What O'Keefe Controls does
O'Keefe Controls Co. is a US-based precision manufacturer of fluid control devices, headquartered at 4 Maple Drive in Monroe, Connecticut. Founded in 1975 and operating for over 40 years (celebrating its 50th anniversary), the company designs and produces precision orifices, check valves, flow controls, fixed flow rate orifices, miniature in-line screens and breathers, miniature stainless steel fittings and bulkhead connectors, and pneumatic float valves and level controls. Its core technical capability is precision micro-orifice machining, with diameters as narrow as 0.0003 inches, supported by NIST-traceable calibration, ultrasonic cleaning of components, flow testing, and 3D CAD rendering with downloadable models. The company is ISO 9001:2015 registered and operates as a Lean Enterprise under a continuous improvement framework.
The company's product portfolio addresses liquid and gas flow metering applications across a horizontal industrial customer base, including vacuum components manufacturing. O'Keefe operates a technical consultative B2B sales motion combining engineering support, custom manufacturing, new product design and development, a parametric search catalog at catalog.okeefecontrols.com, request-quote pricing (no public list pricing), and express ordering for repeat buyers. Revenue is generated through hardware sales of both standard catalog components and customized fluid control solutions sold globally.

Products and services
- Precision Orifices Precision orifices designed for accurate, repeatable flow through the orifice in industrial liquid and gas flow metering applications. Available in metal, sapphire, and micro-orifice variants with diameters as narrow as .0003 inches. Pass stringent quality control testing and are flow tested for consistent performance.
- Check Valves Miniature check valves employing a free-floating stainless steel or buna-n ball, allowing free flow in one direction while preventing reverse flow. Suitable for air, water, inert gases, and light oil applications.
- Flow Controls Tamper-proof, repeatable flow control devices including fixed flow controls and checked orifices designed to provide superior flow control across a broad range of functions.
- Fixed Flow Rate Orifices Fixed flow rate orifices containing a deformable opening that decreases in size as pressure differential increases, compensating for pressure changes to maintain constant flow over the range 15-150 psig. Designed for water applications.
- Miniature In-Line Screens and Breathers Fine screens used to protect orifices and other critical components from particles. Available in 10, 15, 25, and 100 micron particle retention sizes, with stainless steel wire screens to prevent loose particles from entering the fluid stream.
- Mini Stainless Steel Fittings and Bulkhead Connectors Miniature stainless steel fittings including press-fit barb adapters, barb couplings, 10-32 UNF couplers and plugs, and bulkhead connectors for fluid system integration.
- Pneumatic Float Valves and Level Controls Magnetic float valves serving as air sensors for detecting liquid level inside vessels. Float mechanism operates a ceramic-coated magnet with a magnetically actuated sensor on the exterior housing. Available in side-mounted and top-mounted configurations, normally closed or normally open.
