3/4 inch PEX Brass Insert Tee Crimp x Crimp x Crimp

3/4 inch Lead-Free PEX Crimp Tee – Manufactured for Code-Compliant PEX Distribution Systems

The 3/4 inch Lead-Free PEX Crimp Tee is a mechanically robust fitting designed for branching cross-linked polyethylene (PEX) tubing in potable water or hydronic applications. This component conforms to ASTM F1807 standards and is manufactured from lead-free brass in accordance with NSF/ANSI 61 and 372 requirements. Its crimp-style connections provide a secure, permanent seal suitable for high-pressure systems across a variety of installations.

Engineered for use in new construction and retrofit scenarios, this tee supports three-way directional flow in PEX tubing layouts, allowing for efficient distribution from supply mains to branch lines in both residential and commercial environments.

Product Features

• ✅ Forged Lead-Free Brass Body – Meets federal requirements for ≤0.25% weighted lead content, ensuring potable water system compliance.
• ✅ ASTM F1807 Designation – Compatible with Type A and Type B PEX using crimp rings or stainless steel clamps.
• ✅ High-Cycle Durability – Resistant to dezincification, corrosion, and thermal fatigue in closed-loop and pressurized water systems.
• ✅ Standard 3-Port Tee Configuration – Designed for balanced flow distribution to lateral runs and return lines.
• ✅ Consistent Crimp Engagement – Precision-machined barbs ensure uniform compression during installation with properly calibrated crimp tools.

Installation Guidance

This fitting is installed using copper crimp rings or stainless steel clamps with manufacturer-approved crimp tools. Ensure all PEX tubing is cut square, deburred, and fully seated prior to securing. Crimp ring alignment and calibration of the tool are critical to ensuring a leak-free joint. Installers should verify with a go/no-go gauge post-crimp before proceeding with pressure testing.

Application Use

Ideal for integration into manifold-fed systems, riser branches, and horizontal distribution networks. Frequently used in high-density residential and light commercial environments where PEX systems are preferred for efficiency and thermal resilience. Suitable for both hot and cold water distribution systems under continuous use conditions.

Code Compliance Note

Federal and state plumbing codes require the use of lead-free components in potable water systems. This tee meets all current compliance standards and is certified for use across all 50 U.S. states.

Summary

The 3/4 inch Lead-Free PEX Crimp Tee provides a stable, corrosion-resistant branch connection point in PEX distribution systems. Its forged brass construction and ASTM-compliant design make it a reliable solution for long-term service in pressure-rated plumbing networks.
