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.

Failure analysis
Using sealant on hydraulic threads: which joints want it, and which are ruined by it
Tape on a tapered thread is correct. Tape on a cone, a flat face or an O-ring boss is how a good joint is made to leak — and how debris gets into the system.

Specification & standards
Stopping an NPT leak: tape, sealant, or neither
A tapered thread seals on the thread itself, which is why it needs help. Every other connector on the machine seals somewhere else, which is why putting tape on it makes the leak worse.

Thread & fitting identification
NPT, NPSM and SAE hose fittings: taper, swivel, flare and O-ring boss
Five American hose-end families that get confused because they share inch sizes. Which seals on the thread, which on a cone, which on an O-ring — and how to tell NPT from NPSM before it leaks.
