In case of a fire the built-in thermal protection on the QCC connector melts allowing the nipple to disengage from the tank connection and stop the flow of propane. They also provide a positive back check seal at disconnect to eliminate the propane in the hose from being released into the atmosphere.\u003c\/p\u003e","brand":"Marshall Excelsior","offers":[{"title":"Default Title","offer_id":52790744973612,"sku":"MEXME518","price":16.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/5317\/4572\/files\/277-ME518.jpg?v=1774476718","url":"https:\/\/www.freeportmarine.com\/products\/marshall-excelsior-me518-jec-type-i-qcc-connector","provider":"Freeport Marine Supply","version":"1.0","type":"link"}
