Bsc Preferred DIB66-13W Plastic Wall Tube 1-1/2 X 7 Inch

Product Description

The BSC PREFERRED DIB66-13W is a plastic wall tube designed for tubular drain applications in residential and light commercial plumbing systems. Measuring 1-1/2 inches in diameter and 7 inches in length, this wall tube provides a clean, finished pass-through point where a drain line exits through a wall or cabinet panel. Its plastic construction resists corrosion and moisture, making it well suited for under-sink and vanity installations. Licensed plumbers and experienced DIYers install this component as part of standard P-trap and drain assembly setups. The lightweight design and straightforward fit simplify installation and reduce labor time on routine drain service calls.

This wall tube is used in tubular drain assemblies where the drain line transitions through a finished wall surface or cabinet back. Typical applications include bathroom vanity sink drains, kitchen sink drain passes, and utility sink setups. It is commonly installed alongside P-traps, tailpieces, and slip-joint drain fittings as part of a complete under-sink drain system. The 1-1/2 inch diameter is the standard size for residential lavatory and kitchen drain lines, making this tube a common service and replacement item on routine plumbing calls.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson following applicable IPC and local plumbing code requirements. Shut off the water supply and ensure the drain line is clear before beginning work. No special tools are required beyond standard slip-joint pliers for securing adjacent fittings. Avoid over-tightening slip-joint nuts on plastic fittings, as this can cause cracking or deformation.
