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

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.

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.
