Sioux Chief 882-98 Rubber Expansion Test Plug 8 in Sch 40

Product Description

The SIOUX CHIEF 882-98 is an 8-inch rubber expansion test plug designed for pressure-testing and isolating drain, waste, and vent piping systems. The plug expands mechanically to create a watertight seal inside the pipe, allowing technicians to pressurize the line and verify integrity before final inspection. It fits Schedule 40 pipe and Sewer DR-18 pipe at the 8-inch nominal diameter. Plumbers and pipefitters rely on this type of plug during rough-in inspections and final plumbing code sign-offs on both residential and light commercial projects.

This plug is suited for use in 8-inch diameter drain and sewer piping during hydrostatic or air pressure testing as required by local plumbing codes. Compatible pipe schedules include Schedule 40 and Sewer DR-18. It is commonly used at cleanout openings, pipe ends, or test tees during rough-in and pre-inspection stages of a project.

Key Features

• Fits 8-inch nominal Schedule 40 and Sewer DR-18 pipe
• Rubber expansion design creates a positive mechanical seal inside the pipe bore
• Supports hydrostatic and low-pressure air testing applications
• Reusable construction for multiple test cycles
• Sized for large-diameter drain and sewer lines typical in commercial rough-in work

Compatibility

Designed for use with 8-inch nominal Schedule 40 and Sewer DR-18 pipe, as specified by the manufacturer.

Installation Notes

Installation is typically performed by a licensed plumber during the pressure-testing phase of a project. Shut off all connected water supply and isolate the test section before inserting the plug. Follow IPC and applicable local code requirements for minimum test pressure and duration. Do not exceed the rated pressure capacity of the plug or the pipe system under test.
