UNISEALs are great for aquaponcis because they create a water tight seal. This makes it easy to fit a pipe into a hole in a tank. UNISEALS provide more versatility than a traditional bulkhead, handling irregularities and curvatures with ease.
The UNISEAL offers longevity, easy installation and a reduction in labor and material costs. It is made to withstand pressure and suction as well as acids, oils, greases, gasoline, sewage, waste, heat and cold.
