0967-0033 - Victor Brass Swivel CGA 540 x 1/4 NPT with Filter

Technical Overview of the Victor 0967-0033 Brass Swivel

The Victor 0967-0033 is a specialized brass swivel assembly designed for high-pressure gas distribution systems. Engineered by Victor, a leader in gas control equipment, this component serves a critical role in connecting oxygen cylinders to manifolds, regulators, or pigtails. The unit features a standard CGA 540 connection on one end, which is the industry standard for oxygen cylinders in the United States, and a 1/4-inch National Pipe Thread (NPT) on the other, allowing for integration into a variety of threaded piping configurations.

One of the defining technical characteristics of this swivel is the inclusion of an integrated filter. This sintered element is strategically placed within the flow path to capture particulate matter and debris that may be present in the gas stream or cylinder valve. By filtering the gas before it enters sensitive downstream components like regulators or flowmeters, the 0967-0033 helps prevent seat damage, creep, and other mechanical failures associated with contamination. The brass construction offers excellent mechanical strength and resistance to oxidation, making it suitable for the oxygen-rich environment it is designed to service.

The swivel mechanism itself is designed to facilitate the attachment of rigid or semi-rigid connections. In manifold applications, where alignment can be challenging, the swivel action allows the nut to rotate independently of the tailpiece, enabling the user to tighten the connection to the cylinder valve without rotating the entire pigtail or piping assembly. This reduces torsional stress on the tubing and ensures a positive seal. The component is rated for standard industrial oxygen cylinder pressures and adheres to the dimensional tolerances required for safe gas service.

Facilities managers and procurement specialists should note that this part is often used as a replacement component for worn manifold leads or as an upgrade to existing pigtails that lack filtration. Its compatibility with standard 1/4" NPT fittings makes it a versatile stock item for MRO (Maintenance, Repair, and Operations) inventories dealing with oxy-fuel cutting and welding infrastructure.
