2 Stainless Steel Bulkhead Fitting – Perfect for the self-sufficient homesteader, rancher, or farmer, this tank bulkhead fitting is crafted of high quality 316 Stainless Steel, and is ideal for use on anything from your 55-gallon blue barrel to your 20,000 gallon storage tank! Being made of Stainless Steel makes it ideally suited for a wide variety of applications, including agriculture, reverse osmosis systems, indoor farming, rainwater harvesting, well water storage and purification systems, and many more! Here are a few of the features you will love. 100% 316 Stainless Steel Construction – store potable water, DEF, liquid feed, fertilizer, and much more! Double-Threaded with Industry Standard NPT Threads – easily attach plumbing inside the tank, like a siphon tube, and outside the tank, like a ball valve. Easy to Install – just drill a 3″ hole, feed the barrel through from the inside, and tighten the nut (4″ wrench required to tighten the nut). EPDM Gasket – safe for use in your drinking water storage tank. Heat Resistant – both the gasket and fitting itself perform well at high temperatures. Versatile – install it on drums, barrels, and tanks with a wall thickness up to 1 7/8. However, what really sets this tank adapter apart from the rest is its “wrenchability”. If you are a seasoned installer out of the field, then you know that nothing is more frustrating than attempting to tighten the nut of a tank bulkhead while the body keeps moving on you. Enter the Pipe Fitting Store bulkhead, manufactured with grooves designed specifically for a 2 1/2 wrench to grab the barrel of the fitting while you tighten the nut and complete your tank tap. It is what makes this bulkhead an installers dream! Common Compatible Liquids (not an exhaustive list). Potable and Non-Potable Water. Diesel Exhaust Fluid (DEF). Most Detergents and Soaps.
