OVERVIEW

Reliable Oxygen Connections for Your Welding Setup

When you are building a custom oxy-fuel rig, repairing a vintage regulator, or setting up a specialized torch for jewelry or HVAC work, finding the right fittings is essential. The Western Enterprises 132 Regulator Outlet Bushing is the solution for adapting standard regulator ports to smaller, A-Size oxygen hoses. Many standard regulators and manifolds utilize a 1/8" NPT port, but if your torch or hose uses the smaller "A-Size" connection (common on light-duty equipment), you cannot connect them directly. This high-quality brass adaptor bridges that gap seamlessly.

Safety is paramount when dealing with compressed oxygen. This adaptor is specifically cleaned and rated for Oxygen service (CGA 020) and features right-hand threads. This ensures that you cannot accidentally connect a fuel gas hose (which uses left-hand threads) to your oxygen supply, preventing dangerous cross-contamination. The solid brass construction not only provides a durable, leak-free seal but also resists corrosion over years of use in the shop. Unlike cheap generic fittings, this American-made part from Western Enterprises offers the peace of mind that comes with using professional-grade components.

Installation is straightforward: simply thread the NPT end into your regulator or manifold using an appropriate thread sealant (compatible with oxygen), and you are ready to connect your A-Size oxygen hose. Rated for up to 200 PSIG, this bushing handles standard cutting and welding pressures with ease. Whether you are a professional fabricator, a jeweler, or a hobbyist welder, keeping your gas delivery system leak-free and properly adapted is the first step to a successful project. Don't compromise on your gas equipment; choose the Western Enterprises 132 for a secure and correct fit every time.

FAQ

The inlet is 1/8" NPT Male, and the outlet is A-Size 3/8"-24 UNF Right Hand Male.

It is designed for Oxygen service and conforms to CGA 020 standards.

No. This fitting has right-hand threads, which are for oxygen and inert gases. Fuel gases like acetylene typically require left-hand threads to prevent cross-connection.

A-Size fittings (3/8"-24 threads) are smaller and typically used for light-duty torches and hoses. B-Size fittings (9/16"-18 threads) are larger and used for standard industrial equipment.

This bushing is rated for pressures up to 200 PSIG.

It is machined from high-quality brass.

No, this is a simple brass adaptor bushing. It does not contain internal check valves or flash arrestors.
