The Fill Cap is installed at the top end of the discharge pipe of the Underground Fuel Storage Tank. Its function is to prevent the entry of elements that may contaminate the fuel stored inside the Tank, as well as allow the proper coupling of the Tank Truck, thus allowing the safe unloading of the product.

Zeppini Ecoflex Fill Cap consists of a collar and cover set, and it is available in either brass or aluminum. In addition, it features an opening for the insertion of a padlock, to avoid free access to this area of the installation.
