Sioux Chief 240 Double Slip Joint Extension Tube, Chrome 22GA

The Sioux Chief 240 is a double slip joint extension tube built for behind-the-wall tubular waste rough-in on sink and lavatory drain assemblies. This extension tube is available in sizes ranging from 1/4" x 16" to 1/2" x 16", fabricated from 22GA chrome-plated tubing, giving installers the reach needed to bridge long or offset trap-to-drain runs without cutting and re-threading shorter sections. Whichever size is selected, every option in the family shares the same 16" length, 22GA chrome-plated construction, and double slip joint configuration, making the 240 a straightforward rough-in component for plumbers stocking tubular brass/chrome fittings for P-trap and waste assemblies.

Key Features

  • Trade Size Range: Available from 1/4" x 16" to 1/2" x 16" extension length for tubular drain and waste connections, letting plumbers match the tube to the specific trap-to-drain reach required on the job.
  • Durable Construction: 22GA chrome-plated tubing across all sizes in the family, delivering a durable, finished appearance on exposed slip-joint runs that will be visible beneath the fixture.
  • Double Slip Joint Design: Connects at both ends with slip-joint nuts and washers to extend or adapt tubular waste assemblies, common to every size offered in this family.
  • Finish: Chrome plating on every size option for a clean, corrosion-resistant exposed surface.
  • Consistent Length: All sizes in the family share a 16" overall length, simplifying stocking decisions when the diameter is the only variable that changes job to job.
  • Rough-In Flexibility: Lets installers bridge long or offset drain runs without having to cut and re-thread shorter tubing sections, saving labor time on both new rough-in and repair calls.

Sioux Chief 240-465115C16 – Frequently Asked Questions

1) Will the Sioux Chief 240 let me reach an offset drain without cutting tubing?
That is what the 16 inch length is for. It bridges long or offset trap-to-drain runs on sink and lavatory waste assemblies so you are not splicing shorter sections together. Slip joints at both ends let you slide the tube in and out to dial in the exact reach before tightening.
2) Do I need to buy slip joint nuts and washers separately for the Sioux Chief 240 extension tube?
The 240 is a double slip joint tube, meaning both ends are plain tube made to seat under a slip-joint nut and washer. Plan on having the correct size nuts and washers on hand for each end unless you are reusing the ones already on the trap and tailpiece.
3) Can I use the Sioux Chief 240 extension tube on a P-trap assembly?
Yes. It is made for P-trap and tailpiece connection runs, dropping in between the trap and the drain or between the fixture tailpiece and the trap. Match the tube diameter to the existing tubular size on the assembly, since the 240 is offered in 1/4 x 16 inch and 1/2 x 16 inch only.
4) Is 22 gauge chrome tubing heavy enough for a commercial restroom lavatory?
The 240 is 22 gauge chrome-plated steel, which is standard-wall tubular waste material rather than heavy-wall brass. It holds up for typical residential and commercial lavatory and sink drain work. On high-abuse public restrooms where the exposed tube gets kicked or where a vandal-resistant assembly is specified, a heavier-wall brass tubular product is the better call.
5) If I stock both sizes of the Sioux Chief 240, what actually changes between them?
Only the diameter. Both the 1/4 x 16 inch and 1/2 x 16 inch share the 16 inch overall length, 22 gauge chrome-plated steel construction, and double slip joint ends, so stocking both covers two diameters without adding a second length or finish to the shelf.
