Champion SE541 compression hex nut for air compressors is a 3/4-inch hex nut used as a replacement part to repair the discharge-line connections on Champion air compressors. In Champion assemblies, this compression nut is designated SE541 and is commonly paired with the SE542 sleeve to seal and secure tubing under compression. As a replacement part for compatible Champion air compressors, the SE541 helps restore reliable performance when compression fittings become worn or damaged.
