  • Marine Fuel Bladders: the marine fuel bladders are constructed from top grade TPU coating fabric for oil and chemicals. All seams are weld by HF welding technology, without using any glue or hot-air. It ensure the higher strength.

  • Filling Fittings: we use the aluminum, stainless steel or PP flange and 1-1/2’’ cam-lock with one safety cap. When filling fuel, the user can take offer the safety cap, connect the male com-lock end with the female com-lock end of filling hose. Or, put the filling hose into the com-lock directly.

  • Outlet Fittings: we use the aluminum, stainless steel or PP outlet port flange. Then, connect with one 90 degree elbow and one 1’’ stainless steel ball valves, end with one PP hose nozzle.

  • Fuel Hose: we will provide one 2m length fuel hose with nozzle for each bladder. The longer hoses are available upon request.

  • Ground Sheets: the standard ground sheet is white color. it is optional parts. I will be supplied upon request.

  • Tie-Down System: there are fours mooring points on the marine fuel bladders. The users can use the rope or belts connect it with the boat to fix.

  • Optional Accessories: we also supply the hand bags, sun-shield and other accessories upon your request.

Marine Fuel Bladder Specification

There are two typical types of marine fuel bladders: Pillow Type and Cube Types. Its standard sizing range from 100L to 3,000L.

We also can make other shapes and customized sizes upon specific request. Below you will find typical sizing and filled dimensions for our marine fuel bladders. Collapsible marine fuel bladder tanks fold flat for easy storage and transport and are easy to fill and drain.

We abandon the traditional hot-air welding technology. The hot-air welding seams are not persistent. The seam is easy to seperate. Some inferior bladders prefer this welding.

Marine Fuel Bladders Material

Our collapsible marine fuel bladders are made of high-quality TPU coating fabric material allow for oil or fuel long-term storage due to their excellent material properties. For long-term storage applications, built to withstand extreme conditions and provide the highest level of reliability.

You also can advise us the time of use, desired chemical resistance and expected mechanical stress. We will make the products meet your requirements.

DOOWIN marine fuel bladders meet the highest quality demands.

  • Excellent abrasion properties
  • Supreme oil-resistance
  • Top notch UV resistance
  • Superb fire-resistance
  • Cold resistance to -70 ℃
