Dual-wall pipe with integral bell

Product Type: Dual-Wall


GOLDFLO WT® is high density polyethylene plastic pipe with a watertight integral gasket bell and spigot coupling system. This superior design results in a watertight pipe with maximum strength and optimum flow characteristics.

GOLDFLO WT® is manufactured to the stringent requirements of AASHTO M294 or ASTM F2306, along with the ASTM D3212 watertight laboratory test requirements, making it ideal for projects where cost, installation efficiency, product quality, and watertight performance are critical.
