United Brass Works 34041 High Pressure Boiler Gauge Fixture Set Overview
The United Brass Works 34041 is a high pressure boiler gauge fixture set with ball check designed for water-level indication systems used on steam boilers. The assembly provides the upper and lower gauge connections required for installation of a gauge glass, allowing operators to visually monitor the boiler water level during operation.
The Model 34041 uses an offset design and incorporates union bonnets with blowout-proof stems. Its union tail pieces provide approximately 1/8 inch of adjustment, helping facilitate proper alignment of the upper and lower fixtures during installation. These features make the assembly suitable for industrial boiler installations where accurate positioning of the water gauge assembly is required. United Brass Works, Inc.
The United Brass Works 34041 is rated for 250 WSP at a maximum temperature of 406°F. United Brass Works also lists the fixture set as compliant with ASME B31.1 and with Section I, PG-60, Appendix A-18 of the ASME Boiler Code, making it specifically suited to boiler water-level gauge applications.

The complete assembly uses a Model 902 1/2-inch upper fixture, a Model 903 1/2-inch lower fixture, and a steel protector rod set. According to the manufacturer’s specification sheet, the assembly has an approximate unit weight of 6.5 pounds. United Brass Works, Inc.
The integrated ball-check arrangement provides an additional protective function in the gauge system. Boiler gauge fixture ball checks are intended to help reduce the release of steam or water in the event the gauge glass breaks. United Brass Works lists its high-pressure fixture assemblies among the products designed specifically for direct boiler and water-column installations. United Brass Works, Inc.
Correct alignment of a boiler gauge glass assembly is important for dependable water-level indication. The adjustable union tail pieces on the Model 34041 provide additional flexibility during installation, while the offset configuration allows the upper and lower valves to be positioned appropriately for the gauge glass.
United Brass Works specifies that the proper gauge glass length can be determined by subtracting 3/4 inch from the center-to-center dimension of the installed valves. The gauge glass itself should be selected according to the dimensions and requirements of the specific boiler installation. United Brass Works, Inc.
