Flexitank dual layer waste holding marine bladders

Marine Flexitanks

Why carry bulky jerry cans or expensive rigid tanks when every spare inch of onboard space is valuable? With Flexitanks, your unused space holds liquids such as potable drinking water, diesel, as well as black and grey water.

Some manufacturers use old high-frequency technology to weld bladder outer edges.  Some have even tried to copy what we do.  But there is a reason we have been manufacturing for 28 years and exporting our products all over the world.  Its quality and ingenuity in manufacturing. FTA only use the latest hot air technology to create seamless sided bladders. Fewer welds mean fewer weak spots, so your new Flexitanks will last longer and take you further.
