CGA510-1P - Miller CGA 510 Inlet Nut, Nickel Plated

Premium Replacement Connection Hardware

The Miller CGA510-1P Nut is a specialized gas fitting component designed to facilitate secure connections between compressed gas cylinders and regulation equipment. Manufactured to the Compressed Gas Association (CGA) 510 standard, this nut is engineered for use with fuel gases such as Acetylene, Propane, and Natural Gas. The critical distinction of this component is its electrolytic nickel plating, which provides a significant upgrade over standard raw brass fittings. This plating not only enhances the aesthetic appearance of the equipment but, more importantly, offers robust protection against oxidation, tarnish, and environmental corrosion, ensuring the threads remain clean and functional over extended periods of use.

As a genuine Miller Electric OEM part, this nut guarantees precise dimensional tolerances that aftermarket alternatives may fail to meet. The threading is machined to exact specifications (0.885"-14 NGO-LH-INT), utilizing the standard left-hand thread convention required for fuel gas safety. This design feature is a critical safety control, mechanically preventing the accidental connection of fuel gas equipment to oxygen or inert gas cylinders. Whether used for repairing a damaged regulator inlet, assembling a custom manifold, or replacing worn hardware on a pigtail hose, the CGA510-1P ensures a leak-tight seal when paired with the appropriate nipple.

Industrial environments demand reliability, and the material composition of this nut reflects that requirement. The underlying brass construction provides the necessary tensile strength to withstand high-pressure cylinder connections, while the nickel outer layer acts as a shield against the harsh conditions often found in welding shops and fabrication sites. It is an essential spare part for maintenance teams responsible for keeping oxy-fuel cutting outfits and heating systems operational.
