Bsc Preferred DIB812-6 Flex Extension Tube 1-1/2 in

Product Description

The BSC PREFERRED DIB812-6 is a 1-1/2 inch flexible extension tube designed for slip-joint drain connections in plumbing applications. The flexible body accommodates pipe misalignment and simplifies installation in tight or awkward spaces where rigid tubing would be difficult to seat correctly. Compatible with both plastic and brass slip-joint fittings, this extension tube is a practical solution for drain line work under sinks and similar fixtures. Licensed plumbers and experienced DIYers alike use this type of fitting to complete trap-to-drain connections quickly and cleanly.

This extension tube is suited for residential and light commercial plumbing drain applications, particularly under-sink installations where the drain outlet and trap require an adjustable connection. The flexible construction allows the tube to bend slightly to meet misaligned inlets without additional fittings or offsets. Its slip-joint design means no solvent cement or threaded connections are required for assembly.

Key Features

• Flexible body accommodates pipe misalignment and simplifies rough-in fitting
• Slip-joint connection for tool-light assembly and easy disassembly during service
• Compatible with plastic and brass slip-joint drain systems

Compatibility

Designed as an OEM-style replacement or new-install extension tube compatible with 1-1/2 inch slip-joint plastic and brass drain assemblies commonly found in residential and light commercial sink drain systems.

Installation Notes

Installation is typically performed by a licensed plumber or qualified tradesperson. Shut off water supply and clear standing water from the drain line before beginning work. Hand-tighten slip-joint nuts to seat washers properly, then snug with pliers — avoid over-tightening, which can crack plastic nuts or distort washers. Verify alignment and check for leaks after restoring water flow.
