9728A65 - ESAB 1/4 Inch Oxygen Lance Valve Replacement

Precision Control for Exothermic Operations

The ESAB Lance Valve 1/4" (SKU: 9728A65) is a critical component designed for the rigorous demands of thermal lancing and exothermic cutting applications. In heavy industrial environments where burning bars are used to cut through concrete, steel, and other ferrous or non-ferrous materials, the reliability of the oxygen supply mechanism is paramount. This valve is engineered to provide a secure, leak-proof connection between the oxygen supply hose and the lance holder, ensuring that the operator maintains full control over the oxidizer flow that fuels the exothermic reaction.

Constructed from high-quality brass, this valve is built to resist corrosion and withstand the physical abuse typical of demolition and scrap yard environments. Brass is the material of choice for oxygen service due to its non-sparking properties and resistance to ignition in oxygen-enriched atmospheres. The 1/4-inch sizing is a standard specification for many lance holders, making this a versatile replacement part for maintenance teams looking to refurbish existing equipment without sourcing proprietary adapters. The internal seating of the valve is precision-machined to prevent leaks, which is a crucial safety factor when handling high-pressure oxygen.

Maintenance and repair of lancing equipment are essential for operational efficiency. A worn or leaking valve not only wastes expensive gas but can also pose significant safety hazards to the operator. This ESAB replacement valve restores the functionality of the lance holder, allowing for smooth actuation. Whether used in foundries for tapping furnaces, in construction for removing seized pins, or in marine salvage, this valve ensures that the oxygen flow—and thus the cutting power—is available instantly when needed and shuts off completely when the job is done.

Installation is straightforward, utilizing standard NPT thread engagement. It is recommended that all threads be inspected for debris and that oxygen-safe thread sealant is used where appropriate, following industry safety standards for oxygen equipment. This component is an essential spare for any MRO inventory supporting heavy cutting and gouging operations.
