OVERVIEW

Precision Brass Regulator Outlet Bushing for Fuel Gas Systems

The Western Enterprises 133 Regulator Outlet Bushing is a critical component for industrial gas management systems, specifically designed to adapt regulator bodies to standard hose connections. Manufactured from high-grade free-cutting brass, this bushing ensures structural integrity and resistance to deformation under torque. It serves as an interface between the regulator's internal port and the external delivery system, converting a standard 1/8-inch National Pipe Taper (NPT) female port into a 3/8-inch-24 Unified Fine (UNF) Left-Hand male outlet, commonly referred to as an "A-Size" connection.

In the realm of industrial gas safety, thread direction is paramount. This component features left-hand threads on the outlet side, a mandatory safety standard for fuel gases such as Acetylene to prevent accidental cross-connection with oxygen or inert gas lines (which utilize right-hand threads). The 1/8" NPT male end is tapered, requiring a thread sealant (such as PTFE tape or paste approved for gas service) to create a pressure-tight seal against the regulator body. Conversely, the A-Size outlet relies on a mechanical seating surface compatible with standard A-Size hose nuts, ensuring a leak-proof connection without the need for additional sealants on the flare.

With a maximum pressure rating of 200 PSIG, this bushing is engineered for low-to-medium pressure fuel gas applications. The component features a 7/16" hex section, allowing for precise installation using standard tooling. Its compact length of 1.184 inches ensures a low profile, minimizing leverage on the regulator body and reducing the risk of impact damage. Whether for OEM assembly or MRO (Maintenance, Repair, and Operations) applications, the Western Enterprises 133 provides the reliability and compliance required for professional gas distribution setups.

FAQ

A-Size fittings (3/8"-24 thread) are smaller and typically used for light-duty torches and hoses. B-Size fittings (9/16"-18 thread) are larger and standard for most medium to heavy-duty welding equipment.

No. This bushing has Left-Hand (LH) threads on the outlet, which designates it for fuel gases like Acetylene. Oxygen fittings must have Right-Hand (RH) threads to prevent cross-connection.

You should apply a gas-rated thread sealant (like PTFE tape or paste) to the 1/8" NPT male threads that go into the regulator. Do not apply sealant to the A-Size outlet threads, as the hose connection seals mechanically.

The WES133 is rated for a maximum pressure of 200 PSIG, which is sufficient for acetylene and most fuel gas regulator outlet pressures.

It is manufactured from high-quality brass, which provides excellent durability, corrosion resistance, and is non-sparking for safety in fuel gas environments.

The bushing features a 7/16" RC Hex, so a 7/16" open-end wrench or adjustable wrench is required for installation.

According to the manufacturer specifications, this specific component is not UL listed, though it is manufactured to meet CGA standards.

CGA 021 in this context likely refers to the specific gas service association or fitting geometry standard for this class of acetylene/fuel gas adaptors.
