1-1/4 inch CPVC CTS 45 Degree Elbow CTS x CTS

1-1/4 inch CPVC 45° Elbow – Chlorinated Polyvinyl Chloride Fitting for Directional Changes

The 1-1/4 inch CPVC 45 Degree Elbow is a molded thermoplastic fitting designed to provide a smooth directional offset in CPVC piping systems. Manufactured from CPVC Type IV, Grade 1 material (ASTM D1784, Cell Classification 23447), it offers excellent mechanical strength, chemical resistance, and thermal stability for use in both hot and cold water pressure systems.

Engineered to meet the dimensional requirements of ASTM D2846 or ASTM F439 (depending on system type), this elbow features socket ends for solvent cement welding, allowing for uniform bonding and consistent joint integrity in high-temperature applications such as potable water distribution and hydronic piping systems.

Performance Characteristics

• ✅ Material: CPVC (Chlorinated Polyvinyl Chloride), formulated for hot and cold potable water systems per ASTM D1784.
• ✅ Angle: 45° bend designed to minimize hydraulic losses compared to 90° elbows in directional changes.
• ✅ Joining Method: Solvent cement welds provide leak-resistant, chemically fused joints without the need for threading.
• ✅ Temperature Rating: Rated for continuous service up to 200°F (93°C) under pressure when used with CPVC SDR or Schedule 80 systems.
• ✅ Standards Compliance: Manufactured in accordance with ASTM D2846 (SDR 11) or ASTM F439 (Schedule 80), depending on system type.

Installation Guidelines

Clean, dry, and deburr all pipe ends prior to insertion. Apply CPVC solvent cement and primer in accordance with ASTM F402 and the cement manufacturer’s instructions. Allow for proper set and cure time before system pressurization. Ensure joints are not under stress during cure period to avoid hairline cracks or failures. Use with Schedule 80 or SDR-11 CPVC systems as specified by project design.

Common Applications

Used in hot and cold potable water distribution systems, recirculating plumbing loops, and commercial piping systems requiring compact directional transitions. The 45° geometry is often utilized to reduce fluid resistance and water hammer potential in horizontal runs or offset configurations.

Regulatory Compliance

CPVC fittings meet applicable IPC, UPC, and NSF requirements for use in potable water systems. This fitting complies with NSF/ANSI 61 and 372 for lead-free plumbing and is approved for use in systems subject to the Safe Drinking Water Act.
