Frequently Asked Questions for

One Way Serrated Spring Insert Clamp

The One Way Serrated Spring Insert Clamp (SFS) is a medium-duty worm drive clamp designed to handle thermal fluctuations in applications. It features a spring insert mechanism that automatically re-tensions the clamp to maintain a secure seal as hose diameters expand or contract due to temperature changes.

  • Designed according to German DIN 3017-01 standards for medium-duty applications.
  • Worm gear mechanism for easy tightening or loosening.
  • Spring and bridge construction for automatic re-tensioning to prevent seepage.
  • Smooth inner surface to prevent hose damage, making it suitable for soft nitrile hoses.
  • Available in a wide range of diameters and customizable as per customer requirements.

The One Way Serrated Spring Insert Clamp is made with high-quality materials, including:

  • SS430 grade or plated carbon steel with Hexavalent or Trivalent Zinc plating.
  • The spring and bridge components are typically made from SS301 material for added durability and flexibility.

The clamp is widely used in industries where temperature fluctuations and secure connections are critical, such as:

  • Automotive applications
  • Engine systems
  • Earthmoving equipment
  • Agricultural machinery
  • Genset (generator set) systems

The spring insert mechanism accommodates changes in joint diameter caused by thermal expansion or contraction. It ensures consistent clamp load, prevents loosening, and reduces the risk of leaks or seepage.

The smooth inner surface eliminates the risk of hose biting or damage, making the clamp ideal for soft materials like nitrile hoses, which are commonly used in automotive and industrial applications.

Yes, the clamp is available in a variety of diameters and can be customized to meet specific customer requirements, ensuring flexibility for diverse applications and industries.
