Philmac CTS-OD Compression Female Elbow | ASTM D2737

The Philmac CTS-OD Compression Female Elbow provides a secure and dependable way to connect CTS-OD polyethylene water pipe to male-threaded plumbing fittings while creating a 90-degree change in direction. Designed for Copper Tube Size Outside Diameter (CTS-OD) polyethylene pipe manufactured to ASTM D2737, this fitting provides a convenient transition between HDPE water lines and threaded water distribution components.

Featuring a compression connection on one end and a female-threaded connection on the other, this 90-degree elbow allows polyethylene water lines to connect to compatible male-threaded valves, fittings, and water supply equipment without requiring additional elbows or adapters.

Ideal for livestock watering systems, rotational and regenerative grazing setups, agricultural irrigation, and farm water distribution, Philmac CTS-OD female elbows provide a practical solution for directing water lines toward livestock water tanks, valves, manifolds, and other plumbing connections.

Whether you're installing a new livestock watering system or modifying an existing HDPE water line, this fitting provides a convenient way to change pipe direction while transitioning to a threaded connection.

What Is a CTS-OD Compression Female Elbow Used For?

A compression female elbow allows polyethylene water pipe to make a 90-degree turn while connecting directly to plumbing components with male pipe threads.

For example, a livestock watering system may use HDPE pipe to transport water from a main supply line to a livestock water tank. A Philmac CTS-OD Compression Female Elbow provides the transition from the polyethylene pipe to a compatible male-threaded valve or fitting while changing the direction of the water line.

These fittings are also useful when connecting water lines to threaded manifolds, water supply connections, and other plumbing equipment where a 90-degree turn is required.

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

Important Compatibility Information

This female elbow 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 female-threaded end connects to a compatible male-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.
