High-Strength Flexible Bellow Pipe for Fuel Dispenser Connection


Global Multi-Functional Fuel Dispenser Bellow Pipe and Metal Hose Solution


In modern gas station design, an efficient and safe fuel delivery system is essential. The BWG series of bellow pipes and the BWG-SCM series of stainless steel metal hoses are designed specifically for pipeline connections under fuel dispensers. Whether for fuel pumps, tanker trucks, or storage systems, they provide stable and reliable fuel flow solutions.


These pipes and hoses are known by different names around the world. In the United States, engineers often call them “Fuel Dispenser Flex Hose” or “Flexible Bellow Pipe”; in Europe, the German and French markets refer to them as “Tankstellen Wellrohr” or “Tuyau Flexible de Distribution de Carburant”; in Asia, such as Japan and Korea, the industry uses “ガソリンディスペンサーホース” (gasoline dispenser hose) and “연료 디스펜서 플렉시블 호스” (fuel dispenser flexible hose). This variety of naming reflects the global applicability and wide recognition of these products.


Product Highlights:

Multiple Material Options and High-Pressure Design
The BWG series is made of stainless steel 304, offering excellent corrosion resistance and compatibility with gasoline, diesel, kerosene, and AdBlue. Flanges can be made of carbon steel or stainless steel according to requirements, with a working pressure up to 0.25 MPa. The BWG-SCM metal hoses feature an additional stainless steel braided layer for enhanced pressure resistance up to 1.0 MPa (10 bar), while maintaining flexibility to withstand frequent operation and vibrations.


Various Connection Configurations
Multiple interface options are available, including triangle flanges, welded flanges, male threads, and female threads, compatible with international standards (BSPT, NPT, etc.). Hose lengths can be customized from 300 mm to 600 mm to ensure flexible installation and tight connections.


Temperature Resistance and Durability
All pipeline components can operate in environments ranging from -30℃ to +55℃. The metal maintains excellent elasticity, resists deformation, ensures leak-free performance, and provides long service life.


Easy Installation
The flexible design enables quick and convenient installation, supporting both swivel and fixed mounting. This facilitates maintenance and replacement, improving operational efficiency at gas stations.


Applications
BWG and BWG-SCM series below pipes and metal hoses are widely used for fuel dispenser bottom connections, tank pump interfaces, fuel distribution systems, and industrial storage pipelines. They are compatible with fuel equipment and fluid media standards worldwide. Whether for commercial gas stations or industrial storage systems, these high-performance pipes offer safe, stable, and precise fuel delivery.


Global Customer Recognition
From North America to Europe, from Japan to the Middle East, engineers and gas station operators highly praise the BWG and BWG-SCM pipes for their high-pressure resistance, corrosion resistance, and ease of installation. Whether you call them “Flexible Fuel Hose”, “Wellrohr”, or “플렉시블 호스”, this solution meets all your fuel transfer needs.
