The recommended installation torque is ≥15N.m

The standard implemented by American clamps is: SAE J1508

Among them, TYPE F is a typical worm gear clamp in this implementation standard.

Has been designing and manufacturing high-quality hose clamp fastening products for various industrial and commercial pipe fittings application systems. Our team works closely with customers in various industrial markets-automobiles, locomotives, ships, mining, petroleum, chemical, pharmaceutical, communication equipment, food machinery, sewage treatment, construction engineering, agricultural machinery and other industries.

Use constant torque hose clamp on the heating and cooling systems. They are worm-drive and provide a series of spring washers. The constant torque hose clamp design automatically adjusts its diameter. It compensates for the normal expansion and construction of hose and tubing during vehicle operation and shutdown. Clamps prevent leakage and rupture problems caused by cold flow or changes in the environment or operating temperature.

Since the constant torque clamp is self-adjusting to keep a consistent sealing pressure, you don’t need to retorque the hose clamp regularly. Proper torque installation should be checked at room temperature.
