1 Inch Brass Insert Adapter – Lead-Free, Insert x Male NPT for Polyethylene Tubing

The 1 inch brass insert adapter features a barbed insert connection on one end and a male NPT thread on the other. It is designed for use with polyethylene (PE) tubing in cold water distribution systems, irrigation lines, and utility piping. The fitting provides a secure mechanical connection when installed with stainless steel hose clamps and is suitable for underground or above-ground applications when installed in accordance with code requirements.

Material Specifications and Compliance

This adapter is manufactured from lead-free brass compliant with federal regulations for potable water use. It meets ANSI/NSF 61 and 372 standards for drinking water system components and conforms to dimensional and performance standards for insert fittings used in polyethylene water service lines.

• ✅ Material: Lead-Free Brass (typically UNS C46500 or C69300)
• ✅ Connection Type: 1 inch insert (barbed) x 1 inch male NPT
• ✅ Standards: ASTM D2609 (insert fittings), ANSI/NSF 61 & 372
• ✅ Pressure Rating: Up to 200 psi (dependent on system configuration and pipe type)

Installation Guidelines

Install the insert end into IPS-sized polyethylene tubing using approved stainless steel clamps or crimp bands. Ensure proper insertion depth and secure the clamp over the barbed section. The NPT male threaded end should be joined using thread sealant or PTFE tape. Do not overtighten to avoid thread damage or stress cracking. The fitting is suitable for direct burial if local code permits and proper corrosion mitigation measures are used.

Typical Applications

Used in cold potable water systems, irrigation supply lines, rural service connections, and yard hydrant installations. It provides a transition point between PE pipe and threaded valves, tees, or pressure regulators in both municipal and private water systems.

Code Note

Lead-free brass fittings are required for all potable water system components under the Safe Drinking Water Act. This adapter complies with applicable IPC, UPC, and state-specific plumbing codes when used in approved service applications.
