1/2 inch x 3/8 inch Brass Hex Head Bushing Male x Female

1/2 Inch x 3/8 Inch Brass Hex Head Bushing – Male NPT x Female NPT

The 1/2 inch x 3/8 inch Brass Hex Head Bushing is a threaded pipe fitting used to reduce pipe size within systems conveying water, air, oil, or other compatible non-corrosive fluids. Featuring male NPT threads on the larger end and female NPT threads on the smaller end, this bushing provides a mechanically secure transition between differing pipe diameters.

Material Composition and Standards

Manufactured from lead-free brass, this fitting is compliant with federal low-lead requirements and suitable for potable water systems. It is precision-machined to meet ANSI/ASME B1.20.1 thread standards, allowing consistent engagement and sealing performance in pressure-rated piping assemblies.

• ✅ Material: Lead-free brass (meets NSF/ANSI 372 and applicable federal guidelines)
• ✅ Size: 1/2 inch male NPT x 3/8 inch female NPT
• ✅ Head Type: Hexagonal for easy installation with a standard wrench
• ✅ Thread Standard: ANSI/ASME B1.20.1 (tapered pipe threads)

Installation Requirements

Install using appropriate thread sealant or PTFE tape. Ensure clean, undamaged threads prior to assembly. Tighten with a properly sized wrench on the hex head to prevent over-torquing and distortion. Suitable for use in vertical or horizontal pipe runs.

• ✅ Sealant Required: Thread sealant compound or PTFE tape recommended
• ✅ Tool Use: Hex head allows controlled tightening with open- or box-end wrench
• ✅ System Compatibility: Use only with compatible NPT-threaded components

Typical Applications

This brass bushing is used to connect piping or equipment with different threaded sizes in potable water systems, compressed air lines, HVAC piping, pump assemblies, and mechanical rooms. Commonly found in industrial, residential, and light commercial installations.

Performance Characteristics

• ✅ Pressure Rating: Typically suitable for up to 200 PSI in water systems (confirm per system design)
• ✅ Temperature Range: 0°F to 200°F for most non-corrosive media
• ✅ Corrosion Resistance: Brass resists dezincification and internal buildup in potable systems

The 1/2 inch x 3/8 inch Brass Hex Head Bushing provides a code-compliant, mechanically secure solution for adapting between different NPT-threaded pipe sizes. Its compact design and hex profile make it ideal for confined spaces where precision and durability are required in professional-grade installations.
