Deadweight TEST port o-rings (current models, and comparators)

Current model deadweight testers and comparators (except P3800 very high pressure models) all have the same TEST ports and use the same o-rings to seal against the gauge. See the manual 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 an older model that uses bonded seals instead of o-rings see this article, Deadweight TEST port seals (older models, and comparators)

This images below are from a deadweight tester manual (left) and comparator manual (right). The top of the TEST port has an inside diameter of 9.4 mm (0.37 inch). The TEST port insert and smaller o-ring are used with smaller diameter gauge threads. Older models use bonded seals (metal washer with rubber seal on the inside diameter) and have a larger inside diameter of 13.5 mm (0.53 inch).
