Listed at 10.94 USD. 8mm BULKHEAD / Through-Hull Tank Connector - 2 Pack PRODUCT DESCRIPTION Description To attach 8 mm Blumat water supply line to a rain barrel or water storage tank. This is your classic bulkhead fitting, made in Austria, high quality and efficient for a Blumat System. Bulkhead fittings allow you to penetrate through a wall or barrier, while allowing passage within the fitting. This allow you to tap into a tank of water, while allowing water to pass-through the bulkhead fitting, and into a water supply line. We have these pre-drilled into our 5-gal bucket reservoir, see related products below. Have your own reservoir? No problem, simply drill 1/2" holes into your own water tank and convert it into a Blumat Reservoir. We have even higher quality bullhead fittings, some that stop water flow when disconnected. Check out our bulkhead fittings category. *Reservoir not included, look into Blumat Reservoir or 5-gallon bucket if you need a reservoir ? Copyright . All rights reserved.
