Champion SE542 is a compression ferrule designed for 3/4" outer-diameter tubing, a genuine Champion replacement part used with compression fittings in air compressor discharge lines. It is intended for 3/4" copper tubing in discharge piping configurations common to Champion systems and is typically paired with the respective fitting components in Champion's R-Series and related units. Made in the USA, the SE542 ferrule is distributed through authorized Champion parts channels as a standard repair item for 3/4" tubing installations.
