Heavy Duty Spring Loaded T-bolt Clamp (HTS)

Jolly Heavy Duty Spring-loaded T-bolt clamps are designed to suit the applications where clamps need to compensate for expansion & contraction of hose caused by Pressure, temperature and/or hose cold flow to maintain leak-proof connection.

These clamps typically find their application on silicone hoses on charge air cooling/air to air, after cooling systems, and primary engine coolant systems of Heavy Duty Trucks & Earth Moving Equipments.

Also known as Heavy Duty T-Bolt Band Clamps; HD Spring-Loaded T-Bolt; Flex Seal HD Spring Insert Clamp.

Frequently Asked Questions for

Heavy Duty Spring Loaded T-bolt Clamp

The Heavy Duty Spring Loaded T-Bolt Clamp is designed for applications requiring compensation for pressure, temperature fluctuations, or hose cold flow. It ensures a secure and leak-proof connection in demanding environments, such as heavy-duty trucks, earth-moving equipment, and industrial systems.

These clamps are used in various industries, including:

  • Automotive systems (e.g., charge air cooling and engine coolant systems)
  • Filter systems
  • Marine applications
  • Aerospace applications
  • Oil & gas systems
  • Heavy-duty trucks and earth-moving equipment

The Heavy Duty Constant Tension spring construction adjusts for high-pressure and temperature variations in the hose line. This prevents loosening and ensures a consistent, leak-proof connection even in extreme conditions.

The clamp has rounded band edges to protect hoses from biting or cutting. Additionally, the floating bridge construction provides guided tightening, preventing puckering and ensuring uniform clamping and sealing.

The clamps are manufactured using:

  • SS300 grade stainless steel
  • SS300 grade with plated carbon steel parts All carbon steel parts are zinc-plated per industry and global export standards, ensuring durability and corrosion resistance.

The self-locking nut configuration can withstand temperatures up to 250°F (121°C), making it suitable for high-temperature applications.

The self-locking nut design prevents the clamp from loosening due to heavy vibrations, ensuring long-term reliability in demanding applications such as aerospace, heavy-duty trucks, and oil and gas systems.
