The TurboTorch 0386-1105 Inlet Swivel & Nut is a critical component designed for professionals who demand reliability in their gas distribution equipment. Engineered specifically for the CGA 520 connection standard, this assembly serves as the primary interface between an acetylene regulator and the cylinder valve. The CGA 520 standard is exclusively utilized for Acetylene "B" tanks (40 cubic feet), which are ubiquitous in the HVAC and plumbing industries due to their portability. This product ensures that the high-pressure connection remains secure, mitigating the risks associated with fuel gas leaks.
Manufactured from high-grade brass, the 0386-1105 offers superior mechanical strength and resistance to deformation under torque. Brass is the material of choice for oxy-fuel fittings due to its non-sparking properties and resistance to atmospheric corrosion. The machining tolerances on the nut and swivel are held to strict OEM specifications, ensuring a smooth engagement with the cylinder valve threads. Unlike generic fittings that may suffer from poor thread quality or soft alloys, this TurboTorch component maintains the integrity of the connection over repeated cycles of cylinder changes.
The assembly consists of the retaining nut and the inlet swivel (nipple). The swivel design is particularly important as it allows the regulator to be oriented in the most convenient position before the nut is fully tightened. This prevents strain on the regulator body and downstream hoses. The sealing surface of the swivel is designed to mate perfectly with the internal seat of the CGA 520 valve, creating a gas-tight seal without the need for excessive force or thread sealants, which are generally prohibited in this application. For maintenance and repair operations (MRO), having a replacement inlet assembly is essential for refurbishing older regulators where the original nut may have become rounded or the seating surface marred.
In industrial supply and inventory management, the TurboTorch 0386-1105 represents a high-turnover replacement part for fleets utilizing portable oxy-acetylene or air-acetylene torch kits. Its specific application to the B-tank size distinguishes it from the larger CGA 510 (POL) or smaller CGA 200 (MC) fittings, making it a targeted solution for specific equipment configurations. Proper identification of the CGA number is crucial for safety and compatibility, and this product clearly meets the industry standards for the 520 designation.
