Tank Fittings & Hardware
Valves, flanges and replacement parts for poly tanks
Plumb, fill, drain and maintain a plastic tank with the parts here: 2" and 3" full port and stubby valves, bolted and bottom drain flanges, poly tank flange assemblies from 3/4" to 4", sight glass kits, a tank level gauge, baffle balls, internal baffle systems for transport tanks, rain harvesting and overflow kits, and a first flush diverter. For Peabody tanks we also carry Gemini double wall fittings, seismic kits, WeatherGuard seal kits, fiberglass wraps and replacement plugs and lids.
Match each part to your tank: pipe size and connection type for valves and flanges, lid size for baffle balls and rain kits, and tank model for Peabody parts. See our storage tank fittings guide.
