about us
A Legacy of Precision. A Future of Performance.
Haygor Instrument & Company, Inc. started in 1973 as a small job shop in Pasadena, Texas. Since then, we’ve grown into a globally recognized name in diaphragm seal manufacturing and process instrumentation services.
In 2017, Allen Bishop—who had spent decades working his way up through the company—took the reins from founder George Bishop. Today, Allen continues to lead Haygor with a clear vision: drive innovation, deliver exceptional service, and put customers first. Haygor remains proudly privately owned, with locations in Houston, Pasadena, and Bridge City, Texas. Our headquarters are now based at our expanded Preston facility in Pasadena.
