Flexible Water Tanks and Holding Tanks

Flexible marine water and boat holding tanks from Defender Marine offer boat owners the opportunity to fit their preferred tank into any configuration under the deck.

What are the different types of tanks?

Fresh water tanks, wastewater tanks and diesel fuel flexible tanks are all available in several sizes and shapes. From 14 gallon up to over 50 gallon with inlets and outlets in the most suitable location for most applications ? Defender also offers tanks with custom located fittings.

Defender Marine tanks are built tough.

Flexible tanks are made with an inner and an outer bladder. Plastimo tank seams are fused for strength and floating inner bladders in flexible water tanks reduce tension to prevent leakage. Nylon exteriors coupled with odorless PVC inner bladders reduce tastes in water tanks. Vetus tanks boast a three-layer design and Nauta combines neoprene and nitral compound bladders with trademarked Tedlar inner bladders for tasteless boat water tanks and extra strong diesel tanks.
