Sioux Chief 878-30PK 3" Polypropylene Pipe Plug with Brass Insert

Sioux Chief 878-30PK 3" Polypropylene Pipe Plug with Brass Insert

The Sioux Chief 878-30PK is a 3" polypropylene pipe plug built for rough-in drain, waste, and vent (DWV) plumbing installations. Molded in white PP for corrosion resistance and long-term durability, the plug incorporates a brass insert that gives installers a solid, reusable connection point for later removal or service access rather than a plug that has to be cut or broken out of the pipe. Manufactured in the United States and supplied in a 25 EA case pack, this plug gives plumbing contractors and rough-in crews a dependable, jobsite-ready closure for 3" DWV pipe runs, keeping the line sealed until final trim-out or service work is needed.

Key Features

• Trade Size: Sized to fit 3" DWV pipe for a secure, properly seated plug.
• Polypropylene Construction: Durable white PP body resists corrosion and holds up to jobsite handling during rough-in.
• Brass Insert: Integrated brass insert provides a threaded, serviceable connection point so the plug can be removed or accessed after installation without damaging the surrounding pipe or fitting.
• Removable by Design: The brass insert lets a crew pull the plug for inspection, testing, or future tie-in work instead of cutting the pipe to get past a permanent cap.
• White Finish: Consistent white PP finish for a clean, uniform appearance behind the wall or below the floor.
• Case Packaging: Sold in a 25 EA case pack, making it practical for distributors and contractors to stock for multi-unit rough-in jobs.

Why Sioux Chief?

Sioux Chief builds its 878-30PK pipe plug from durable white polypropylene and backs it with a brass insert, giving plumbing contractors a plug that seats securely on 3" DWV pipe and can still be serviced later without replacing the fitting. As a product manufactured in the United States and shipped in convenient 25 EA case packs, it is sized for professionals who need a dependable, job-ready pipe closure for rough-in work rather than a one-off retail fix. For plumbing contractors and distributors stocking rough-in DWV specialty parts, the 878-30PK offers a consistent, repeatable solution that keeps 3" pipe runs closed and protected until the job calls for that line to be opened back up.
