Frequently Asked Questions
What is a heavy duty single bolt hose clamp?
A heavy duty single bolt hose clamp uses a wide stainless steel band with a single large-diameter bolt for high-torque tightening. The wider band distributes pressure over a larger hose surface area than standard worm drive clamps, making it suitable for thick-wall industrial hoses.
What size range does it cover?
Available in sizes covering hose outer diameters from approximately 40 mm to 200 mm (1.5 inch to 8 inch), addressing medium to large industrial and agricultural hoses.
What torque can be applied?
The single large-format bolt allows significantly higher tightening torque than a standard worm drive clamp — typically 8–20 Nm depending on size — providing superior sealing force on thick-wall rubber and PVC hoses.
What material is available?
Available in stainless steel SS304 and SS316 for corrosion-critical environments, or in galvanized steel for cost-sensitive general industrial applications.
What applications use this clamp?
Used for clamping thick-wall rubber suction hoses, discharge hoses, industrial PVC hoses, mining hoses, pump connections, and agricultural irrigation hoses where high sealing force is required.
What is the minimum order quantity?
Standard MOQ is 500 pieces per size. Contact our sales team for pricing on large project quantities.
