SAE J1508 is an SAE International standard that establishes comprehensive specifications for thirty-two distinct types of hose clamps—including worm-drive and constant-torque designs—for use in automotive applications. The standard defines stringent requirements for materials, dimensional characteristics, and performance criteria, ensuring compliance with OEM-level reliability for critical fluid and gas handling systems. These clamps are engineered to perform in applications such as coolant, fuel, oil, vacuum, and emission systems, providing assured sealing integrity, vibration resistance, and durability under vehicle operating conditions.
High torque ss worm drive hose clamp is one type of SAE J 1508 hose clamps. The 12.5mm Power Lock SS worm drive hose clamp—also referred to as a high-torque clamp—incorporates an integrated structure that combines a stainless steel band with a protective metal housing. Key components include a high-strength stainless steel band, a stamped metal housing, and a worm gear adjustment mechanism. The housing fully encloses the fastening area, significantly improving torque capacity while delivering enhanced mechanical protection.

Material:
W4 - All parts SS304
the W4 high-torque clamp delivers outstanding corrosion resistance, exceptional strength, and long-term durability. The use of SS304 ensures reliable performance in harsh environments, while its high tensile strength effectively resists deformation under pressure. This results in reduced maintenance needs, minimized downtime for inspection or replacement, and greater cost efficiency over the product lifecycle.
Application:
Automotive & Transportation: Ideal for securing coolant, fuel, and power steering hoses in cars, trucks, buses, and heavy machinery. Its high torque capability and vibration resistance make it perfect for high-performance and racing vehicles.
Marine & Offshore: The 100% stainless steel construction provides excellent corrosion resistance against saltwater, making it the preferred choice for engine cooling systems, through-hull fittings, and other critical connections on boats, yachts, and offshore platforms.
Industrial Manufacturing: Used extensively in plant machinery, hydraulic systems, pneumatic lines, and processing equipment. It ensures leak-proof seals for hoses carrying water, steam, oils, chemicals, and other fluids under high pressure.
