O.S. Engine OS72103220 Exhaust Header Pipe Fixing Spring 15RX  [OS72103220]

Exhaust header pipe fixing spring

This is an RC-scale exhaust header pipe fixing spring designed to retain an exhaust header to the pipe flange during assembly and setup. The component acts as a retention clip to hold the header in place while you install, adjust, or test the exhaust alignment on nitro or tuned RC setups.

Installation is straightforward: locate the mating groove on the header or pipe, position the spring over the joint, compress into place and confirm the header is seated and held without excessive play. Inspect the spring after a few runs to ensure it maintains tension and has not deformed from heat cycles or vibration.

In tuning and maintenance workflows the spring’s role is purely mechanical retention, helping preserve exhaust position during runs and making repeated removal and reassembly easier when adjusting pipe length, manifold angle, or performing routine checks.
