1 inch PEX Brass Insert Tee Crimp x Crimp x Crimp

1" Lead-Free Brass PEX Crimp Tee – Built for Performance in High-Demand PEX Installations

The 1" Lead-Free Brass PEX Crimp Tee provides a robust solution for creating three-way branches in PEX tubing systems. Designed for use in potable water distribution and hydronic applications, this tee conforms to ASTM F1807 standards and supports secure mechanical connections using crimp ring or clamp techniques. The fitting is manufactured from lead-free brass that meets NSF/ANSI 61 and 372 requirements, making it suitable for installations requiring full regulatory compliance.

Its durable construction and consistent dimensional tolerances allow for reliable sealing under thermal expansion, system vibration, and pressure fluctuations—critical for both new construction and complex retrofit environments.

Key Technical Features

• ✅ Lead-Free Brass Construction – Compliant with ≤0.25% lead content for use in potable water systems under current U.S. plumbing codes.
• ✅ Three-Port Configuration – Allows for balanced fluid distribution from main supply lines to branch circuits or fixtures.
• ✅ Precision Barbed Inserts – Machined to tight tolerances for consistent crimp engagement and reduced risk of leakage.
• ✅ Corrosion-Resistant Material – Suitable for chlorinated water and high-humidity mechanical environments.
• ✅ Standardized Crimp Compatibility – Works with copper crimp rings, stainless steel clamps, and approved ASTM F1807 tools.

Specifications

• Material: Lead-Free Brass
• Nominal Size: 1 inch
• Connection Type: ASTM F1807 Crimp (PEX x PEX x PEX)
• Certifications: NSF/ANSI 61, NSF/ANSI 372, ASTM F1807
• Pressure Rating: 160 PSI at 73°F / 100 PSI at 180°F

Installation Guidelines

Proper installation requires use of calibrated crimp tools and verification of crimp integrity using go/no-go gauges. Pipe ends should be square-cut and free of burrs. Ensure full insertion of each PEX tube and position the crimp ring 1/8"–1/4" from the end of the tube prior to compression. Verify that each connection is secure before conducting system pressure tests.

Application Areas

Commonly deployed in residential and light commercial PEX systems, this tee fitting is suitable for manifold-fed supply lines, utility room transitions, and fixture branch connections. It performs well in both pressurized potable water and closed-loop heating circuits.

Material Note

Brass fittings offer high resistance to dezincification and thermal fatigue. Lead-free variants are now required under federal law for all drinking water applications, making this tee a code-compliant option for all U.S. jurisdictions.

Summary

The 1" Lead-Free Brass PEX Crimp Tee delivers dependable mechanical performance and system compatibility in PEX installations that require three-way branching. Its lead-free certification, material integrity, and ease of installation make it a trusted solution for professionals working in code-governed plumbing systems.
