3/4 inch PEX Engineered Plastic 90 Degree Insert Elbow PEX x PEX

3/4" PEX x 3/4" PEX Elbow – Designed for Secure Directional Transitions

The 3/4" PEX x 3/4" PEX elbow is a critical component for directional changes in cross-linked polyethylene (PEX) plumbing systems. Engineered for use in both residential and commercial applications, this insert-style fitting allows for efficient 90-degree pipe redirection while maintaining flow integrity.

Manufactured from high-strength brass or polymer (depending on model), it complies with ASTM F1807 or F2159 standards for insert fittings. This elbow is compatible with crimp, clamp, or expansion ring connection methods, depending on the fitting material and system design.

Key Performance Advantages

• ✅ Durable Construction Built for pressure-rated potable water distribution systems with long-term reliability.
• ✅ Secure Insert Connection Designed for optimal grip with PEX tubing when used with crimp or clamp rings.
• ✅ Thermal Resistance Performs effectively in both hot and cold water systems without compromising structural integrity.
• ✅ Code-Compliant Certified to UPC, NSF/ANSI 61, and CSA standards where applicable.

Technical Specifications

• Connection Type: Insert x Insert (PEX)
• Material: Forged brass or high-performance engineered polymer (model dependent)
• Nominal Size: 3/4 inch x 3/4 inch
• Conformance: ASTM F1807 (brass) or ASTM F2159 (polymer)

Installation Guidelines

Install using compatible crimp rings (ASTM F1807/F2159), stainless steel cinch clamps (ASTM F2098), or expansion fittings (ASTM F1960) as appropriate. Ensure tubing is fully inserted and properly aligned before securing the joint. Confirm ring placement and verify that all tools are calibrated and approved for the connection type being used.

Typical Applications

This elbow is commonly used in potable water systems, radiant heating loops, and hydronic piping assemblies. It is ideal for confined runs where bending radius limitations require a rigid angled fitting to maintain flow path without kinking the pipe.

Note on Material Selection

When selecting between brass and polymer elbows, consider factors such as water quality, system pressure, and local code requirements. Brass fittings are often preferred for high-temperature or high-pressure systems, while polymer options offer excellent corrosion resistance and thermal stability in non-metallic installations.

The 3/4" PEX elbow provides the directional reliability and pressure performance required by plumbing professionals. Whether you're working on distribution manifolds, lateral branch runs, or mechanical room assemblies, this fitting delivers consistent performance where precision counts.
