Oklahoma Specialties, Inc.

Oklahoma Specialties, Inc. (OSI) has been meeting forging needs with superior quality for over twenty years. OSI has been a chief manufacturer of hot forged transition nozzles (also known as a “swage”) for box headers on air coolers since 1996.

A transition nozzle allows the width of the header to be shortened. By doing so it saves money in material, consumables and in time welding. The other advantage in using a transition nozzle is that they allow for a much smoother flow in and out of the header which in some cases help’s the corrosion rate of the material.
