OVERVIEW

Precision Brass Pipe Fittings for Industrial Applications

The Brass Hex Bushing 3/8" x 1/4" is an essential component for professionals managing gas distribution systems, pneumatic lines, and welding manifolds. Manufactured from high-quality brass, this fitting is designed to withstand the rigors of industrial environments while resisting corrosion and rust. Brass is the material of choice for many welding and gas applications due to its durability and compatibility with a wide range of inert gases.

This specific bushing functions as a reducer, allowing you to adapt a 3/8-inch NPT female port to accept a 1/4-inch NPT male fitting. The National Pipe Taper (NPT) threads are precision-cut to ensure a tight, positive seal that prevents leaks—a critical safety factor when dealing with pressurized gases. The hexagonal head design is a practical feature that allows for easy installation and removal using a standard adjustable wrench or open-end wrench, providing enough torque to seat the threads firmly without damaging the fitting.

Whether you are assembling a custom gas manifold, repairing a regulator, or configuring a pneumatic control system, this brass bushing provides the reliability and fitment accuracy required for professional results. Its compact design ensures it adds minimal length to your assembly while providing a robust connection point.

Key Technical Benefits

Unlike steel fittings which may rust, or plastic fittings which may lack the necessary pressure rating for certain gas applications, brass offers a balanced solution of strength and longevity. It is soft enough to create a good seal against other metals but hard enough to resist stripping under normal torque conditions. This fitting is an indispensable part of any maintenance repair and operations (MRO) inventory.

FAQ

This bushing features National Pipe Taper (NPT) threads. It has a 3/8" Male NPT thread on the outside and a 1/4" Female NPT thread on the inside.

Yes, NPT threads are designed to seal via an interference fit, but using Teflon tape or a suitable pipe thread sealant is highly recommended to ensure a leak-free connection, especially for gas applications.

Brass is generally suitable for oxygen service, but all components in an oxygen system must be cleaned specifically for oxygen service to remove oils and grease. Ensure the fitting is 'oxygen clean' before use in pure oxygen environments.

Yes, brass is corrosion-resistant and is commonly used in water plumbing and cooling systems for welding equipment.

You will need a standard adjustable wrench or an open-end wrench that fits the hex portion of the bushing to tighten it securely.

A bushing is used to reduce the size of a female port (it has male threads on the outside and female on the inside), whereas a coupling typically connects two male pipes of the same or different sizes (female threads on both ends).

No, bushings are directional reducers. This specific part is designed to screw into a 3/8" hole and allow a 1/4" part to screw into it.
