3/4 inch x 1/2 inch Brass Face Bushing

3/4 inch x 1/2 inch Brass Face Bushing – Threaded Reducing Fitting for Pressure and Mechanical Piping Systems

The 3/4 inch x 1/2 inch Brass Face Bushing is a hex-head reducing fitting used to transition between threaded openings of differing sizes in pressurized and mechanical piping systems. Manufactured from lead-free brass, it provides corrosion resistance, structural reliability, and compliance with potable water regulations.

Designed to be installed in female-threaded outlets, this bushing reduces 3/4 inch NPT openings down to 1/2 inch NPT, supporting a wide range of system configurations. Its robust construction and precision-machined threads offer a secure, vibration-resistant seal in fluid, gas, or air lines.

Technical Specifications

• Nominal Sizes: 3/4 inch Male NPT x 1/2 inch Female NPT
• Material: Lead-free brass (NSF/ANSI 61 & 372 compliant)
• Design: Hex face for wrench installation; face bushing configuration allows flush installation in fitting or manifold
• Thread Type: ANSI B1.20.1 NPT tapered threads
• Pressure Rating: Suitable for 200–300 PSI depending on application and system medium

Installation Guidelines

Apply a compatible thread sealant or PTFE tape suitable for the system media. Use a properly sized wrench to tighten the bushing at the hex face—avoid overtightening to maintain thread integrity. Always test the assembly per system requirements to verify leak-free operation before commissioning.

Applications

This brass face bushing is used in potable water supply lines, compressed air systems, and low-pressure gas piping. Typical installations include valve and manifold outlets, pressure gauges, boiler connections, and backflow prevention assemblies.

Material Insight

Brass fittings offer excellent corrosion resistance and thermal stability. The lead-free alloy complies with U.S. Safe Drinking Water Act requirements, making it suitable for use in municipal, commercial, and residential water systems.
