Philmac CTS-OD Compression Tee | ASTM D2737

The Philmac CTS-OD Compression Tee provides a secure and dependable way to create a branch connection in CTS-OD polyethylene water pipe. Designed for Copper Tube Size Outside Diameter (CTS-OD) polyethylene pipe manufactured to ASTM D2737, this three-way compression fitting allows water to be distributed from a main HDPE water line to additional supply lines.

Ideal for livestock watering systems, rotational and regenerative grazing setups, agricultural irrigation, and farm water distribution, this compression tee makes it easy to expand an existing water system or create multiple water supply connections.

Featuring three compression connections, the Philmac CTS-OD tee connects compatible polyethylene pipes without requiring heat fusion, welding, or specialized fusion equipment.

Whether you're installing a new livestock watering system, adding water access to another paddock, or expanding an existing HDPE water distribution network, this compression tee provides a practical solution for branching water lines.

What Is a CTS-OD Compression Tee Used For?

A compression tee allows a single polyethylene water line to branch into two directions, creating an additional water supply connection.

For example, a livestock watering system may use a main HDPE water line running through several paddocks. A Philmac CTS-OD Compression Tee can be installed along that line to create a branch supplying another livestock water tank or watering location.

This allows farmers and ranchers to expand their water distribution systems without installing an entirely separate supply line from the original water source.

Compression tees are especially useful when designing rotational grazing systems where multiple paddocks require dependable access to water.

Important: When branching a water line to supply multiple watering locations, consider pipe diameter, available water pressure, elevation changes, and the total water demand. Proper pipe sizing helps maintain adequate flow throughout the system.

Important Compatibility Information

This compression tee is designed for CTS-OD polyethylene pipe (ASTM D2737).

CTS-OD pipe has different outside diameter dimensions than IPS-OD (ASTM D3035) and IPS-ID (SIDR ASTM D2239) polyethylene pipe.

Always verify your pipe's outside diameter and sizing standard before purchasing compression fittings.

All three openings feature compression connections for compatible CTS-OD polyethylene pipe.

For proper installation, ensure pipe ends are cut square, properly prepared, and inserted to the manufacturer's recommended depth. Follow Philmac's installation instructions for tightening and pressure testing.
