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

Header pipe retention spring

This is an RC-scale exhaust header pipe fixing spring engineered to hold an exhaust header against the pipe flange during assembly and setup. The spring functions as a retention clip so the header remains in place while you install, align, or evaluate exhaust positioning on nitro or tuned RC systems.

Fitting is simple: find the mating groove on the header or pipe, place the spring over the joint, compress it into the groove and verify the header is snug and stable without excessive play. Check the spring after several runs to confirm it keeps tension and has not distorted from heat or vibration.

For tuning and upkeep the spring provides basic mechanical retention, preserving exhaust alignment during runs and making repeated removal and refit faster when changing pipe length, manifold angle, or carrying out routine checks.
