ABSTRACT:
Secondary containment of the flexible hose connection between the underground hydrocarbon fuel fiberglass supply pipe and the emergency shut-off valve feeding a gasolene dispensing pump is obtained with a univerally applicable elastomeric corrugated sleeve that is secured at opposite ends, respectively, to the supply pipe and an adapter at the valve by non-metallic clamps. The clamps are of split ring construction with an initial small gap at the end of a projecting lip which is compressed upon tightening a glass reinforced Nylon bolt. This ensures smooth uniform contact with the sleeve for a full 360.degree. circumferentially. Adapters provide the "nipple" surface to which the sleeve is clamped. An air valve is provided in the sleeve to permit pressure testing and to enable leak detection, if desired.
