Schedule 80 CPVC Tees

Schedule 80 CPVC tees are critical components in high-pressure plumbing systems, designed to create a three-way junction for directing flow in various directions. Whether you're managing complex industrial piping or a residential repair, these fittings help create secure branch lines and reduce flow across systems.

Made from CPVC (chlorinated polyvinyl chloride), these tees offer higher pressure and higher temperature tolerance than Schedule 40 fittings due to their thicker walls. With ratings up to 340 PSI at 73°F and maximum temperature performance around 200°F, Schedule 80 CPVC tees are ideal for demanding applications requiring long-lasting durability and superior chemical resistance.

This category includes a wide range of CPVC tee types, including standard and reducing tees in Slip x Slip, Slip x FPT, and FPT x FPT socket styles. Whether you're looking to integrate these tees into a full CPVC system or connect them to threaded valves and instrumentation, Maxx Supply offers a quality selection and fast shipping to meet your project demands.

Common Applications and Project Suitability

Schedule 80 CPVC tees are used in systems where high pressure and temperature resistance are required. Industries such as chemical processing, commercial plumbing, HVAC cooling systems, and irrigation rely on CPVC fittings for their performance under corrosive or hot environments.

These CPVC tee fittings are especially well-suited for:

  • Industrial water lines
  • Tankless water heaters
  • Water heaters in commercial buildings
  • Waste systems including garbage disposals (with proper transition fittings)

Choose standard tees to split a pipe into equal flow directions or reducing tees when transitioning between different pipe sizes—common in branch lines sized ½”, ¾”, and 1”.

Sizing & Configuration Guide

Selecting the right CPVC tee starts with understanding the socket type and size compatibility:

  • Slip x Slip: Used for glue-in applications within full CPVC systems.
  • Slip x FPT / FPT x FPT: Ideal for connecting to threaded metal or plastic components such as valves, pumps, or instruments.

Make sure to match the nominal pipe size and consider temperature derating for higher-temperature water systems. For example, while a tee may be rated at 340 PSI at 73°F, pressure tolerance decreases as temperatures approach 200°F.

Available in a wide range of sizes, these CPVC fittings are easy to order online through Maxx Supply’s streamlined checkout process.

Schedule 80 CPVC Tee Installation Tips

Proper installation of CPVC tees ensures long-term system performance and prevents common plumbing failures:

  1. Surface Prep: Clean and dry the pipe and socket before applying CPVC primer and solvent cement.
  2. Solvent Welding: Insert pipe fully into the fitting socket while rotating ⅞ turn. Hold until set.
  3. Threaded Joints: Use PTFE tape or thread sealant rated for CPVC; avoid over-torquing.
  4. Support & Alignment: Ensure the system is supported properly to prevent sagging near the tees. Misaligned branches are a common issue.
  5. Inspection & Maintenance: Periodically inspect joints for leaks, discoloration, or stress marks. Re-cement if needed.

By following these best practices, contractors and DIYers can confidently install CPVC tees in both residential and industrial projects.
