Our American style worm gear hose clamps are precision-engineered with a 12.7mm (1/2") wide band and 0.6mm thickness for optimal strength-to-weight ratio. Available in three material grades: carbon steel for general applications, semi-stainless for moderate corrosion resistance, and full stainless steel (AISI 304/316) for harsh environments. The innovative worm drive mechanism provides smooth and incremental adjustment.
This design meets SAE J1508 and ISO 9001 standards, making it ideal for demanding applications in automotive, marine, and industrial fluid systems where reliable sealing under high pressure is critical. The perforations also allow for visual inspection of proper clamp engagement.
