Sioux Chief P9793D 1-1/2" PVC Slip Joint Coupling

The Sioux Chief P9793D is a 1-1/2" PVC slip joint coupling built for connecting tubular drain and waste piping in rough-in plumbing work. Its PVC construction and slip-joint design let a plumber join two lengths of 1-1/2" tubular pipe without solvent welding, making it a practical fitting for both new drain assemblies and field repairs. As a Sioux Chief rough-in fitting, the P9793D is sized and configured for straightforward behind-the-wall or under-fixture installation where a clean, serviceable tubular connection is needed rather than a permanent solvent-welded joint. Stocking this coupling alongside matching 1-1/2" tubular pipe, P-traps, and tailpieces lets a plumber complete or repair a drain assembly without cutting into an existing solvent-welded line.

Key Features

  • Trade Size: 1-1/2" nominal size for joining matching 1-1/2" tubular drain or waste pipe sections.
  • PVC Construction: Lightweight PVC body sized for non-pressurized drain, waste, and tubular fitting applications rather than pressurized supply lines.
  • Slip Joint Design: Slides over adjoining tubular sections to form a mechanical connection, simplifying assembly and letting the joint be taken apart again for future service without cutting the pipe.
  • Coupling Configuration: Joins two straight runs of 1-1/2" tubular pipe in-line, a common requirement when extending, repairing, or splicing existing drain and waste lines.
  • Rough-In Fitting: Intended for use behind the wall or under the fixture as part of the drain assembly, not as a visible finished component.
  • Field-Serviceable Joint: The slip connection can be loosened and re-made when a drain line needs to be reworked, rather than requiring the pipe to be cut and re-glued.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Tubular Drain and Waste Line Connections
  • P-Trap and Tailpiece Assemblies
  • Lavatory and Sink Drain Assemblies
  • Residential and Commercial Rough-In Plumbing
  • New Construction and Remodel Drain Rough-In
  • Repair and Extension of Existing Drain Lines

Why Sioux Chief?

Sioux Chief supplies rough-in plumbing hardware for professional installers, and the P9793D slip joint coupling reflects that focus with straightforward PVC construction sized to match standard 1-1/2" tubular drain and waste piping. For plumbers and contractors stocking rough-in parts, a dedicated slip joint coupling like this one keeps drain and waste line connections simple to assemble, size correctly, and service later without relying on solvent welding for every joint in the assembly. Keeping a few of these couplings on the truck alongside matching tubular pipe helps a drain repair or rough-in job move along without a special trip for a fitting.

Sioux Chief P9793D – Frequently Asked Questions

1) Will the Sioux Chief P9793D coupling join two pieces of 1-1/2 inch tubular drain pipe without glue?
That's exactly what it's for. The P9793D is a 1-1/2 inch PVC slip joint coupling that slides over two adjoining tubular sections and seals mechanically, so no solvent welding is needed. The joint can be loosened later and re-made if the drain has to be reworked, instead of cutting and re-gluing pipe.
2) Can I use a 1-1/2 inch PVC slip joint coupling on a pressurized water supply line?
No. The P9793D is a drain, waste, and tubular fitting, and the PVC slip joint body is sized for non-pressurized service only. For supply work you need a pressure-rated fitting and connection method, not a tubular slip joint.
3) My sink drain line is 1-1/4 inch tubular. Does this Sioux Chief coupling fit it?
No, it won't. The P9793D is a 1-1/2 inch nominal coupling and both ends take 1-1/2 inch tubular pipe. For a 1-1/4 inch lavatory tailpiece or trap arm you need the 1-1/4 inch coupling, or a reducing fitting if you're stepping from 1-1/4 to 1-1/2.
4) Is a slip joint coupling or a solvent-weld coupling the better choice for repairing a drain line?
Depends on whether you'll ever need to open the joint again. A slip joint coupling like the P9793D gives a serviceable mechanical connection, so it's the practical pick under a fixture or where the line may get reworked, and it lets you splice without cutting into a glued run. A solvent-weld coupling makes a permanent joint and is the choice for concealed piping you never intend to disturb.
5) Where in a drain assembly does the Sioux Chief P9793D coupling get installed?
It goes in the concealed part of the assembly, behind the wall or under the fixture, joining two straight in-line runs of 1-1/2 inch tubular pipe. It is a rough-in fitting, not a finished trim piece, so it isn't meant to be left exposed on a visible trap or tailpiece under a cabinet-free sink.
6) What else should I stock with this coupling to finish a 1-1/2 inch drain repair?
Matching 1-1/2 inch tubular pipe, a P-trap, and tailpieces. The P9793D only splices two straight tubular runs in-line, so the trap, trap arm, and any slip nuts and washers for those joints come from the rest of the assembly. Keeping the coupling on the truck with that tubular stock is what lets you extend or repair a line without a trip back for a fitting.
