Philmac CTS-OD Compression Male Adapter | ASTM D2737

The Philmac CTS-OD Compression Male Adapter provides a secure and dependable connection between CTS-OD polyethylene water pipe and female-threaded plumbing fittings. Designed for Copper Tube Size Outside Diameter (CTS-OD) polyethylene pipe manufactured to ASTM D2737, this adapter allows HDPE water lines to connect directly to compatible threaded valves, fittings, and water distribution equipment.

Featuring a compression connection on one end and male pipe threads on the other, this fitting makes it easy to transition from polyethylene pipe to threaded plumbing components without specialized heat fusion or welding equipment.

Ideal for livestock watering systems, rotational grazing setups, agricultural irrigation, and farm water distribution, Philmac CTS-OD male adapters provide a practical solution for connecting HDPE pipe to water tanks, shutoff valves, manifolds, and other compatible plumbing components.

Whether you're installing a new livestock watering system or modifying an existing water line, this adapter provides a convenient connection between CTS-OD polyethylene pipe and female-threaded fittings.

What Is a CTS-OD Compression Male Adapter Used For?

A compression male adapter allows polyethylene water pipe to connect to plumbing components that have female pipe threads.

For example, a livestock watering system may use HDPE pipe to transport water from a main supply line to a water tank. A Philmac CTS-OD male adapter can provide the transition from the polyethylene pipe to a compatible female-threaded valve or fitting.

These adapters are also useful when connecting water lines to distribution manifolds, shutoff valves, and other threaded plumbing equipment.

Reducing male adapters allow a larger CTS-OD polyethylene pipe to connect to a smaller threaded opening, eliminating the need for additional reducing fittings in certain installations.

Important Compatibility Information

This male adapter 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.

The compression end connects to CTS-OD polyethylene pipe, while the male-threaded end connects to a compatible female-threaded plumbing fitting.

Verify the thread type and size before installation. Use an appropriate thread sealant approved for the fitting material and application, following the manufacturer's installation recommendations.
