Leading Provider of Instrumentation & Control Solutions
Established in 1976 by Jeff and Susie Spanier, Precision Fitting & Gauge (PF&G) has evolved from a local supplier of tubing fittings and pressure gauges into a premier, multi-million-dollar regional distributor of instrumentation, analytics, control systems, and pressure relief and control valves. Headquartered in Tulsa, Oklahoma, PF&G has built a reputation for excellent service and quality products, expanding its presence to multiple locations across Oklahoma, Texas, Kansas, and New Mexico.
In October 2019, PF&G was acquired by Relevant Industrial, LLC, a leader in instrumentation and automation, rotating equipment, purification, and thermal equipment distribution and service. This acquisition has expanded PF&G’s capabilities and market reach, allowing them to offer more comprehensive solutions to their clients.
