3/4 inch CPVC 90 Degree Elbow Plastic x Plastic

3/4” CPVC 90° Elbow – Schedule 80 Socket Fitting for Hot and Cold Water Distribution

The 3/4-inch CPVC 90-degree elbow is designed for use in chlorinated polyvinyl chloride (CPVC) piping systems requiring a sharp directional change. This socket-style fitting enables solvent-weld connections in Schedule 80 CPVC systems and is commonly used in both hot and cold potable water distribution, as well as in light commercial and industrial process piping.

Molded from CPVC Type IV, Grade 1 compound (cell classification 23447 per ASTM D1784), this fitting is engineered to maintain dimensional integrity under elevated pressure and temperature conditions. It meets the requirements of ASTM F439 for Schedule 80 CPVC fittings and is certified for potable water use.

Technical Specifications

• Nominal Size: 3/4 inch
• Connection Type: Socket x Socket (solvent weld)
• Material: CPVC Type IV, Grade 1 (Cell Class 23447)
• Angle: 90 degrees
• Standard Compliance: ASTM F439 (fitting), NSF/ANSI 61 and 372 (potable water), ASME B16.5 dimensional compatibility
• Maximum Service Temperature: 200°F (93°C) at derated pressure

Performance Features

• ✅ Thermal and Pressure Stability – Suitable for use in systems handling domestic hot water or low-pressure chemical fluids
• ✅ Corrosion-Resistant – Inert to most chlorinated and mildly acidic environments
• ✅ Lightweight and Rigid – Easier to install and align than metallic systems in suspended or concealed runs
• ✅ Low Thermal Conductivity – Reduces heat loss and sweating in chilled or hot water systems

Installation Considerations

All joints must be prepared using a CPVC-compatible primer and solvent cement meeting ASTM F493. Pipe ends should be square-cut, chamfered, and thoroughly cleaned before assembly. Allow for full cure time before hydrostatic testing or exposure to system pressures. Do not use for compressed air or gas systems.

Common Applications

This elbow is typically used in hot and cold water lines for residential, institutional, and light commercial plumbing systems. It is also suitable for some industrial fluid transport applications where temperature and chemical compatibility are within design limits.

Material Note

CPVC piping systems are favored in environments requiring corrosion resistance, ease of installation, and extended service life. Their resistance to scaling and biofilm makes them suitable for potable water systems, particularly in retrofit or confined-space installations.

The 3/4” CPVC 90° elbow provides a code-compliant, solvent-welded transition in CPVC piping networks where directional changes must maintain hydraulic integrity and pressure rating consistency.
