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

Fixing spring for header pipes

This part is an RC-scale exhaust header pipe fixing spring designed to hold the exhaust header at the pipe flange during assembly and setup. It serves as a retention clip to keep the header in position while you fit, adjust, or inspect exhaust alignment on nitro or tuned RC vehicles.

To fit the spring, locate the mating groove on your header or pipe, place the spring over the joint, compress into the groove and confirm the header is seated and constrained without excessive movement. Periodically inspect the spring after several runs to ensure it preserves tension and has not been altered by heat or vibration.

In routine maintenance and tuning the spring provides mechanical retention that helps keep exhaust positioning stable during operation and makes repeated removal and refit quicker when changing pipe length or manifold angle.
