YATAI Fuel Dispenser Hose / DEF Urea Hose & Assembly

Mar. 25, 2020

I believe everyone is no stranger to the Fuel Dispenser Hose, but do you really know about the Fuel Dispenser Hose? Professional people do professional things, so let's introduce them in detail below: 


1. Hose application

It is generally used in refueling equipment to transport aviation kerosene, gasoline, diesel and other fuels, and the operating environment of aromatics content is not higher than 60%; it is also suitable to transport leaded or unleaded gasoline, biodiesel, etc.   


2. Executive standard: EN 1360 (international standard) HG / T3037 (Chinese standard)


3.Hose structure

The inner lining is composed of a smooth fuel-resistant rubber or thermoplastic elastomer (TPE).

The reinforcement layer consists of suitable reinforcement materials

Outer cover is made of non-corrugated, fuel resistant, weather resistant rubber or TPE

Common dispenser hoses are mostly made of SBR (oil-filled styrene butadiene rubber), NBR (acrylonitrile butadiene copolymer / nitrile) or their composite materials

Appearance color: glossy black, red, blue, yellow, green, gray and other colors.


4.Hose Model

According to the material structure of the reinforcement layer between the inner and outer rubber, the common types of dispenser hoses are:

Type 2: Reinforced with fabric and copper wire; reinforced with braid and copper wire between inner and outer rubber,

Provides torsional flexure, suitable for coiling, winding around a cylinder, or curved suspension.


Type 3: Reinforced with fine metal wires; reinforced with double steel wires between the inner and outer rubber to provide low expansion performance.

It is suitable for winding or bending hanging around the cylinder.


5Hose category: According to different conductive types, it is divided into M categories: wire conductive; Ω category: rubber conductive

6. Working pressure: The common pressure range is about 16Bar, the burst pressure can usually reach 48bar, and the highest can reach 75bar.

7. temperature range

Normal temperature level: ambient working temperature is -44 ℃ to + 120 ℃;

Low temperature level: The ambient operating temperature is -55 ° C to + 100 ° C.

8. Of course, we can provide the joints of the tanker pipe, we can also make an assembly for you

Connector standards are: NPT and BSP 


9. Nozzle

Appearance color: red, yellow, green, black and other colorsr     

Second, after reading the detailed introduction above, I believe that everyone has a certain understanding of the Fuel Dispenser Hose. 


In addition to the Fuel Dispenser Hose, there is another product that we want to introduce to you. It is an environmentally friendly product, and this product is also on the market Product with huge demand--DEF Urea Hose  



Used to transport DEF urea solution for diesel vehicles. Resistant to DEF urea solution corrosion, helping diesel vehicles meet emission regulations and purify the environment. The urea solution for vehicles is called AdBlue in Europe and DEF in North America. It is a liquid reducing agent installed in the exhaust system of diesel engines to catalyze the reduction of nitrogen oxides in the exhaust gas into nitrogen and water. SCR system. The urea solution for vehicles is a special reducing agent for diesel engines. It is stored in a special storage container on the diesel engine. After the exhaust gas is discharged from the engine, it will reach the truck catalytic converter with the exhaust gas, and then convert nitrogen oxides into harmless nitrogen and water. Make vehicle emissions meet Euro IV or higher standards.

2.Environmental standards

It has been strictly tested by the authoritative structure of SGS and complies with EU environmental protection standards ROHS, PAHS, SAE-China J2902-2013 standards.

Technical standard: SAE-China J2902-201

3.Hose structure

Inner rubber layer: EPDM rubber with special formula that is environmentally friendly and resistant to DEF solution. Does not contain Ca, Cu, Zn, Cr, Ni, Al, Mg, Na, K ionic components, ensuring that the hose is filled with urea solution and highly environmentally friendly and clean, has no effect on urea solution, no pollution and no damage to SCR .

Reinforcement layer: High-strength synthetic fiber or steel wire braided layer. There is no expansion of the hose when filling is under pressure to ensure accurate filling measurement.

Hose protective layer: EPDM super wear-resistant, anti-static, anti-aging synthetic rubber. More durable than ordinary rubber hoses for 3 ~ 5 times.

4. Applicable temperature: -40 to 90 ° C.

5. Appearance color: black or gray

6. Antistatic design: The rubber layer is conductive, and the resistivity R <106ohmm, which meets the American ASTM antistatic design standards. 

Note: General rubber hoses contain a large amount of Ca ions and other components, which will pollute the urea solution, poison the catalyst of the SCR system, and affect the conversion efficiency of SCR reduction! Inferior urea hoses are not abrasion-resistant and aging-resistant, and are easy to wear and age! Poor quality urea hoses have no anti-static design, which is prone to electrostatic hazards when filling!

Yatai has carried out professional third-party testing on urea tubes for vehicles, all of which meet the requirements of international standards


Yatai Especial Rubber Products Co., Ltd. has been committed to providing customers with high-quality products and services, and has an excellent R & D and production team to provide safe and reliable hose solutions for fluid transportation.
