Sioux Chief 23015 1-1/4" x 16" Double Slip Extension Tube

The Sioux Chief 23015 is a 1-1/4" x 16" double slip extension tube built for tubular drain waste rough-in and repair work beneath sinks, lavatories, and similar fixtures. This extension tube is available in Black and White finishes, giving the installer a color option to coordinate with the existing tubular waste assembly, and allows a plumber or contractor to extend or adjust the run of tubular waste piping between a trap and a fixture tailpiece or wall drain connection. It compensates for height and alignment differences encountered during installation or remodel work. Because both ends are open slip connections, the tube is intended to be joined using standard slip nuts and washers on each side, giving the installer flexibility to cut the tube to the exact length required on the job. This is a trade rough-in component, built for behind-the-fixture waste assembly rather than as a finished decorative part, and is suited to both residential and commercial applications.

Key Features

  • Trade Size: 1-1/4" x 16" double slip extension tube for tubular waste assemblies.

  • Color Options: Available in Black or White to match the surrounding tubular waste components.
  • Field-Cuttable Length: The 16" length can be trimmed on site to achieve the exact extension needed between fixture and drain connections.
  • Packaging: Packed 25 EA per bag, suited to stocking rough-in and service trucks or supply house inventory.
  • Country of Origin: Manufactured in Thailand.

Sioux Chief 230-461616125 – Frequently Asked Questions

1) Can the 16 inch extension tube be cut shorter on the job?
It's meant to be. The 16 inch length gives you stock to trim down to whatever drop you actually have between the fixture tailpiece and the trap or wall drain. Cut it square, deburr the end, and seat it under the slip nut and washer. Because neither end carries a flange, either end can be the cut end.
2) Do I need to buy slip nuts and washers separately for this extension tube?
Yes. The 23015 ships as the tube only, with open slip ends on both sides. Each joint needs a 1-1/4 inch slip nut and a matching slip joint washer, so plan on two sets unless you are reusing the nuts already on the trap and tailpiece.
3) What is a double slip extension tube used for under a sink?
It bridges the gap when the fixture outlet and the drain connection do not line up. On a remodel or a service call where the trap sits too low for the tailpiece, or the wall stub is off in height, the extension tube adds length to the tubular waste run. Both ends being slip means you set the insertion depth at each joint rather than being locked to a fixed dimension, which is how you take up misalignment. A tailpiece with a flange or a threaded end is the wrong part for that job, since it fixes one end of the run.
4) Is this extension tube a finished part for an exposed sink installation?
No. The 23015 is a rough-in component for the waste assembly behind or beneath the fixture, not a decorative trim piece. For an exposed pedestal lavatory or a wall-hung sink where the trap and tube are visible, you want a finished brass or chrome tubular part instead.
5) How many extension tubes come in a bag of Sioux Chief 23015?
They're bagged 25 each, which is why this one tends to live on a service truck or in supply house stock rather than being bought as a single. For property maintenance crews turning multiple units, one bag covers a lot of lavatory and sink waste repairs.
