CPVC Pipe & Fittings

CPVC Pipe & Fittings are a reliable, code-compliant choice for hot and cold water distribution in homes and light commercial projects. Made from chlorinated polyvinyl chloride, CPVC resists corrosion, pitting, and scale, and maintains pressure integrity at elevated temperatures. For potable water, look for NSF-certified products and markings like CTS (copper tube size) SDR 11 or Schedule 80 for higher-pressure, industrial needs.

Benefits include quick, clean installation, lighter weight than copper, and quiet operation. Solvent-weld joints use CPVC-specific cement (often yellow or orange) and, where required, primer; do not substitute PVC cement. Typical ratings are 400 psi at 73°F and 100 psi at 180°F, making CPVC suitable for water heaters and recirculation lines within manufacturer limits.

Common fittings include elbows, tees, couplings, caps, unions, and transition adapters to brass or galvanized. Use CPVC-to-metal transition fittings to avoid stress cracking; apply PTFE thread sealant (not tape-heavy) on metal threads and hand-tighten plus a quarter turn.

Installation tips include:
- Cut square with a fine-tooth saw or ratcheting cutter and deburr/ream the ID.
- Dry-fit for alignment, then apply cement fully around pipe and socket.
- Insert with a quarter-turn and hold for 10–30 seconds to prevent push-back.
- Wipe excess, allow proper cure time by temperature, pipe size, and humidity.
- Support horizontals per manufacturer spacing, protect from UV or insulate as needed.

CPVC stands out against copper and PEX with strong chlorine resistance, low thermal conductivity, and competitive cost. It is a dependable choice for re-pipes, new construction, and repairs. Shop pipes, fittings, valves, hangers, solvent cement, primer, cutters, and test plugs to build a complete CPVC plumbing system that passes inspection and performs for decades. Choose sizes from 1/2 in. to 2 in. CTS, or IPS Schedule 80 where specified, and verify compliance with ASTM D2846, F441, F438. Store pipe properly and keep ends clean.
