OVERVIEW

High-Performance Brass Bar Stock Bushing

The 1" x 3/4" Brass Bar Stock Bushing is a premium-grade pipe fitting designed for demanding industrial applications. Unlike standard cast fittings, which are poured into molds and can suffer from porosity or structural inconsistencies, this bushing is precision-machined directly from solid brass bar stock. This manufacturing process results in a fitting with superior density, higher tensile strength, and exceptional dimensional accuracy. It is specifically engineered to reduce a 1-inch female port to accommodate a 3/4-inch male pipe or fitting, making it an essential component for versatile piping systems.

Material Properties and Durability

Brass is the material of choice for general-purpose industrial plumbing due to its excellent balance of strength, machinability, and corrosion resistance. This bar stock bushing effectively resists rust and oxidation, making it suitable for use in environments exposed to moisture, water, oil, and various gases. The dense grain structure of the bar stock material ensures that the fitting can withstand higher pressures and mechanical stresses than comparable cast units, providing a long service life even in rigorous operational conditions.

Precision Threads for Leak-Free Seals

One of the critical advantages of bar stock fittings is the quality of the threading. The threads on this bushing are cut with precision tools rather than molded, resulting in sharp, clean NPT (National Pipe Taper) profiles. This ensures a tight, positive engagement with mating parts, significantly reducing the likelihood of leaks. The external 1-inch NPT threads and internal 3/4-inch NPT threads adhere strictly to ANSI/ASME standards, guaranteeing compatibility with a wide range of valves, pipes, and equipment.

Versatile Industrial Application

This reducing bushing is widely utilized across various sectors, including pneumatic control systems, low-pressure hydraulic lines, industrial water plumbing, and gas distribution manifolds. Its hexagonal head design allows for easy installation and removal using a standard adjustable wrench or open-end wrench, providing sufficient torque leverage to achieve a secure seal without damaging the fitting.

FAQ

Bar stock fittings are machined from a solid piece of extruded brass rod, resulting in a denser, stronger material with better surface finish and thread quality. Cast fittings are made by pouring molten brass into a mold, which can sometimes lead to porosity (tiny air pockets) and a rougher finish.

Yes, brass is compatible with inert welding gases such as Argon, Helium, and CO2. It is also suitable for Oxygen service, provided the fitting is cleaned of all oils and grease before installation to prevent combustion hazards.

This bushing has a 1-inch Male National Pipe Taper (NPT) thread on the outside and a 3/4-inch Female NPT thread on the inside.

Yes, NPT threads are designed to seal via an interference fit, but a thread sealant (pipe dope) or PTFE tape is highly recommended to lubricate the threads during assembly and fill any microscopic imperfections for a leak-proof seal.

While bar stock brass is stronger than cast, brass is generally softer than steel. It is suitable for low-to-medium pressure hydraulic applications but should not be used in extreme high-pressure systems where steel or stainless steel fittings are required.

No, brass is highly resistant to red rust. It may develop a patina (darkening) over time due to oxidation, but it will not corrode and flake away like plain carbon steel, making it excellent for water lines.

The bushing features a hexagonal head section. You can use an adjustable wrench, open-end wrench, or a socket of the appropriate size to tighten it securely into the female port.

Brass fittings typically function effectively in temperatures ranging from -65°F to 250°F (-54°C to 121°C), making them versatile for most industrial and shop environments.
