Description
Use the table below to compare part numbers, tube outside diameters, JIC thread sizes, pipe-thread sizes, overall lengths, and hex dimensions.
Tube OD identifies the corresponding tube outside diameter. It is not the outside diameter of the JIC thread. Specify both connection ends when selecting an adapter, as the JIC size and pipe-thread size may differ.
Before ordering, confirm the dimensions and pressure rating for the selected part number. The allowable operating pressure of the completed connection is limited by its lowest-rated component under the applicable service conditions.
