VERY IMPORTANT: READ EVERYTHING ON THIS PAGE BEFORE CLICKING. We carry more bulkhead (aka tank adapter) fittings than anyone on the net. It can become confusing, so take your time to review every page we have listed below. Bulkhead fittings are identified by the size of the pipe it connects to, not the hole size. (There is an exception to this. Our new Quick Disconnect (QD) 150PSI Modular Bulkhead System) When we describe the bulkhead fitting, the first designation is the flange side and the second is the back side. ie, fpt (female npt)x slip means the flange side has a female pipe thread and the back side would have a slip socket for pipe to be glue into. Again, size always represents the pipe size that fits the bulkhead fitting (aka tank adapter), not the hole size. With that said, if you click on one of the links below, it should give you the hole size for each bulkhead fitting (aka tank adapter) in the description for the item. If you don't find the size bulkhead fitting you want in one category, look in some of the others. All bulkhead fittings come with at least one gasket and one nut unless stated otherwise in the description. Extra nuts and gaskets are available at the link near the bottom of this list.
Economy Bulkhead fittings 1/2" to 2" - These are all ABS and available in 4 different configurations: Slip x slip, slip x fpt, fpt (female npt)x slip and fpt (female npt) x fpt. Sizes available are 1/2", 3/4", 1" 1.5" and 2". All are black in color.
