20002175 - Tweco Brass Gas Nipple Replacement 2000-2175

Technical Overview of the Tweco 2000-2175 Gas Nipple

The Tweco 2000-2175 Gas Nipple is a critical component designed for the gas distribution systems within specific Tweco MIG gun assemblies and adapters. Manufactured from high-grade brass, this nipple serves as the primary interface for channeling shielding gas from the supply hose into the power pin or adapter block of the welding torch. The choice of brass as a manufacturing material ensures high resistance to oxidation and corrosion, which is vital in environments where the component may be exposed to atmospheric moisture and industrial contaminants.

Precision machining tolerances are strictly adhered to during the production of this component to ensure a gas-tight seal when mated with corresponding female threads or compression fittings. In MIG welding (GMAW), the integrity of the gas delivery system is paramount; even minor leaks at the connection points can lead to turbulent flow or atmospheric contamination of the weld pool, resulting in defects such as porosity. This gas nipple is engineered to maintain laminar flow characteristics by providing a smooth internal bore that minimizes turbulence as the gas transitions into the gun liner system.

This part is identified by the internal SKU TWE2000-2175 and is supplied as a bagged item. It is intended for use by maintenance personnel and welding technicians who are repairing or refurbishing Tweco-style MIG equipment. Proper installation requires ensuring that the mating surfaces are clean and that the nipple is torqued to specification to prevent thread damage while ensuring a hermetic seal. It is compatible with a range of Tweco adapters, making it a versatile spare part for workshops utilizing Tweco interconnection systems.
