Sioux Chief 87911 Slotted Polypropylene Test Plug, 8790 Series, Less Insert

Sioux Chief 87911 Slotted Polypropylene Test Plug, 8790 Series, Less Insert

The Sioux Chief 87911 is a slotted test plug from the 8790 Series, molded from reinforced polypropylene and supplied less insert (no threaded brass insert included). The 8790 Series slotted test plug platform is available in sizes from 1-1/2" through 4" to match ABS or PVC drain, waste, and vent pipe and fittings during rough-in pressure and leak testing. Across the size range, every plug in the series shares the same reinforced polypropylene construction, slotted removal design, and less-insert configuration, seating into pipe without binding or seizing over repeated test cycles. This is a trade rough-in component intended for plumbers and contractors sealing pipe runs prior to wall and floor closure, not a finish or decorative fitting.

Why Sioux Chief?

Sioux Chief builds every size in the 8790 Series test plug line from reinforced polypropylene specifically so it won't seize onto ABS or PVC pipe the way traditional plug materials can after repeated test cycles. That chemical-resistant, durable construction, consistent across the 1-1/2" through 4" range, gives plumbers and contractors a plug they can rely on to seat, hold, and release cleanly during rough-in pressure testing, backed by Sioux Chief's long history supplying rough-in plumbing hardware to the trade.
