CGA540-2E - Miller CGA 540 Brass Tailpiece, 3-Inch Length

Precision Engineered Gas Connection Component

The Miller CGA540-2E Tailpiece is a critical component designed for professional gas distribution systems, specifically tailored for Oxygen service utilizing the CGA 540 standard. Manufactured from high-quality brass, this tailpiece offers the mechanical strength and oxidation resistance required for high-pressure cylinder and manifold applications. The 3.00-inch Overall Length (OAL) distinguishes this unit from standard short nipples, providing necessary spacing and clearance in complex piping arrangements or when retrofitting regulators to specific manifold blocks.

Material Specifications and Compatibility

In the realm of industrial gas equipment, material integrity is paramount. This tailpiece is machined from brass alloy specifically selected for its compatibility with oxygen. Unlike ferrous metals which can spark, or lower-grade alloys that may degrade under high-pressure oxygen flow, this brass component ensures a safe, non-reactive path for gas transmission. The machining tolerances on the seating surface are executed to meet strict industry standards, ensuring that when mated with a corresponding CGA 540 nut and cylinder valve or manifold outlet, a positive, leak-tight seal is achieved. This metal-to-metal sealing capability is essential for maintaining system pressure and preventing hazardous leaks.

Application in Industrial Environments

Industrial MRO professionals often encounter situations where standard fittings do not suffice due to spatial constraints or specific equipment designs. The extended 3.00-inch length of the MILCGA540-2E allows for deeper insertion or extension from the gas source, facilitating the connection of regulators, pigtails, or high-pressure hoses in tight or recessed configurations. It is an indispensable part for technicians repairing or assembling gas blending panels, cylinder filling stations, and heavy-duty welding carts where robust, reliable connections are non-negotiable. The component integrates seamlessly with existing Miller gas equipment as well as other standard CGA 540 hardware.

Safety and Compliance

Adhering to Compressed Gas Association (CGA) standards, this tailpiece ensures that connections are made only with compatible gas services, preventing cross-connection accidents. For oxygen systems, cleanliness and material suitability are critical to prevent adiabatic compression ignition. This Miller tailpiece is produced with these safety factors in mind, providing a reliable link in the gas delivery chain that maintenance personnel can trust.
