26422300 - Tweco AK353 Gas Hose Assembly for Lincoln Feeders

Reliable Gas Delivery for Lincoln Wire Feeders

The Tweco AK353 Gas Hose Assembly (Part Number 2642-2300) is a critical component designed for professional welding environments utilizing Lincoln Electric wire feeders adapted for Tweco MIG guns. In industrial fabrication, the integrity of the shielding gas delivery system is paramount to achieving code-quality welds. This specific hose assembly serves as the gas jumper, bridging the connection between the wire feeder's gas solenoid output and the power pin adapter block. Over time, rubber hoses in industrial settings are subject to dry rot, cracking, and mechanical damage, which can lead to insidious gas leaks. These leaks not only waste expensive shielding gas but also introduce atmospheric contamination into the weld pool, resulting in porosity and compromised structural integrity.

Engineered to Tweco's exacting standards, this hose assembly is constructed from high-grade, reinforced synthetic rubber capable of withstanding the rigors of the shop floor. It is specifically sized to fit the barb fittings found on standard Lincoln adapter kits (specifically the AK353 series). The assembly comes complete with a secure hose clamp, ensuring a tight seal that resists vibration and pressure fluctuations common in heavy-duty welding operations. By maintaining a sealed gas path, this component ensures that the full flow of shielding gas reaches the nozzle, providing optimal coverage for the arc and molten puddle.

For maintenance, repair, and operations (MRO) professionals, keeping a spare 2642-2300 on hand is a proactive measure to minimize downtime. When troubleshooting gas flow issues on a Lincoln setup converted to Tweco guns, this jumper hose is often a primary inspection point. Replacing a deteriorated hose with this genuine Tweco part restores the system to factory specifications, ensuring consistent performance and weld quality. It is a small but vital link in the welding process chain, safeguarding the quality of the final product.
