Manhole adapter and plate (transparent) 100mm stainless steel, can be retrofitted!

Manhole adapter with Macrolon (transparent) cover plate for inspection.

Openings / manholes to be able to check and clean the fuel tank are often missing, making the contamination uncontrollable and increasing the risk of, for example, a sudden engine shutdown.

Once the tank (for fuel, waste water, etc.) has been installed in the ship, it is often difficult and sometimes even impossible to get good access to the tank afterwards, without having a neck breaking and / or having to be faced again and again with leaks.

After mounting our stainless steel manhole adapter you can check the tank and easily clean the inside. The manhole adapter is easy to assemble and can be mounted on the top or side of the tank.
The manhole adapter consists of a cleverly constructed hinged flange with TIG-welded threaded ends, complete with oil-resistant gaskets and is available with a stainless steel cover plate.

The manhole adapter is made of 3 mm thick stainless steel and is supplied with stainless steel washers and nuts. An external gasket and a cover plate complete the manhole adapter. The manhole adapters are supplied with a handy drilling template. For the Ø 200 mm version we recommend using the cover plate as a drilling template, or copying the contours of that cover plate onto a sufficiently large piece of paper and then using that as a drilling template. The Ø 150 and 200 mm versions are ISO 21487 certified.
The manhole adapter can be mounted in tanks made of plastic, steel, aluminum and polyester.
