The B42R-1-1/4 is a gas regulator that features a spring-loaded self-operated regulator. It has a 1/2" x 9/16" orifice, 1" internal relief valve, 6-16" W.C. operating pressure range, and 10 psi maximum allowed operating pressure.
The internal relief gas regulator is designed for consistent pressure reduction of gas in typical domestic and light commercial applications. Its compact size and lightweight construction provide the power, capacity, and relief performance comparable to larger regulators, ensuring safety and longevity in the field.
The B42R-1-1/4 is easy to install with standard threaded connections allowing for field interchangeability of the adjustment spring. The 757623 aluminum orifice and 762646 blue adjustment spring replacement parts are also available.
