Frequently Asked Questions
What is an American type hose clamp?
An American type hose clamp (also known as a worm drive clamp or SAE hose clamp) consists of a stainless steel or galvanized steel band with a worm-gear screw that tightens around a hose to create a secure, leak-free connection.
What standards do the American type hose clamps meet?
Sunhose American type hose clamps are manufactured to SAE J1508 standards, ensuring compatibility with global automotive, industrial, and agricultural applications.
What materials are available?
Available in all stainless steel (SS304 or SS316), stainless band with zinc-plated screw, and galvanized steel. All stainless construction (W4) is recommended for marine, chemical, and food-processing environments.
What size range is covered?
Clamp range covers approximately 8 mm to 270 mm (5/16 inch to 10-5/8 inch) through multiple series. Each clamp has a clamping range overlap with adjacent sizes for complete coverage.
What is the maximum torque for tightening?
Typical torque is 2–4 Nm depending on clamp width and size. Over-tightening can cut the hose — always follow the torque specification for the hose material being clamped.
Can American type clamps be reused?
Yes, worm drive clamps can generally be reused if they are not corroded or deformed. However, for critical pressure applications, replacing clamps when reassembling is recommended best practice.
What is the minimum order quantity?
Standard MOQ is 1,000 pieces per size. Mixed sizes within the same material grade can be combined to reach the MOQ.
