Flexible Metal Hoses
QualityFlex offers premium flexible metal hoses for diverse applications, ensuring reliable and efficient solutions with superior performance and durability.
Leading Metallic Flexible Hoses Manufacturer
We are recognized as one of the top metal hose manufacturers, suppliers, and exporters of flexible metal hoses in various sizes, types, and grades. Our metal hose products are engineered for peak performance in demanding industrial environments. Each flexible metal hose features a stainless steel convoluted core for enhanced flexibility and durability, reinforced with wire braiding to resist pressure and prevent stretching. For high-pressure metal hose applications, we use multiple layers of braiding to increase pressure resistance.
Our Stainless Steel Corrugated Flexible Hoses conform to BS:6501 part-1 2004 and IS:10380 standards, ensuring premium quality. We manufacture a wide range of metallic flexible hoses in sizes ranging from 6mm (1/4″) to 250mm (10″), made from AISI 304, 321, and 316L grades of stainless steel, meeting international standards.
Flexible metal hose pipes are widely used in industrial piping systems due to their flexibility, corrosion resistance, and ability to perform under extreme temperatures from -200°C to +650°C. Built for longevity, these flex hose metal products can handle high-pressure applications, making them an ideal solution for demanding conditions.

Technical Specifications of Flexible Metal Hoses
Sizes | 6mm (1/4″) to 250 mm (10″) |
Pressure | High Pressure Resistance |
Temperature Rating | High and Low Temperature resistance (-200°C to +650°C) |
Material of Hoses | Stainless Steel AISI 304 & Stainless Steel AISI 316 |
Material of braiding | For increased pressure resistance and protection, our metal hoses feature a stainless steel AISI304 wire braid for superior durability. |
Bending radius | The bending radii in the table are from the bend center to the hose’s axis. EN 10380 defines static bending radius for a single bend (e.g., installation) and dynamic bending radius for repeated bending. |
Quality Testing | Flex Fatigue or Cycle Life Test, Burst Pressure or Yield Test, Bend Radius Test & Flame Test |
Exhaust Connectors | Thin-wall connectors: vibration-resistant, customizable |
Installation Tips for Metallic Flexible Hoses
- Install the hose as close as possible to the source of vibration, ideally directly on the pump or compressor.
- Avoid compressing, twisting, or stretching the hose during installation to prevent premature failure.
- Ensure the hose length is perpendicular to the direction of vibration.
- Support the piping to eliminate stress on the hose, allowing it to support only its own weight.
End Fittings in Flexible Metal Hoses
When choosing end fittings for flexible metal hoses, it’s important to match them with the fittings they will connect to. The fittings should be the right type, size, and material to fit properly. Make sure the fittings can handle the pressure, temperature, and chemicals of both the fluid inside and the environment outside.
Our thin-wall, flexible connectors are designed to resist vibrations and provide durability. We offer multi-layer construction in various materials, including special alloys for better resistance to corrosion and high temperatures. You can customize the flexibility or stiffness to suit your specific application needs.
Quality Management for Flexible Metal Hoses
At QualityFlex, every production stage of our flexible metal hoses is closely monitored by qualified QC engineers. Our facility features a fully-equipped in-house laboratory and testing capabilities, adhering to international standards for metallic flexible hoses. Each flexible metal hose pipe undergoes hydraulic testing at 1.5 times the working pressure before dispatch, with additional pneumatic testing as necessary.
We rigorously inspect all raw materials used in our metallic flexible hoses, including hoses, braiding, and end connections, to ensure the highest quality standards. Our quality management process includes:
- Flex Fatigue or Cycle Life Test
- Burst Pressure or Yield Test
- Bend Radius Test
- Flame Test
This thorough approach ensures that our flexible metal hoses deliver exceptional performance and reliability.
