1-1/2 inch x 1 inch Brass Hex Head Bushing Male x Female

1-1/2 inch x 1 inch Lead-Free Brass Hex Bushing – Male x Female NPT

This 1-1/2 inch x 1 inch hex bushing is manufactured from lead-free brass and designed for reducing pipe size in plumbing and mechanical systems. It features a hexagonal head for easy wrench application and is threaded male on the larger end and female on the smaller end, both conforming to ANSI/ASME B1.20.1 NPT standards.

Application and Use

Commonly used in potable water systems, compressed air lines, oil distribution, and other industrial or residential applications, this fitting supports reliable performance under variable pressures and temperatures. The lead-free brass composition meets U.S. Safe Drinking Water Act (SDWA) requirements and is suitable for use in systems delivering water for human consumption.

Performance and Construction Features

• ✅ Material: Lead-free brass (<0.25% lead content) for compliance with NSF/ANSI 61 and 372 standards.
• ✅ Connection Type: 1-1/2 inch Male NPT x 1 inch Female NPT – tapered threads for a secure, pressure-tight seal.
• ✅ Temperature Range: Rated for use in systems up to 400°F (204°C), depending on sealant and installation conditions.
• ✅ Pressure Rating: Typically supports working pressures up to 1200 psi (liquid); check system parameters before installation.
• ✅ Corrosion Resistance: Brass provides long-term durability and resistance to dezincification under normal conditions.

Installation Guidance

Apply appropriate thread sealant (such as PTFE tape or pipe joint compound) to male threads before installation. Hand-tighten, then wrench-tighten to recommended torque. Avoid over-tightening to prevent thread damage. Ensure alignment and fitment meet all code and job-specific requirements.

Field Usage

Frequently installed in domestic water supply networks, hydronic heating loops, and other low- to mid-pressure systems requiring reduction from 1-1/2 inch to 1 inch pipe size. Compatible with copper, CPVC, PEX (when using threaded adapters), galvanized steel, or other brass components.

Compliance Note

This fitting is certified as lead-free and is suitable for use in plumbing applications under current federal and state regulations. It helps meet code compliance for potable water distribution under the Safe Drinking Water Act and related health codes.

The 1-1/2 inch x 1 inch lead-free brass hex bushing provides a reliable, compact solution for step-down connections in threaded piping systems. Designed for ease of installation and built to handle demanding plumbing environments, this fitting is a standard component in professional mechanical assemblies.
