SENTINEL™ Series Second Stage Dielectric Regulators feature an integral dielectric inlet connection designed to isolate upstream
metallic piping from electrical current prior to piping entering a building in compliance with NFPA 58 – 2020 section 6.11.3.17. Since
the FNPT inlet serves as the dielectric separation media, any standard MNPT threaded connector or valve can be installed without a
separate dielectric union. Both compact and full-size models feature the same basic footprint measurement from inlet to outlet, as
all standard Excela-Flo second stage regulators, making it ideal for regulator change-outs.
