1 inch Copper Adapter Fitting x Female

1 Inch Copper Adapter – Female Sweat Connection for Copper Tubing

This 1 inch copper adapter fitting is engineered to provide a secure transition between copper tube and a female-threaded connection. Commonly used in water distribution systems, it enables a durable, code-compliant interface between sweat and threaded components.

Application-Ready for Pressurized Water Systems

Designed for integration into potable water, hydronic heating, and general plumbing installations, this fitting meets the structural and material requirements for demanding system layouts. Key characteristics include:

• ✅ Lead-Free Copper Construction – Manufactured from high-purity copper for corrosion resistance and safe use in drinking water systems.
• ✅ Sweat x Female NPT – Sweat (cup) end accepts copper tubing; opposite end features a female National Pipe Thread for versatile transition connections.
• ✅ Pressure Rated – Suitable for use in residential and light commercial water systems under standard operating pressures and temperatures.

Professional Performance Features

• ✅ Uniform Wall Thickness – Enables even heat distribution during soldering, reducing risk of joint failure.
• ✅ Precision Threads – Tapered for accurate fit and tight sealing when used with approved thread sealants.
• ✅ Reduced Installation Time – Simplifies sweat-to-thread transitions, minimizing field modifications and increasing layout flexibility.
• ✅ Meets Potable Water Code Requirements – Compliant with ANSI/NSF 61 and ANSI/NSF 372 for lead-free applications.

Specification Overview

• Material: Lead-free wrought copper
• Connection Type: Solder (female sweat) x FNPT
• Nominal Size: 1 inch
• Standards: ASME B16.22 / ANSI/NSF 61 & 372

Use Case & Installation Context

This adapter is ideal for terminating copper tube into female-threaded system components such as valves, backflow preventers, or transition fittings. Often used in both retrofit and new construction, it supports reliable performance where copper piping interfaces with brass or iron fittings.

Code Compliance Note

Per federal and state mandates, lead-free copper fittings must be used in all potable water systems. This fitting satisfies those requirements and is certified for use in both horizontal and vertical system configurations.

Engineered for longevity and system integrity, the 1 inch Copper Adapter – Sweat x Female Thread delivers a robust connection point for critical plumbing transitions. Suitable for professional-grade installations in residential and commercial settings.
