About O'Keefe Controls Co.

O’Keefe Controls Co. was founded in 1975 by Robert O’Keefe. Combining his experience from
a series of research positions with that from positions at Pitney Bowes and ASCO, Bob started
his own company. O’Keefe Controls Co. began as a distributor of specialty fluid control
products, but now, housed in it’s Monroe, CT location, has since grown into a world leader in
the manufacturing of precision orifices and various flow control products.

As the years passed, our Customer Service reps began to be called upon for parts in special
applications or with specific functions or sizes which were not found in current distributor
catalogs. O’Keefe Controls Co. began custom manufacturing parts for our customers which could not be purchased elsewhere. With a team of top engineers, production personnel and outstanding technical customer service reps, O’Keefe Controls Co. quickly grew to be “The precision orifice capital of the world” as a manufacturing enterprise.
