Nauta Flexible Tanks provide many advantages over rigid tanks andhave, therefore, become very popular with both yacht-builders andboat-owners. Each of these tanks uses an extremely rugged 840-Denier nylon fabric, coated on both sides with a neoprene/nitrile compound. Heavily lapped seams are inside-reinforced with a "doubler" to provide extra strength. Nauta tanks are very easy to work with. Several models are available with fittings already installed. However, Nauta's construction also allows custom placement of fittings to suit your particular requirements andmakes it simple to install them. Nauta tanks are vulcanized to assure leak-proof panels andseams for years of trouble-free service Because of their flexibility andthe Nauta range of sizes, these tanks can fit into almost any space, especially those odd-shaped places that would otherwise be wasted A flexible tank is unique in operation: as liquid is drawn out, the tank "collapses" This not only eliminates the need for venting of water tanks but also minimizes free-surfacing action which dramatically reduces sloshing andits noise Natua flexible water tanks use an exclusive Tedlar inside lining to maintain a taste-free system No venting is required for water tanks Includes (1) FTP010 Spanner Wrench
