17113 - CGA 200 Acetylene Regulator Inlet Nipple - .44-20 Thread

Technical Overview: ESAB 17113 CGA 200 Inlet Nipple

The ESAB 17113 is a specialized replacement inlet nipple designed for Compressed Gas Association (CGA) 200 connections. This fitting is critical for the safe operation of oxy-fuel regulators utilized with "MC" style acetylene cylinders (typically 10 cubic feet capacity). Manufactured from high-grade brass, the nipple offers superior resistance to deformation and corrosion, ensuring a long service life even in demanding industrial environments.

The nipple features a precision-cut .44-20 thread profile, engineered to mate perfectly with standard CGA 200 inlet nuts. The seating surface is machined to strict tolerances to facilitate a gas-tight seal when paired with the appropriate sealing washer (sold separately). In gas regulation systems, the inlet nipple acts as the primary bridge between the high-pressure cylinder valve and the regulator body. Maintaining the integrity of this component is essential for preventing hazardous gas leaks and ensuring consistent flow rates.

Technicians and MRO professionals will appreciate the dimensional accuracy of this component, which simplifies the refurbishment of vintage or damaged regulators. Whether performing routine maintenance or addressing thread wear on existing equipment, the ESAB 17113 provides a reliable OEM-quality solution. It is compatible with a wide range of regulator bodies that adhere to the CGA 200 standard for acetylene service.

Specifications and Compatibility

This component is strictly for use with Acetylene gas in the MC cylinder configuration. It is not compatible with CGA 510 (large POL) or CGA 520 (B-tank) connections. Proper installation requires a compatible inlet nut and potentially a sealing washer depending on the specific regulator design. Users should verify thread pitch and diameter requirements before installation to ensure safety compliance.
