1-1/2 inch Copper Adapter Lead-Free Fitting x Male

1-1/2” Copper Adapter – Sweat x Male Thread Transition Fitting for Potable Water Systems

The 1-1/2” Copper Adapter is a solder joint x male NPT (MIP) fitting used to transition from copper tubing to threaded pipe in potable water and mechanical systems. Manufactured from lead-free wrought copper, this fitting provides a secure and code-compliant solution for connecting copper piping to valves, fittings, or threaded equipment.

Designed for soldered copper systems, the adapter features a socket (cup) end for sweat connections and a male-threaded end for NPT-compatible components. It is suitable for use in pressure-rated systems carrying hot or cold water, as well as in hydronic and low-pressure HVAC applications.

Technical Specifications

• Material: Lead-Free Wrought Copper
• Size: 1-1/2 inch nominal pipe size
• Connection Type: Sweat (Socket) x Male NPT
• Applicable Standards: ASME B16.22, ASTM B75/B88, NSF/ANSI 61 & 372

Product Features

• ✅ Dual-Function Design – Allows direct transition between copper pipe and threaded metal pipe or equipment.
• ✅ Lead-Free Construction – Certified for drinking water applications in accordance with federal low-lead requirements.
• ✅ High-Pressure Compatibility – Suitable for domestic water pressure and temperature conditions.
• ✅ Corrosion Resistant – Copper construction resists scaling and chemical degradation over time.

Installation Guidelines

Use standard copper tube preparation and soldering techniques for the sweat end. Clean and flux the socket and pipe, apply heat evenly, and solder using lead-free alloy. For the threaded end, use PTFE tape or approved pipe dope and avoid overtightening to maintain thread integrity. Install per local plumbing code and system specifications.

Common Applications

Typically used in water heater connections, valve assemblies, pump tie-ins, and manifold installations. Suitable for residential and commercial potable water systems, particularly where a threaded transition is needed from copper piping.

Regulatory Compliance

This fitting complies with the Safe Drinking Water Act and is certified lead-free under NSF/ANSI 372. It also meets dimensional and pressure criteria as defined by ASME B16.22 for solder-joint copper fittings.

The 1-1/2” Copper Sweat x Male Adapter provides a reliable and code-compliant method for transitioning between soldered copper pipe and threaded system components. Its lead-free construction and standard dimensions make it a trusted choice in high-integrity potable water installations.
