1-1/4 inch Lead-Free Brass Insert Elbow – 90° Barb Fitting for Potable Water Systems

The 1-1/4 inch Lead-Free Brass 90 Degree Insert Elbow is a PEX-compatible barb fitting designed to form a right-angle connection between two flexible tubing runs. Manufactured from lead-free brass in accordance with ANSI and ASTM specifications, this elbow supports cold and hot potable water applications and is suitable for both residential and commercial use.

Engineered for use with crimp or clamp ring systems, the fitting provides a secure mechanical seal when installed using ASTM F1807 or F2159 installation practices. It is intended for use in PEX water distribution systems where directional changes are needed within compact mechanical spaces.

Product Features

• ✅ Lead-Free Brass Alloy: Certified to NSF/ANSI 61 and 372 for use in potable water systems per federal regulations.
• ✅ Barbed Insert Design: Provides a secure grip inside PEX tubing when installed with properly sized copper crimp rings or stainless steel clamp bands.
• ✅ 90° Elbow Configuration: Facilitates directional transitions in confined areas without excessive pipe bending.
• ✅ Corrosion-Resistant Construction: Resists dezincification and oxidation in municipal and well water systems.
• ✅ Code-Compliant: Suitable for use in systems designed under IPC, UPC, and model plumbing codes recognizing ASTM F1807/F877 components.

Technical Specifications

• Nominal Size: 1-1/4 inch
• Material: Lead-Free Brass (C46500 or equivalent)
• Connection Type: Insert x Insert (Barb)
• Angle: 90 Degrees
• Standards: ASTM F1807, NSF/ANSI 61 & 372, ASME B1.20.1

Installation Guidelines

This fitting is designed for use with PEX tubing and should be installed using either copper crimp rings or stainless steel clamps, as specified by the system design. Tubing must be cut cleanly and inserted fully over the barbed ends. Ensure proper tool calibration for crimping or clamping to avoid seal failure. Do not use thread sealant; this is not a threaded fitting.

Typical Applications

Used in PEX water distribution systems for directional changes around structural framing, in manifolds, or during branch line transitions. Commonly found in residential builds, multi-unit housing, and light commercial plumbing systems requiring lead-free potable water components.

Regulatory Note

As of 2014, the U.S. Safe Drinking Water Act mandates that all fittings used in potable water systems must be lead-free. This fitting meets those criteria and is certified for use in compliant installations.

The 1-1/4 inch Lead-Free Brass Insert Elbow is a durable, code-approved solution for creating 90-degree transitions in PEX systems. Its mechanical reliability and corrosion-resistant construction make it a trusted component in both new construction and retrofit environments.
