The SA4003 P15 ring is an aviation-grade precision ring component used in certified piston aircraft engine assemblies. It functions as a retention, spacing, sealing, or alignment element depending on the specific installation within the engine structure.

This component is engineered for use in Continental-compatible engine systems and is designed to maintain dimensional stability and reliable performance under continuous vibration, thermal cycling, and mechanical load conditions typical in aviation environments.

Key features include:

PMA-approved aircraft engine ring component
Precision-machined aviation-grade metal construction
Designed for retention, spacing, or sealing functions
Ensures stable alignment of engine components
High resistance to heat, vibration, and cyclic stress
Compatible with Continental piston engine applications (IPC/model dependent)
Used in engine internal, accessory, or structural assemblies
Suitable for certified aircraft maintenance and overhaul operations
Durable aviation metallurgy for long service life
Supports reliable engine rebuild, repair, and replacement procedures
