As the entire cooling system heats up and cools down, the density of the coolant, in most cases water/glycol or water/ELC, will vary. In order for everything to work properly, an optimal working condition of the water pump is important.
In order to guarantee a long pump life and to minimize cavitation (imploding of air bubbles), it is essential that the pump has the correct pre-pressure (head) to pump the desired flow rate through the entire cooling system. All this, including venting the radiator and the engine, is achieved by the pressure cap.
Oversluizen manufactures a large part of its pressure caps in stainless steel 316, suitable for the maritime industry.

Filler neck on mounitng plate
In addition to the loose pressure caps, filler necks on mounting plates are also available, with a standard hole pattern and optionally including an overflow pipe available from stock.
