Fill Point & Vent Fittings

The Cleanfill 2" Overfill Prevention Valve from Lafon can be fitted to a tank as a piece of safety and environmental protection equipment. This overfill protection device can be used on fuel and diesel storage tanks that are filled by gravity flow or a pressure pump system. When the tank is full, the valve will close preventing any further fluid from being dispensed into the tank. There is also a version available to be used on AdBlue™ storage tanks, a fluid which is known as DEF in America and other countries.

The Fuel Tank Vent Cap is to be used on an above ground fuel storage tank’s 2” male thread to provide ventilation. These vent caps, which are designed to be fitted on to heating oil storage tanks, have a plastic mesh that prevents particles and debris from getting into the tank from this point. As these have no thread, either side of the oil tank vent cap has a screw that cuts into the male thread on the tank enabling it to be held into place.

The SpillStop 2” Overfill Prevention Valve protects both the environment and the individual from the effects of fuel spillage. This overfill protection device is suitable for use on both fuel and diesel storage tanks, which may have a pumping or gravity feed system. Once the tank has reached its maximum fuel capacity, this valve will close to prevent any additional fuel from being delivered, thus preventing overfilling. A version of this can be supplied specifically for use on plastic tanks.

The Plastic Fuel Tank Filler Cap is a cost effective solution to cap off male threads on fill points on fuel storage tanks, tanker faucets and valves. The main function of a tank fill point cap is to prevent dripping and to stop unwanted debris and water from entering into the fill pipe. Whilst they are primarily sold as a diesel or oil tank cap, they are a multipurpose solution that can be used with any compatible fluid.

The plastic fuel tank filler cap is a basic option when no additional security is required, and benefits from small lugs positioned around the cap and an alloy chain and clip to make it easier to fit and remove by hand.
