Sioux Chief 040 4" Slotted Polypropylene Cleanout Plug, Less Insert

The Sioux Chief 4" slotted cleanout plug is a white, reinforced polypropylene plug built for rough-in drain, waste, and vent (DWV) cleanout service. This plug is supplied less insert, meaning it does not include the threaded brass insert that some Sioux Chief cleanout plugs ship with - a straight polypropylene-to-polypropylene fit for jobs that do not call for a metal insert. The 4" slotted design allows installers to seat and seal the plug into a cleanout fitting body quickly on the jobsite, and the reinforced polypropylene construction resists the seizing that traditional plugs can experience when threaded into ABS or PVC cleanout bodies over time.

Key Features

  • Trade Size: 4" cleanout plug sized for standard 4" cleanout fitting bodies.
  • Durable Construction: Reinforced polypropylene material is chemical-resistant and more durable than traditional cleanout plug materials.
  • Won't Seize: Engineered so it will not seize up on ABS or PVC cleanout fittings, unlike many traditional plugs.
  • Slotted Design: Slotted head allows for straightforward installation and removal with a standard screwdriver-type tool.
  • Less Insert Configuration: Supplied without the threaded brass insert - a polypropylene-only plug for applications that do not require a brass-threaded opening.
  • Color: White polypropylene finish for standard DWV cleanout applications.

Technical Specifications

  • Country of Origin: United States
  • Cubic Volume: 0.381475
  • Packaging: 25 EA per case

Typical Applications

  • Residential and Commercial Rough-In Plumbing
  • Drain, Waste, and Vent (DWV) Cleanout Access Points
  • ABS and PVC Cleanout Fitting Assemblies
  • New Construction and Renovation Plumbing Projects

Why Sioux Chief?

Sioux Chief builds this 4" cleanout plug from reinforced polypropylene specifically so it resists seizing against ABS or PVC cleanout bodies - a common failure point with lower-grade plugs after repeated exposure. The chemical-resistant material and slotted design give plumbers and contractors a durable, easy-to-service cleanout plug for behind-the-wall and under-slab DWV rough-in work.

Sioux Chief 878-040 – Frequently Asked Questions

1) Will the Sioux Chief 878-040 cleanout plug thread into a 4 inch ABS or PVC cleanout fitting without seizing?
That is the reason this plug exists. The 878-040 is reinforced polypropylene, and Sioux Chief builds it so it will not seize up against ABS or PVC cleanout bodies the way traditional plugs do after repeated exposure. It is sized for standard 4 inch cleanout fitting bodies, so it threads into a 4 inch ABS or PVC cleanout body and still backs out later when someone needs to rod the line.
2) What does "less insert" mean on the Sioux Chief 878-040 plug, and will I be missing a part?
Less insert means the plug ships without the threaded brass insert that some Sioux Chief cleanout plugs include. You get a straight polypropylene plug with nothing to add. Choose it when the job does not need a brass-threaded opening in the plug face. If your spec calls for a metal-threaded tapping in the plug, you want the version that comes with the insert instead, not the 878-040.
3) How do you install and remove a slotted cleanout plug like this one?
The head is slotted, so it seats and backs out with a standard screwdriver-type tool or a bar laid across the slot. No special wrench and no square nut to round off. That matters on service calls where the plug has been buried behind a wall or under slab for years, since polypropylene against ABS or PVC does not lock up the way a cast plug can.
4) Is a polypropylene cleanout plug durable enough for commercial DWV rough-in, or should I use a metal plug?
Reinforced polypropylene is chemical resistant and holds up in residential and commercial DWV rough-in, including behind-the-wall and under-slab cleanout access points. Where plastic wins over a metal plug is corrosion and seizing: it will not bond itself into an ABS or PVC cleanout body. Where a metal plug is still specified is an exposed, abuse-prone location or a job whose drawings call out a brass or cast plug by material.
5) How many Sioux Chief 878-040 plugs come in a case?
Packaging is 25 each per case. For a repair-and-maintenance crate or a tract-house rough-in, that is enough to cover a run of 4 inch cleanouts off one box. The plugs are white polypropylene, so they look consistent anywhere they stay visible.
6) Is the Sioux Chief 878-040 cleanout plug made in the USA?
Yes, country of origin on the 878-040 is the United States. That matters if you are buying against a procurement rule on domestic content for a government, healthcare, or education project. The orderable part number is 878-040.
