Loose-Fill Pipe Cap Assemblies are installed in spill containment manholes on fill riser pipes from an underground fuel storage tank. They are used when a tight-fill connection is not required.
The OPW 83 Fill Cap Assembly threads onto the fillpipe of an underground or aboveground tank. The screw-on cap is gasketed to assure a tight seal against air, water, dust and debris. The 83 can be locked with a padlock or wire seal.
