Sharkbite U870R300 Red Pex-b Coil 3/4 in Cts 300 Ft

Product Description

The SharkBite U870R300 is a 300-foot coil of 3/4-inch CTS red PEX-B cross-linked polyethylene tubing designed for residential and commercial potable water distribution systems. The tubing is printed with SharkBite's repeating imprint pattern, which gives installers a clear visual reference to confirm full tube insertion into SharkBite push-fit fittings. At 50 pounds per coil, this is a production-quantity supply run suitable for new construction rough-in or full system repiping. The red color coding follows standard convention for hot-side water lines, making rough-in identification straightforward on the job site.

This tubing is used in residential and light commercial plumbing systems for hot and cold potable water supply runs. It is well suited for radiant heating distribution, manifold-based home-run systems, and traditional trunk-and-branch layouts. The 3/4-inch CTS sizing is the standard main distribution size in most residential systems, feeding branch lines to fixtures and appliances. It is installed by licensed plumbers and pipefitters working under applicable plumbing codes.

Key Features

• Cross-linked polyethylene (PEX-B) construction rated for potable water service
• Red color coding identifies hot-side supply lines at a glance
• SharkBite imprint pattern confirms full tube insertion into push-fit fittings
• 3/4-inch Copper Tube Size (CTS) for compatibility with standard CTS fittings and valves
• 300-foot coil minimizes joints on long runs, reducing potential leak points

Compatibility

Designed for use with SharkBite push-fit fittings and other standard CTS-compatible PEX fittings. Suitable for potable water supply applications where 3/4-inch PEX-B tubing is specified.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before cutting into any existing system. Use a dedicated PEX tube cutter to ensure a clean, square cut before inserting into push-fit or crimp fittings. Follow minimum bend-radius requirements to avoid kinking the tubing during rough-in.
