4" Bulkhead Fitting / Tank Adapter
These heavy duty polypropylene Bulkhead Fittings provide the strongest, most watertight seal through a plastic tubs, glass aquariums, metal containers and flexible pond liners. They allow full flow of water and the ability to attach flexible pipe with the use of a threaded male adapter. The extra thick EPDM rubber gasket maintains a water tight seal to prevent leaks. These fittings have left handed threads to prevent the bulkhead from loosening when installing the male adapter. Best used on straight walled containers or semi-flexible containers with only slight curves.
