1 inch PEX Stainless Steel Insert Tee PEX x PEX x PEX

1 inch PEX Stainless Steel Insert Tee – For Full-Size PEX Branching and Distribution

The 1 inch PEX stainless steel insert tee is a triple-barb fitting designed to connect three 1 inch PEX lines in a T-configuration. This component is engineered for use in pressure-rated potable water and hydronic systems, enabling the extension of main lines or creation of branch circuits in high-flow environments.

Technical Specifications

• Material: 304 stainless steel – corrosion-resistant and mechanically durable
• Connection Type: 1 inch PEX barb x 1 inch PEX barb x 1 inch PEX barb
• System Compatibility: Suitable for ASTM F1807 and F2098 crimp or clamp ring connections
• Working Pressure: Rated for 200 PSI at 73°F; suitable for systems operating up to 200°F
• Certifications: Lead-free certified per NSF/ANSI 61 and 372 for potable water applications

Applications

Typically installed in residential and light commercial systems for hot and cold water distribution. Ideal for use in trunk-and-branch layouts, radiant heating loops, and direct-run configurations where full-size branches are required from a main line.

Installation Requirements

Ensure square, burr-free cuts on PEX tubing. Insert tubing fully over each barb and secure using properly calibrated crimp or clamp tools. This is a mechanical insert connection—no thread sealant or plumber’s tape is required. Perform system pressure testing per code to validate connection integrity.

Performance Consideration

Stainless steel insert fittings offer high mechanical strength and resistance to dezincification in aggressive water conditions. Their dimensional stability and corrosion resistance provide a longer service life compared to brass alternatives in variable system environments.
