Chemque's Q-Seal 290S is a polyurethane product primarily used to seal traffic detector wire loops like the Marsh Products Preformed Saw-Cut Loops in channels cut into asphalt or concrete. It requires no mixing, can be applied in winter or summer, and protects the wire loop from contact with water, oil or other chemicals.

The 30-ounce tube fits in a manual or air-operated caulk gun.

Each tube comes with a flat nozzle designed to fit into the loop channel for easy installation.
