Threaded M14 header nut for FS120 models

This M14 exhaust header pipe nut is an RC accessory made to lock the junction between an exhaust header and the muffler on O.S. Engine FS120-series nitro powerplants. It serves the mechanical purpose of clamping and sealing the joint to cut exhaust leaks and help sustain correct backpressure during setup.

Fitting is straightforward: hand-start the nut on the header stub, align the pipe, then tighten progressively to avoid cross-threading. Follow accepted RC workshop guidelines for torque and thread engagement, and confirm there are no exhaust leaks after the first short run. The text describes the part as a model-engine accessory and does not suggest use on full-size vehicles.

The manufacturer lists compatibility with FS120SE, FS120SIII, and FS155P only. Check your engine header thread and stub dimensions to confirm proper fit before installing.

Will this nut fit other engines with M14 threads?

It may fit other engines that use an M14 header thread, but compatibility is only guaranteed for FS120SE, FS120SIII, and FS155P. Always match thread form and stub length before fitting.

How do I confirm correct fit before final tightening?

Hand-thread the nut first to check engagement and alignment. If the nut runs smoothly for several turns, proceed to final tightening while monitoring alignment.

Does using this nut change exhaust tuning?

The nut itself is a fastening item; when it seals correctly it helps maintain the intended exhaust backpressure, which supports consistent tuning results.
