1369 - CGA 510 Regulator Inlet Nut .880-14 LH

Reliable Gas Connections with ESAB Quality

When dealing with industrial gases, the integrity of your equipment is paramount. The ESAB 1369 Inlet Nut is a critical component designed to ensure a secure and leak-free connection between your gas regulator and the cylinder. Specifically engineered for CGA 510 connections, this nut is the standard for fuel gases such as Acetylene and Propane. Maintaining the condition of your inlet fittings is essential for safety; a worn or damaged nut can lead to dangerous leaks or improper seating of the regulator.

Constructed from high-grade brass, this inlet nut offers superior durability and resistance to the wear and tear typical of welding environments. Brass is the material of choice for these applications due to its non-sparking properties and resistance to corrosion, ensuring that the threads remain clean and functional over time. The nut features a .880-14 LH (Left Hand) thread, a safety feature standard for fuel gases to prevent accidental connection to incompatible gas lines like oxygen. This visual and mechanical distinction is a key part of workshop safety protocols.

Whether you are repairing an existing regulator or assembling a new gas manifold system, using genuine or high-quality replacement parts like the ESAB 1369 ensures compatibility and peace of mind. It is designed to work seamlessly with standard R66 style nipples, providing the compression necessary to create a gas-tight seal. At Josef Gas, we recommend keeping spare inlet nuts in your maintenance kit to prevent downtime caused by stripped threads or rounded hex edges.

Key Applications

This inlet nut is primarily used in the setup and maintenance of oxy-fuel cutting and welding stations. It is compatible with most standard industrial regulators requiring a CGA 510 input. It is suitable for use in heavy fabrication shops, automotive repair centers, and construction sites where fuel gases are frequently swapped and regulators are moved between cylinders.
