The Exergy M18x1.5 rail end to M14x1.5 adapter converts an M18x1.5 rail end to an M14x1.5 threaded interface for fuel-rail plumbing. It’s intended where a rail-end thread downsize or transition to M14x1.5 is required in CP3 or HP rail setups. Use this adapter when matching an M18x1.5 rail end to components or fittings that accept M14x1.5 threads.
