17112 - ESAB CGA 520 Acetylene Inlet Nipple .44-20M

Precision Brass Inlet Nipple for Acetylene Gas Service

The ESAB Inlet Nipple (SKU: 17112) is a critical component designed for the safe and efficient transmission of acetylene gas from cylinder to regulator. Manufactured to strict industrial standards, this nipple features a CGA 520 connection, which is the industry standard for Acetylene "B" tanks (40 cubic feet). The use of high-quality brass in its construction ensures excellent resistance to corrosion and mechanical wear, providing a long service life even in demanding workshop environments.

Gas regulation systems rely on precise fittings to maintain pressure integrity and prevent hazardous leaks. This inlet nipple is machined with a .44-20M thread, ensuring a tight and secure fit into compatible regulator bodies. As a genuine ESAB part (often compatible with Victor equipment), it meets rigorous safety specifications required for oxy-fuel applications. Whether you are assembling a new gas manifold system or refurbishing an existing regulator, using OEM-quality fittings is essential for maintaining the safety certification and performance of your equipment.

Proper maintenance of gas equipment involves regular inspection of inlet connections. Over time, threads can become damaged or sealing surfaces can wear, leading to potential gas loss or safety hazards. Replacing a worn inlet nipple with this precision-engineered ESAB component restores the integrity of your connection. It is specifically designed to work in conjunction with a matching inlet nut (sold separately) to secure the regulator to the cylinder valve.
