Sun standard cartridge model codes are comprised of a seven character alpha/numeric combination. Material/coating options are defined using a "slash" modifier appended to the seven character model code. Available options for each model are shown on its respective product page.

Model codes are stamped on one hex face of the cartridge as shown below. A minimum of the first four characters is required when searching. The entire model code is searchable with or without the hyphens. The "/" must be included in the text string when present.
