Sealing O-ring 281808

Function & Role:

Part number  is a crucial sealing O-ring within gas engines. Its primary function is to create a static or dynamic seal, preventing leakage of fluids (such as coolant, oil, or fuel) and gases between two connected components. It ensures system integrity, maintains proper pressure, and prevents contamination, which is vital for the engine's efficient and reliable operation.

Usage & Application:

This specific O-ring is installed in a designated groove at a joint interface, such as between a housing and a cover, or on a shaft. Correct usage requires:

Ensuring the mating surfaces and the O-ring groove are clean and undamaged.

Applying appropriate lubrication compatible with the surrounding media before installation.

Carefully placing the O-ring into its groove without twisting or stretching it excessively.

Reassembling the components evenly to avoid pinching or cutting the seal.

Key Features:

Material: Typically made from a synthetic rubber compound (like FKM/Viton) resistant to high temperatures, engine oils, and coolants.

Reliability: Provides a durable and flexible seal under engine operating conditions.

Maintenance: It is a consumable part replaced during scheduled maintenance or component overhauls to prevent failures.

In summary, O-ring 281808 is a small but essential sealing component that safeguards the engine's performance by effectively containing critical fluids and gases. Its proper installation and timely replacement are fundamental maintenance practices.
