B-40 - CGA-510 to 1/4 Inch NPT Female Brass Bushing Adaptor

High-Performance Brass Bushing for Industrial Gas Systems

The Western Enterprises B-40 Bushing is a critical component for professionals managing compressed gas systems, specifically those utilizing Acetylene or Propane services. Engineered with precision, this bushing serves as a robust adaptor, converting a CGA-510 connection to a standard 1/4-inch NPT Female thread. This capability is essential for integrating regulators, manifolds, and pigtails into broader piping infrastructures or custom equipment setups where thread compatibility is paramount.

Manufactured from high-grade free-cutting brass, the B-40 bushing offers superior machinability and structural integrity. Brass is the material of choice for these applications due to its non-sparking properties—a vital safety feature when working with flammable gases like Acetylene. Furthermore, the material provides excellent resistance to corrosion and wear, ensuring that the threads maintain their profile even after repeated assembly and disassembly cycles. This durability translates to a lower risk of leaks and a longer service life in demanding industrial environments.

The fitting features a CGA-510 connection, which is the standard for Acetylene (POL) and Propane cylinders and regulators. It is important to note that CGA-510 connections typically utilize left-hand threads to prevent accidental cross-connection with non-compatible gas lines, while the NPT side utilizes standard right-hand tapered pipe threads. The B-40 is rated for pressures up to 500 PSIG, making it suitable for the typical working pressures found in fuel gas delivery systems. Whether used in a laboratory setting, a heavy fabrication shop, or a portable welding rig, this bushing ensures a secure and compliant connection.

Compliance and safety are at the forefront of the design. Made in the United States, this product meets strict quality control standards. Users should be aware that, like many brass components, it contains lead and carries a Proposition 65 warning. However, for its intended industrial application, it remains the industry standard for reliability and performance.
