China Bolt Hose Clamp - Industrial Grade Single Bolt High Pressure Hose Clamp

As a leading China bolt hose clamp factory in China, we produces durable stainless steel single bolt hose clamps. Engineered for the most demanding environments, our single bolt high pressure hose clamps provide exceptional clamping force for thick-walled hoses. Featuring a reinforced bolt and solid trunnions, these clamps are the go-to solution for high-vibration and high-pressure industrial fluid systems.

The Single Bolt Heavy Duty Clamp (also known as a Super Clamp) is designed for applications where standard worm drive clamps fail. With its robust construction and high-tensile bolt, it ensures a 360-degree leak-proof seal on suction and delivery hoses.

Key Features of this China Bolt Hose Clamp

Extreme Torque Capacity: The robust bolt allows for much higher tightening torque compared to standard clamps, ensuring a blow-off proof connection.

Reinforced Bridge: The bridge piece protects the hose from being pinched or damaged during high-pressure tightening.

Smooth Inner Band: Precision-finished edges and a smooth inner surface prevent hose abrasion.

Heavy-Duty Trunnions: Solid trunnions (not hollow) ensure the bolt doesn't bend or snap under extreme tension.

FAQ of Our China Bolt Hose Clamp Factory

Q1: How do I choose the right size for a Bolt Hose Clamp?

A: Unlike worm drive clamps, bolt clamps have a narrower adjustment range. You must measure the precise Outer Diameter (OD) of your hose when it is installed on the pipe or fitting.

Q2: Are your bolts Grade 8.8 or Grade 4.8?

A: For our carbon steel (W1) versions, we use Grade 8.8 high-tensile bolts to ensure they can handle the high torque required for industrial sealing.

Q3: Can these clamps be reused?

A: Yes, the high-quality stainless steel and robust bolt design allow for multiple installations and removals without losing clamping efficiency.

Q4: Do you offer custom band widths for special projects?

A: As a professional China bolt hose clamp manufacturer, we can customize band widths and thicknesses for bulk OEM orders to meet specific pressure requirements.
