Frequently Asked Questions for

Constant Torque Heavy Duty Worm Drive Clamp

The Constant Torque Heavy Duty Worm Drive Clamp is designed for heavy-duty applications where fluctuations in pressure and temperature can affect the hose diameter. Its spring action compensates for these variations, preventing loosening or loss of clamp load.

The Belleville washer stack compensates for pressure and temperature variations by maintaining consistent tension. This ensures a secure grip on the hose, eliminating the risk of loosening or seepage due to joint diameter changes.

These clamps are made using high-quality materials, including: ● SS300 and SS316 grade stainless steel for high durability. ● SS410 grade or plated carbon steel screws. ● Zinc-plated options for global export standards. The SS316 option is specifically suitable for marine applications.

The clamp supports installation torque up to 8.5 Nm and an ultimate torque of up to 11.5 Nm, ensuring robust performance for heavy-duty applications.

The liner prevents the clamp's perforations from coming into direct contact with the hose, avoiding hose damage or "biting" even at high installation torque levels. This enhances the lifespan of the hose and ensures leak-proof performance.

These clamps are ideal for various applications, including: ● Automotive and engine systems. ● Cooling systems. ● Marine environments. ● Oil and gas industry applications.

The Jolly Constant Torque Worm Drive Clamps are designed to meet SAE standards, ensuring consistent quality and performance for heavy-duty applications.
