Poly Pipe Plug, 3"

Poly Pipe Plug, 3"

The 8F300 Poly Pipe Plug is a 3" Schedule 80 threaded polypropylene plug built to cap off compatible threaded poly fittings with a strong, durable seal. Made from glass-reinforced polypropylene, it’s designed for tough service and pressure-rated performance—because when you close a line, you want it closed, not “mostly closed.”
