About
Forty years of making the best air pressure regulator for tubing extrusion
On Line Controls, Inc., is the recognized industry leader in the field of ultra low air pressure regulators for internal air support during the “free” extrusion of plastic tubing, “MicroAir”. OLC has a reputation for manufacturing high quality reliable products which are sold worldwide and have a lifespan of over 10 – 25 years.
While the basic body design of our MicroAirs have been improved upon each year, it still maintains the same outer look and ease of use. MicroAirs precisely regulate and control the internal air pressure for extruded tubing and other types of markets where extremely low air pressure is needed. One of the advantages of a MicroAir is that there is no need for spare parts as they rarely have a problem.

History of On Line Controls:
On Line Controls was incorporated in 1980 in Westboro, Massachusetts by entrepreneur John D. Saint-Amour. The purpose of which was to manufacture on line control systems for plastic tubing manufacturers. The first analog ID and Wall systems were built “UltraGage” in the early 1980’s. Being an analog device the first Wall system controls were the size of a small refrigerator. With the engineering of John Porter, OLC manufactured the first PC based ultrasonic OD/ID/Wall measurement and control system “UltraGage 2000” for plastic tubing manufacturers and the UltraGage 3000 for pipe, from 1990 thru 2007. The UltraGage product line was sold when the owner John Porter retired. UltraGage was discontinued by OLC in 2007. The company then became more focused on our MicroAir and Motorized Potentiometer lines and has since made great improvements in the quality of both these products. The present owners of On Line Controls are employees of the company with over 35 years of experience working in the industry. Kay DeWolfe is currently both an owner and President of On Line Controls, Inc.
In 1997 OLC moved from 158 East Main St, Westborough, MA to 9A Kane Industrial Dr., Hudson, MA. After more than 20 years, On Line Controls moved on March 25, 2020 to our new location at 697 Hartford Turnpike (Route 20), Shrewsbury, Massachusetts 01545 USA.
