Sizes and part numbers
The Sizes & Part Numbers tab lists each Tompkins number with its thread. Tompkins numbers give the style code, then the dash size of each end in the order the ends are named.
Choosing and fitting
Match each end to the port or tube it meets: JIC 37° and SAE O-ring boss share UNF threads at the same dash size but seal differently (37° flare vs an O-ring on the boss), and ORFS seals on an O-ring in the face. Check the thread before installing; never mix sealing types on one joint.
How to order
Quote the Tompkins part number, or the end types and dash sizes. Price and lead time are confirmed with the quotation.

JIC 9/16"-18 and ORFS 9/16"-18 are the same thread. They will assemble, and one of them will leak. Every designation and pitch we stock, grouped by family, with the collisions marked.

Where JIC is the wrong choice
JIC is the default on most of this continent and it deserves to be. It is also the wrong answer in four specific situations, and every one of them is a situation where people keep specifying it anyway.
