperatures. Your engine's cylinder
heads can operate as high as 380°F. Get o-rings designed
for the task.

Max. Continuous Service Temperature
Viton: 204°C / 399°F
Buna/Nitrile: 121°C / 250°F

Viton retains sealing force to prevent leaks even after
compression for long periods in severe environments.
After 100 hours in air at 150°C (302°F), Viton retains
more than 90% of its original sealing force, while
seals of nitrile retain 40%. Buna/Nitrile is the least
expensive most readily available material.
