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

Current model deadweight testers and comparators 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.

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).
