1 inch Copper Adapter Fitting x Male

1 inch Lead-Free Brass Adapter – Threaded Fitting for Potable Water Systems

This 1 inch brass adapter is manufactured from lead-free brass and provides a secure male-threaded connection for joining compatible plumbing components in pressurized potable water and hydronic systems. It is designed to ensure mechanical integrity and long-term reliability in both residential and commercial piping networks.

Machined to NPT standards with tight dimensional tolerances, this adapter supports proper engagement with female-threaded pipe or fittings, minimizing the risk of leakage at connection points. Its corrosion-resistant alloy is suitable for use in environments subject to water, temperature variation, and mechanical stress.

Product Features

• ✅ Lead-Free Brass Composition Meets Safe Drinking Water Act (SDWA) requirements for systems carrying potable water.
• ✅ Male National Pipe Thread (NPT) Compatible with ANSI B1.20.1 standard fittings for reliable threading and sealant coverage.
• ✅ High Tensile Strength Withstands system pressures typical in municipal water supply and closed-loop heating systems.
• ✅ Corrosion Resistance Brass alloy resists dezincification and internal scale formation under standard service conditions.
• ✅ Machined for Uniformity Provides consistent thread depth and face finish for dependable mechanical coupling.

Technical Specifications

• Nominal Size: 1 inch
• Material: Lead-free brass (per ASTM B584 or equivalent)
• Connection Type: Male NPT
• Application: Cold and hot water distribution systems, appliance hookups, general-purpose plumbing
