Weather, road debris and other environmental conditions are all factors that can contaminate your LNG Fueling Receptacle.  Blowing off your receptacle before fueling won't blow away the dried contamination any more than washing your car with an air hose.  The solution is to keep the Receptacle clean.  The Macro Technologies Fueling Cap is the only cap on the market that will do that.

The Macro Technologies Fueling Cap features an interior O-ring seal and filtered breather.  The O-ring seals the receptacle’s vent holes while a garter spring along the ID of the Fueling Cap holds the cap securely onto the receptacle.  These unique features provide a seal rather than just a cover, unlike the other dust caps on the market.

A simple water test can be used to illustrate the difference between Macro Technologies’ Fueling Cap and the other dust caps on the market.

When a dust cap is placed on a receptacle, it does not effectively seal the vent holes on the receptacle.  Submerging a dust cap covered receptacle in water demonstrates how susceptible the receptacle is to contamination.  Within seconds, water will enter the receptacle.

Whereas the dust caps allowed water to enter the receptacle within seconds, the Macro Technologies Fueling Cap limits the intrusion of contaminants.

Even after several minutes of being submerged, the Macro Technologies Fueling Cap allows only a small amount of filtered water in through the "Filter/Breather".  Because the Macro Cap is fully sealed, the Macro Filter/Breather is needed to allow any residual liquid LNG left from the filling process to escape as it warms up and turns to a gas.

For cleaner LNG fueling systems, use the Macro Technologies Fueling Cap.
