Nova’s standard commercial hydrant fueling pit consists of a unique milk bottle shaped molded fiberglass shell, and a cast aluminum lid assembly rated to support aircraft wheel loads. The innovative fiberglass shell design provides a large 36″ diameter shell body enabling maintenance personnel to easily access the hydrant valve. The sloped pit floor provides a natural sump for the efficient removal of both spilled fuel and water. The pit design allows for a standard bottom pipe penetration or a side wall pipe penetration complete with a single or double Buna-N-Rubber boot. The cast aluminum lid assembly consists of an outer ring complete with pretaped holes for lifting eyes, and a hinged lid which opens 180 degrees. Both the lid assembly ring and lid come complete with a fuel resistant O-ring seal in a machined groove for a water resistant seal.
