Philmac CTS-OD Compression Coupling with Stop | ASTM D2737

The Philmac CTS-OD Compression Coupling with Stop provides a secure and dependable way to connect two sections of CTS-OD polyethylene water pipe. Designed for Copper Tube Size Outside Diameter (CTS-OD) polyethylene pipe manufactured to ASTM D2737, this compression fitting is ideal for joining HDPE water lines in agricultural, livestock watering, and farm water distribution systems.

Featuring an internal pipe stop, this coupling helps position both pipe ends correctly during installation, creating a consistent connection between two sections of polyethylene pipe.

Philmac compression fittings allow for straightforward installation without specialized heat fusion or welding equipment, making them a practical solution for new water system installations, pipe extensions, and water line connections.

Important Compatibility Information

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

CTS-OD pipe uses 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.

The internal pipe stop makes this fitting suitable for joining two pipe sections but may limit its use for certain pipe repairs where a slip-style repair coupling without a stop is required.
