NE154 - Miller Smith NE154 Versa-Torch Propane Brazing Tip End

Technical Overview of the Miller Smith NE154

The Miller Smith NE154 is a specialized screw-on brazing tip end designed for the Versa-Torch series, specifically engineered for HVAC and plumbing applications. This component is manufactured to interface directly with the AT61 threaded tube or the AT600 series twin-flame tip assemblies, providing a modular solution for technicians who require versatility in their torch setups. Unlike universal tips, the NE154 is calibrated specifically for alternate fuel gases, including Propane, Natural Gas, and Propylene, ensuring a stable and efficient flame structure that is not achievable with standard acetylene tips.

Technically, the NE154 provides a substantial heat output suitable for brazing copper piping with an outside diameter (O.D.) ranging from 7/8 inch to 1-5/8 inches. This range covers the majority of residential and light commercial HVAC refrigerant lines. The tip utilizes a screw-on connection mechanism, which ensures a gas-tight seal while allowing for rapid replacement or reconfiguration in the field. It is critical to note that this tip is not designed for use with Acetylene; attempting to use it with incompatible fuel gases can result in flame instability or safety hazards. The precision machining of the orifice ensures consistent gas flow and optimal mixing when paired with the appropriate mixer and handle assembly.

As part of the Smith Equipment product lineage (now under Miller Electric), this tip represents a commitment to quality and durability. It is an essential component for professionals utilizing the Versa-Torch system who need to transition between different pipe sizes or replace worn tip ends without discarding the entire tube assembly.
