SEMPERIT FUB fuel hose

What is the Semperit FUB hose ? Semperit FUB is a high-quality rubber hose compliant with the SAE J30R2 standard, designed for the transport of gasoline, diesel fuel, mineral oils and mixtures containing ethanol. Thanks to its reinforced construction and excellent chemical and temperature resistance, it is widely used in the automotive industry and general industrial applications. 

Construction and properties of the FUB hose

• The Semperit FUB hose has been developed to maintain maximum durability even in demanding operating conditions: 
• Inner layer: NBR (nitrile) rubber – resistant to fuels and mineral oils, ensures tightness and does not react with the medium.
• Reinforcement: synthetic fiber braid – increases resistance to working pressure and stretching.
• Outer layer: CR (chloroprene) rubber – resistant to ozone, oil, fuel and atmospheric factors.

The Semperit FUB hose is characterized by exceptional durability and resistance to intensive use, thanks to which it is perfect for demanding working conditions. Its construction ensures a long service life, even with continuous contact with fuels and oils. It stands out for its very good flexibility, which facilitates assembly and use in places with limited space, as well as high resistance to bending, which prevents cracks and deformations of the hose. Additionally, the outer layer made of rubber resistant to abrasion and the influence of atmospheric factors ensures that the hose maintains its properties for a long time. The Semperit FUB hose meets the rigorous requirements of SAE J30R2 and DIN 73379 Type B standards, which confirms its quality and compliance with international safety standards.

Application of the Semperit FUB hose

• This type of hose is used in:
• fuel systems of internal combustion vehicles,
• diesel fuel transmission lines,
• power supply systems for industrial engines and generators,
• agricultural and construction machinery and power generators.

The FUB hose is perfect for working with fuels containing up to 50% benzol and in mixtures with ethanol (E10, E20).

SAE J30R2

SAE J30R2 is an international standard defining technical requirements for flexible rubber hoses for fuels and oils. It is primarily used in the automotive industry, general industry and agricultural machinery, where high resistance to fuels, mineral oils and external factors is required. Hoses compliant with the SAE J30R2 standard are designed for operation in low and medium pressure systems, where media such as gasoline, diesel fuel, ethanol mixtures, lubricating oils and other petroleum products are transported.
