Exhaust Header Retention Spring for RC - O.S. Engine OS72103220 15RX  [OS72103220]

Retention spring for exhaust headers

This component is an RC-scale exhaust header pipe fixing spring intended to retain the header to the pipe flange while you assemble and adjust the system. It acts as a clip to keep the header seated during installation, alignment, and initial testing on nitro or tuned RC rigs.

To fit, locate the groove on the header or pipe, slide the spring over the joint, compress it into the groove and make sure the header is correctly seated and free from significant play. Inspect the spring after a few runs to ensure it retains its shape and tension against heat and vibration.

During tuning and maintenance the spring's purpose is mechanical retention, making it easier to preserve exhaust position across runs and simplifying repeated removal and reattachment when changing pipe length or adjusting manifold angle.
