NE136B - Miller Smith 2-Outlet Fuel Gas Manifold B-Connection

Precision Gas Distribution for Industrial Applications

The Miller NE136B Manifold is a specialized gas distribution component designed to expand the utility of standard fuel gas regulators. Engineered by Miller Electric (often associated with the Smith Equipment heritage of high-quality gas apparatus), this manifold serves the critical function of splitting a single fuel gas supply line into two independent outlets. This capability is essential in industrial environments where multiple operators or applications require simultaneous access to fuel gas from a centralized cylinder or station drop. The unit is constructed from high-grade brass, a material chosen for its excellent machinability, resistance to sparking, and durability against the corrosive nature of certain industrial environments.

Technically, the NE136B features standard CGA "B" size connections with 5/8"-18 threads. Crucially, these threads are Left-Hand (LH), adhering to the universal safety standard for fuel gases such as Acetylene, Propane, Propylene, and Natural Gas. This distinct threading prevents accidental cross-connection with Oxygen lines, which utilize Right-Hand threads, thereby mitigating the risk of catastrophic mixing of gases. The manifold attaches directly to the outlet of a pressure regulator or a pipeline station valve, effectively converting a single-outlet source into a dual-outlet station. This allows for the connection of two separate hoses, enabling two torches to be operated at the same pressure setting, provided the regulator has sufficient flow capacity to support the combined load.

The internal geometry of the manifold is designed to minimize flow restriction, ensuring that both outlets receive an adequate supply of gas. While it acts as a splitter, users must be aware that it does not independently regulate pressure for each outlet; both lines will operate at the pressure set by the upstream regulator. Therefore, it is best suited for applications where both connected tools require similar operating pressures. The robust brass body is resistant to mechanical impact and deformation, ensuring a long service life even in rugged workshop settings. For safety and maintenance, the precision-machined threads ensure a gas-tight seal when paired with compatible B-size nuts and nipples, reducing the likelihood of leaks which are particularly hazardous with flammable fuel gases.

In summary, the Miller NE136B represents a simple yet indispensable solution for scaling gas operations. It embodies the reliability expected from Miller's gas equipment line, providing a secure, leak-proof, and standard-compliant method for doubling the connectivity of fuel gas systems.
