1-1/4 inch x 3/4 inch Brass Hex Head Bushing Male x Female

1-1/4 Inch x 3/4 Inch Brass Hex Head Bushing – Reducing Adapter for Threaded Systems

This hex head bushing is engineered to reduce a 1-1/4 inch female threaded opening to accept a 3/4 inch male threaded fitting. Designed for mechanical and plumbing systems requiring durable, corrosion-resistant metal-to-metal thread transitions, it offers reliable performance in both residential and commercial environments.

Manufactured from lead-free brass, this bushing is compliant with potable water standards and suitable for hot and cold water service, low-pressure steam, and various non-potable fluid systems. The hex head design allows for secure tightening using standard wrench tools during system assembly or maintenance.

Product Features

• ✅ Thread Size Reduction – Converts 1-1/4 inch FIP openings to 3/4 inch MIP connections within system manifolds, valve assemblies, or equipment ports.
• ✅ Hexagonal Head – Provides a wrenchable surface for ease of installation and removal in confined or fixed-position assemblies.
• ✅ Corrosion-Resistant Brass – Offers durability in high-humidity, chemical, or temperature-variable environments.
• ✅ Lead-Free Alloy – Certified to meet NSF/ANSI 61 and 372 requirements for use in potable water systems across all jurisdictions.
• ✅ Full-Thread Engagement – Machined to standard NPT threads for secure, leak-resistant mating with compatible fittings.

Installation Considerations

This bushing is intended for threaded applications and should be installed using appropriate thread sealant (PTFE tape or approved pipe dope) to ensure hydraulic sealing. Avoid over-torquing to prevent distortion of mating components. Use standard wrenches on the hex flats to apply torque evenly.

When used in regulated plumbing systems, ensure the material and pressure ratings match the application requirements and comply with governing codes. This component is not designed for crimp, sweat, or press systems.

Typical Use Cases

• Distribution headers or branch connections in copper or brass systems
• Adapting pump outlets or pressure tanks to smaller diameter piping
• Integrating threaded HVAC components or irrigation controls

Material Note

Brass components provide excellent resistance to dezincification and stress cracking. Their thermal stability and strength-to-weight ratio make them a preferred choice for long-term use in a wide range of plumbing and mechanical applications.
