Cresline 19770 Flexible Polyethylene Pipe 1.5 in Sdr 9 Cts

Product Description

The CRESLINE 19770 is a flexible polyethylene water service pipe rated to SDR 9 standards and sized at 1.5 inches CTS (Copper Tube Size). It is manufactured from polyethylene and supplied in a 100-foot coil, making it well suited for underground water service line installations. SDR 9 construction provides consistent wall thickness relative to pipe diameter, delivering reliable pressure performance. This pipe meets ASTM D2737 and AWWA C901 requirements and carries NSF approval for potable water contact, confirming it is safe for drinking water service. Licensed plumbers and water service contractors are the primary installers of this product.

This pipe is used in residential and light commercial water service applications where a flexible, corrosion-resistant line is needed between the water main and the building entry point. Its flexibility allows it to follow grade changes and accommodate minor soil movement without rigid fittings at every bend. The 100-foot coil length covers most standard residential service run distances in a single continuous piece, reducing the number of joints in the ground. It is appropriate for direct burial in trenched installations.

Key Features

• Flexible polyethylene construction resists corrosion and is suitable for direct burial
• SDR 9 wall thickness rating for consistent pressure capacity relative to pipe diameter
• 1.5-inch CTS sizing is compatible with standard copper tube size fittings and connections
• 100-foot coil length minimizes underground joints on typical residential service runs
• NSF approved for potable water contact
• Meets ASTM D2737 and AWWA C901 standards

Compatibility

Designed for use as a potable water service line with standard CTS-compatible insert or compression fittings sized for 1.5-inch copper tube size pipe.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and AWWA C901 guidelines. Shut off the water main before making any connections to an active service line. Use only fittings rated for polyethylene CTS pipe at the applicable pressure and temperature conditions. Avoid kinking the coil during handling and maintain the manufacturer-recommended bend radius throughout the run.
