Liquidtight tubing is designed to house and permanently protect underground cable from moisture, grit, rodents and other environmental hazards that can damage the cable over time. The Kellems brands of liquidtight PolyTuff I conduit and PolyTuff II tubing feature non-metallic, PVC-based construction, avoiding the challenges of corrosion while providing high strength, superior flexibility and outstanding handleability. When compared to metals, they can be deployed in flexible directions, even accommodating tight turns. They can be cut cleanly with no damaging jagged edges, and help avoid costly fatigue and section separation issues. Sizes are available from " to 2" in diameter. Kellems liquidtight conduit pairs with nylon connectors that are completely non-conductive, corrosion resistant and easier to install than metallic liquidtight fittings. They feature a patented SwivelLok design that eliminates the need for separate straight, 45-degree and 90-degree fittings by providing a full range in one device. In addition, these Kellems non-metallic connectors have a unique design which allows UL 50 ratings of 3R, 4X, 12 and 13.
