1/2 inch Brass Insert Adapter Lead-Free Insert x Male

1/2 Inch Lead-Free Brass Insert Adapter – Insert x Male NPT

The 1/2 inch Brass Insert Adapter (Insert x Male NPT) is a transition fitting used for connecting polyethylene (PE) flexible tubing to standard NPT-threaded pipe systems. Manufactured from lead-free brass, this adapter is suitable for cold potable water and irrigation systems, and complies with applicable low-lead legislation for drinking water components.

Material and Performance Specifications

• Material: Lead-free brass (compliant with NSF/ANSI 61 and NSF 372)
• End Connections: 1/2 inch barbed insert end x 1/2 inch male NPT
• Compatible Tubing: CTS and IPS polyethylene (PE) or polybutylene tubing, depending on local code and insert clamp system
• Maximum Working Pressure: 150 PSI at 73°F (subject to tubing specifications)
• Temperature Range: 33°F to 120°F typical for cold water applications

Installation Requirements

The insert end is designed for use with stainless steel clamps or copper crimp rings. A uniform clamp force must be applied over the barbed area to ensure secure engagement with the tubing. The male NPT thread must be properly sealed using thread sealant or PTFE tape to ensure leak resistance at the connection point.

Applications

This fitting is commonly used in:

• Cold potable water supply systems (non-heated lines)
• Municipal and residential irrigation systems
• Rural water distribution where flexible poly tubing is utilized
• Trickle and sprinkler system transitions

Code Compliance Notes

This fitting meets lead-free compliance under the Safe Drinking Water Act (SDWA) and is approved for use in systems requiring NSF/ANSI 61 certified components. Always verify compatibility with local plumbing codes and tubing dimensions before installation.

The 1/2 inch Brass Insert Adapter Insert x Male NPT is a durable, corrosion-resistant fitting intended for use in pressurized cold water systems where flexibility and standard threaded transitions are required. Its lead-free construction supports code compliance and long-term mechanical reliability.
