1600860 - Harris 23A90-2 Acetylene Welding & Brazing Tip Size 2

Harris Model 23A90-2 Technical Overview

The Harris Model 23A90-2 Welding and Brazing Tip is a precision-engineered component designed for professional oxy-fuel applications. Manufactured from high-quality tellurium copper, this tip offers excellent thermal conductivity and resistance to deformation under high-heat conditions, ensuring a long service life even in demanding industrial environments. The tip is specifically calibrated for use with Acetylene and Hydrogen fuel gases, providing the specific flame characteristics required for effective welding and brazing.

A key technical feature of the 23A90-2 is its metal-to-metal seating surface. Unlike designs that rely on O-rings or gaskets, this metal seat provides a positive, leak-proof seal that maintains integrity over repeated thermal cycles. The internal bore of the tip is precision drilled and swaged. This manufacturing process ensures the interior walls are perfectly smooth and the exit geometry is exact, resulting in a laminar gas flow that produces a stable, defined flame cone. This model is designed to interface seamlessly with Harris universal mixer sizes 0-10, making it a versatile addition to standard Harris torch setups.

The tip is clearly marked with the Harris logo and the size designation '2', facilitating quick identification in a busy shop environment. It is suitable for a range of material thicknesses appropriate for a size 2 tip and is backed by a one-year warranty, reflecting the manufacturer's confidence in its build quality and performance standards.
