Sioux Chief 878-030 3" Polypropylene Slotted Plug, White, Less Insert

Sioux Chief 878-030 3" Polypropylene Slotted Plug, White, Less Insert

The Sioux Chief 878-030 is a 3" polypropylene slotted plug built to cap open pipe fittings during rough-in plumbing work. Molded in white PP for resistance to corrosion and everyday jobsite chemical exposure, it features a slotted head that lets installers seat and remove it quickly with a standard flat-blade screwdriver instead of specialty tooling. This plug ships less insert, meaning the insert/gasket component is not included and should be selected and ordered separately to match the specific fitting and application. Manufactured in the United States and packaged 25 pieces per case for distributor and contractor stock, the 878-030 is sized for straightforward professional use wherever a reliable 3" fitting plug is needed on a rough-in job.
