DG-01 Tight Seal Fill Cap

Tight-Fill Top-Seal Caps are installed on top seal adaptor, when not in use, to prevent gasoline vapors from escaping and to prevent water, dust, and debris from entering tank. The DG-01 is designed to mate with 4" LJQ-01 Top Seal Adaptors. Heavy duty and corrosion resistant, the body is made of PA66 to help eliminate rust and oxidation for a long maintenance-free life. The toggle lever distributes downward pressure to compress its Buna-N gasket evenly, assuring a positive, water and vapor-tight seal. The DG-01 can be locked with a padlock or wire seal.
