1800720 - Harris J-63-2 Acetylene Heating Tip & Tube Assembly

Harris Model J-63-2 Heating Tip and Tube Combination

The Harris Model J-63-2 (SKU: 1800720) is a premium single-piece heating tip and tube combination designed specifically for oxy-acetylene and oxy-hydrogen heating applications. Engineered for professional industrial environments, this assembly represents the high standard of quality associated with Harris Products Group. The unit is constructed entirely from high-grade copper, a material chosen for its superior thermal conductivity and resistance to the intense heat generated during prolonged heating operations. Unlike multi-part assemblies that may loosen or degrade over time, the single-piece construction of the J-63-2 ensures structural integrity and long-term reliability.

Technically, the J-63-2 is designed to operate using an "E" equal or positive pressure mixing system. This configuration is critical for maintaining a stable and safe flame profile, particularly when dealing with the high volumetric flow rates required for heavy heating. The tip connects to the mixer via a 23/64" - 26 UNS (RH) thread. A standout engineering feature of this model is its metal-to-metal contact seats. These precision-machined surfaces provide a gas-tight seal when connected to genuine Harris mixers (such as the E-43 or D-85), completely eliminating the need for thread sealants or Teflon tape. This not only simplifies maintenance and tip changes but also prevents the potential contamination of the gas path with foreign sealant materials.

This specific model, the size 2, is calibrated to deliver a substantial heat output suitable for a variety of metalworking tasks. It is compatible with Harris handles that utilize the aforementioned mixers, including the 43-2 and 63 series handles. The tip is clearly marked with its model number and size, facilitating quick identification in a busy shop environment. By integrating the tip and tube into one seamless copper unit, Harris has optimized the gas flow characteristics, reducing turbulence and ensuring a focused, efficient heating flame. Whether used for preheating prior to welding, bending steel, or straightening distorted components, the J-63-2 delivers consistent performance.

Operators should note that this tip does not include the mixer itself; it is a replacement or accessory tip-tube combination intended to screw into an existing compatible mixer. The robust copper design also aids in rapid heat dissipation, helping to keep the tip cooler during operation compared to brass or alloy alternatives, thereby extending the service life of the consumable.
