Bsc Preferred DIB55-2W Slip Joint Extension Tube 1.5x6 White

Product Description

The BSC PREFERRED DIB55-2W is a white slip-joint extension tube used in drain line assemblies beneath sinks and lavatories. It extends or completes a P-trap connection between the trap arm and the drain basket outlet. The tube ships complete with a slip-joint nut and washer, so no additional hardware is needed for a standard installation. At 1.5 inches in diameter and 6 inches in length, it fits the most common residential sink drain configuration. Plumbers and plumbing contractors install this part during new rough-in work or as a replacement when existing drain lines are cracked, warped, or improperly sized.

This extension tube is suited for residential sink drain applications including kitchen sinks, bathroom lavatories, and utility sinks. It connects between a P-trap and the sink drain tailpiece or between trap components where additional straight run is required. The white finish coordinates with standard white plastic drain assemblies. The included nut and washer allow for a hand-tightenable slip-joint connection that remains serviceable for future access.

Installation Notes

A licensed plumber or qualified tradesperson should shut off water supply and clear standing water from the drain before beginning work. No special tools are required for slip-joint connections; hand-tightening the nut is standard practice, though channel-lock pliers may be used carefully to avoid overtightening and cracking the fitting. Installation should comply with applicable local plumbing codes and IPC guidelines for drain, waste, and vent systems. Inspect the washer seating before final tightening to ensure a leak-free connection.
