A One Bolt Heavy Duty Hose Clamp is a robust clamping device designed to create a secure, high-pressure seal on hoses and ducts. As the name implies, it is characterized by its use of a single, large-diameter bolt as its tightening mechanism, distinguishing it from standard worm-drive clamps (which use a screw) and T-bolt clamps (which use a dedicated T-shaped bolt). This design offers a superior balance of very high clamping force, durability, and ease of installation for a wide range of heavy-duty industrial applications. And our hose clamp price is very competitive.
Material:
W1 - All parts carbon steel with zinc plated.
W2 - Band and bridge stainless steel 201 or 304, bolt, sleeve and shaft carbon steel with zinc/nickel plated
W4 - All parts stainless steel 201 or 304.
W5 - All parts stainless steel 316


Key Design Features
Single Bolt Mechanism: The clamp features one large, hex-head bolt that threads directly into a welded nut on the clamp's housing or frame. This large bolt can handle high torque, allowing for immense tightening force.
Heavy-Gauge Band: The band is made from a much thicker and wider strip of steel (typically stainless or carbon steel) compared to standard clamps. This prevents the band from stretching or warping under extreme pressure.
Reinforced Housing: The housing that contains the bolt and the end of the band is heavily reinforced, often by welding or forging, to withstand the stress exerted by the large bolt without deforming.
Smooth Inner Band: Many heavy-duty clamps have a smooth inner surface to prevent damage to the hose being clamped, which is crucial for silicone or other soft hose materials.

Typical Applications
This clamp is a workhorse in industries where hose failure is not an option:
Industrial Manufacturing: Securing large coolant, air, hydraulic, and abrasive material hoses.
Power Generation: Used on cooling and exhaust systems.
Marine and Offshore: Securing hoses on ships and platforms, especially in stainless steel to resist saltwater corrosion.
Agriculture: On heavy machinery for irrigation, fuel, and hydraulic lines.
HVAC and Ducting: Connecting flexible ducts in commercial and industrial ventilation systems.

Q1: How do you determine the price of hose clamps?
A: Our pricing is based on three main factors: Material grade (e.g., SS316 is higher than SS304), Bandwidth/Size, and Order Volume. Bulk wholesale orders qualify for significant tiered discounts.
Q2: What is the Minimum Order Quantity (MOQ) for the best price?
A: To provide the most competitive factory pricing, our standard MOQ usually starts at 1,000 pieces per size. However, we do support smaller trial orders for new clients.
Q3: Can I get a sample before placing a bulk order?
A: Yes! We provide free standard samples for quality testing. You only need to cover the express shipping cost, which is refundable upon your first mass production order.
Q4: Do you provide a 2026 Price List PDF?
A: Because raw material costs (like stainless steel) fluctuate, we provide custom real-time quotes. Please send inquiry to receive our latest pricing within 24 hours.
