Fuel liquid level sensors come in many different shapes and sizes for a variety of fuel level applications. Rogers NITROPHYL® NBR floats are the leading material used for level sensing floats in automobiles, motorcycles and off-road vehicles. NITROPHYL’s unique characteristics make it the ideal material for fuel level sensing and accurate gas gauge readings.

Unlike hollow-core plastic or metal floats which can fail suddenly, NITROPHYL® NBR floats are made of closed cell foam, giving the float a solid core that improves reliability and lifetime of the float. The proprietary NBR compound provides excellent resistance to all fuels.

Engineered to provide enhanced resistance to flex fuels, NITROPHYL®-M floats were developed specifically to improve resistance to methanol and other alcohols and are widely used in fuel tank applications.
