CPVC 45° Elbow – Socket x Socket Fitting for Hot and Cold Water Distribution

The CPVC 45-Degree Elbow is a socket-style fitting used in chlorinated polyvinyl chloride (CPVC) piping systems to change direction by 45 degrees. It allows for smooth directional transitions while maintaining consistent flow characteristics in pressure-rated potable water systems. This fitting is designed for solvent cement installation and is compatible with SDR 11 and CTS (Copper Tube Size) CPVC piping.

Manufactured from CPVC Type IV, Grade 1 compound as per ASTM D1784 (Cell Classification 23447), the elbow offers superior mechanical strength and high-temperature performance. It meets all applicable standards for use in hot and cold water distribution systems in both residential and commercial installations.

Performance and Material Specifications

• ✅ Material: CPVC 4120 – Chlorinated polyvinyl chloride, rated for continuous service at elevated temperatures.
• ✅ Size: Typically available in 1/2" through 2" CTS sizes; this specification assumes standard CTS dimensioning.
• ✅ Configuration: Socket x Socket (Slip x Slip), for solvent weld joining with CPVC tubing.
• ✅ Temperature Rating: Rated for 100 PSI at 180°F and 400 PSI at 73°F, per ASTM D2846 for hot and cold water distribution.
• ✅ Compliance: NSF/ANSI 61 and NSF/ANSI 14 certified; compliant with UPC and IPC code requirements for potable systems.

Installation Guidelines

This fitting must be installed using CPVC-compatible primer and solvent cement per manufacturer recommendations. Ends should be square-cut, deburred, and dry-fitted prior to assembly. Ensure appropriate cure times based on ambient temperature and pipe size. Do not subject the joint to pressure before full cure. All installation must comply with local plumbing codes and ASTM D2855 solvent-welding procedures.

Common Applications

The 45-degree CPVC elbow is commonly used in hot and cold potable water lines, recirculating domestic water systems, and low-pressure hydronic piping layouts. It is ideal for configurations where space constraints require gradual directional changes to minimize hydraulic loss or mechanical strain on fittings.

Material Insight

CPVC is chemically resistant and capable of handling continuous hot water exposure, unlike standard PVC. Its thermal stability makes it suitable for use in systems requiring sustained temperatures up to 180°F. All CPVC fittings for potable use must be certified lead-free under federal Safe Drinking Water Act regulations.
