A seal code is an abbreviated method of communiing basic specifiions for the mechanical seal. Sadly, the seal code has been changed with every edition of API 682. Fortunately, the new code, described in API 682 4 th Edition Annex D, is the best to date and includes some concepts and codes from the historical API 610 seal code.
