H Series — Built for High Pressure
The PEECO H Series is the go-to choice for high-pressure oil & gas service. The solid rod and flexure tube design is field-tested at pressures up to 10,000 PSI — far beyond the capability of standard bellows-type flow switches.
The explosion-proof housing (Class I, Division 1, Group D) meets the electrical classification requirements of most oil & gas facilities. Available in carbon steel, 316SS, and Monel for compatibility with crude oil, produced water, and chemical injection media.
