23612590 - ESAB PSF Connection Tube with O-Ring

Product Overview

The ESAB 23612590 Connection Tube with O-Ring is a precision-engineered replacement component designed specifically for the ESAB PSF series of MIG welding guns. As a critical element in the torch assembly, this connection tube serves as the mechanical and electrical bridge between the torch cable assembly and the swan neck (torch neck). Manufactured to ESAB's exacting OEM standards, it ensures that your welding equipment maintains its original performance specifications regarding current transfer and shielding gas delivery.

Constructed from a durable, high-conductivity brass alloy, this connection tube is built to withstand the thermal cycling and mechanical stresses inherent in industrial welding environments. The component features precision-machined threads that ensure a secure fit, minimizing electrical resistance which can otherwise lead to overheating and premature failure of torch components. A key feature of this assembly is the included O-ring, which provides a hermetic seal for the shielding gas channel. A compromised connection tube or O-ring is a common source of gas leakage, which can result in turbulent gas flow, atmospheric contamination of the weld pool, and ultimately, porosity in the finished weld.

Maintenance professionals and welding engineers understand that using genuine replacement parts is vital for the longevity of high-performance equipment like the PSF series. The 23612590 connection tube is compatible with various models within the PSF line, including the widely used PSF 405 and PSF 505 guns. By replacing worn or damaged connection tubes with this genuine ESAB part, you ensure the safety of the operator and the quality of the welding output.

Technical Specifications
