18Z55 - Victor 18Z55 Adapter - 1/2" NPT Male to C-Size Oxygen Male (7/8"-14)

Industrial Grade Connection for Oxygen Distribution

The Victor 18Z55 Adapter is a critical component for industrial gas manifold systems and station drops. Manufactured by ESAB under the Victor brand, this high-quality brass fitting is designed to bridge the gap between standard facility piping and specialized oxygen equipment. It features a 1/2-inch National Pipe Thread (NPT) Male connection on one end and a C-Size Oxygen Male (7/8"-14 threads) connection on the other. This configuration is specifically engineered to allow the attachment of station regulators or hoses directly to a piping drop or manifold outlet.

In large-scale fabrication facilities and workshops, gas distribution often relies on rigid piping systems terminating in NPT fittings. To utilize this gas supply with standard welding regulators, a reliable adapter is required. The 18Z55 provides this interface with precision-machined threads that ensure a tight, leak-free seal. The unit is constructed from solid brass, offering superior durability and resistance to deformation under torque. Furthermore, as an oxygen-service component, it is cleaned and prepared to meet strict safety standards, minimizing the risk of contamination or combustion in oxygen-rich environments.

Reliability for Manifold Systems

Facility managers and MRO specialists trust Victor fittings for their consistency and adherence to CGA standards. The C-Size connection (7/8"-14 RH) is the standard for larger flow oxygen connections, often found on heavy-duty station regulators. By using the 18Z55, you ensure that your infrastructure maintains the integrity required for high-pressure gas delivery. Whether you are outfitting a new facility or replacing worn components in an existing line, this adapter offers the robust performance expected from the leader in gas equipment.
