1/4 inch x 1/8 inch Brass Hex Head Bushing Male x Female

1/4 inch x 1/8 inch Lead-Free Brass Hex Bushing – Threaded Reducing Fitting for Potable and Low-Pressure Systems

The 1/4 inch x 1/8 inch hex bushing is a precision-machined lead-free brass fitting designed to reduce female-threaded openings to a smaller male-threaded size. Commonly used in low-pressure air, water, oil, and hydraulic applications, this bushing is engineered to maintain mechanical integrity and dimensional accuracy under typical operating conditions.

Key Performance Features

• ✅ Lead-Free Brass Composition – Complies with federal potable water safety requirements including NSF/ANSI 61 and 372 for use in drinking water systems.
• ✅ Hexagonal Body Design – Allows for secure torque with standard wrenching tools, enabling fast and accurate installation in confined spaces.
• ✅ Thread Standards – Male and female NPT threads conform to ANSI/ASME B1.20.1 for compatibility with threaded pipe and fittings.
• ✅ Corrosion Resistance – Suitable for use in environments where contact with water, non-acidic fluids, or mild atmospheric exposure is expected.

Technical Specifications

• Material: Lead-Free Brass (≤0.25% Pb content)
• Nominal Sizes: 1/4 inch Male NPT x 1/8 inch Female NPT
• Operating Pressure: Typically rated up to 200 psi at ambient temperature (verify with system specifications)
• Temperature Range: Up to 250°F (121°C) depending on system media and sealing methods

Installation Guidance

This fitting is intended for use in systems where threaded pipe reductions are required. Install with thread sealant (PTFE tape or anaerobic compound) to ensure leak resistance. Torque should be applied with an appropriately sized wrench on the hex body. Avoid overtightening to prevent thread deformation or damage to connected fittings.

Typical Applications

Commonly installed in potable water supply lines, instrument air systems, compressed gas controls, and hydraulic test assemblies where a reduction from 1/4 inch to 1/8 inch NPT is needed. Suitable for both residential and light commercial use.

Did You Know?

Hex bushings offer a compact alternative to multi-fitting reductions, reducing joint count and minimizing leak points. Lead-free brass components are now required in public water systems under the U.S. Safe Drinking Water Act.

The 1/4 inch x 1/8 inch lead-free brass hex bushing offers precision, compliance, and durability for demanding plumbing and mechanical system requirements. It’s a dependable choice for any professional-grade piping assembly where space, safety, and sealing integrity are priorities.
