Cresline 19355 SIDR-7 Flexible Pipe 1-1/4 in 300 Ft 200 Psi

Product Description

The CRESLINE 19355 is a blue polyethylene flexible pipe rated for potable water and general underground service applications. Built to SIDR-7 dimensional standards, it carries a 200 psi pressure rating at 73.4 degrees F, making it a reliable choice for residential and light commercial water service lines. The 1-1/4 inch nominal size delivers an inside diameter of 1.38 inches and an outside diameter of 1.774 inches with a wall thickness of 0.197 inches. Each coil measures 300 feet, reducing the number of joints needed on longer runs. Licensed plumbers and water service contractors are the primary installers for this type of flexible polyethylene pipe.

This pipe is suited for buried water service lines running from the meter to the structure, irrigation mains, and rural water supply systems. The blue color is the recognized field identifier for potable water service pipe, aiding inspection and identification after installation. The SIDR-7 designation specifies the standard inside diameter ratio, which governs wall thickness relative to the inside diameter. It is commonly used in residential new construction, water service replacement projects, and agricultural water distribution where a continuous coil reduces the number of fittings required on a run.

Installation Notes

Installation of buried water service pipe must comply with local plumbing codes and IPC requirements for depth, bedding, and backfill material. Shut off the water main supply and depressurize the line before making any connections. Use fittings and clamps rated for SIDR-7 polyethylene pipe at the specified outside diameter. A licensed plumber should perform all water service connections, pressure testing, and final inspection.
