Deadweight TEST port seals (older models, and comparators)

Most of the older model Pressurements and SI deadweight testers and comparators have bonded seals on the TEST ports. See the manual or handbook for your model for more details, and/or search the Deadweight Testers section of our Online Knowledge Base for more information (seal kits, old manuals, handbooks, etc.)

If you have a current model that uses o-rings instead of bonded seals see this article, Deadweight TEST port o-rings (current models, and comparators)
