1403-0013 - Victor Brass Cap Nut 5/8-18 Thread Replacement Part

Genuine Victor 1403-0013 Brass Cap Nut

The Victor 1403-0013 Cap Nut is a critical replacement component designed for precision and safety in oxy-fuel gas equipment. Manufactured from high-grade brass, this cap nut offers exceptional durability and resistance to corrosion, which is essential for components exposed to various industrial environments and atmospheric conditions. The use of brass also ensures that the part remains non-sparking, a vital safety feature when working with flammable gases such as acetylene, propane, or natural gas.

This specific cap nut features a 5/8-18 thread size, a standard Unified Fine (UNF) thread profile often utilized in gas regulation and distribution equipment. The precision machining of the threads ensures a tight, secure fit that maintains the integrity of the pressure boundary within the device. Whether used to cap off a port, retain a valve assembly, or secure a regulator bonnet, the 1403-0013 is engineered to meet Victor's rigorous original equipment manufacturer (OEM) specifications. Using genuine OEM parts is crucial for maintaining the UL listing and safety certification of your gas apparatus.

In industrial maintenance, repair, and operations (MRO), the reliability of small fittings can dictate the uptime of larger systems. A worn or cross-threaded nut can lead to gas leaks, pressure inconsistencies, or equipment failure. By choosing the genuine Victor 1403-0013, technicians ensure that the replacement part matches the exact tolerances of the original component, facilitating a smooth installation process and restoring the equipment to its optimal operating condition. This part is compatible with specific Victor regulators and torch handles requiring a 5/8-18 brass cap nut.

Proper installation involves ensuring the mating threads are clean and free of debris. The hex-head design allows for standard wrench tightening, providing sufficient torque to seat the component without damaging the softer brass threads. This balance of strength and malleability helps create a gas-tight seal when used in conjunction with appropriate seating surfaces or O-rings, depending on the specific assembly configuration.
