Single-Bolt Double-Band Heavy-Duty Hose Clamp
A heavy-duty pipe and hose clamp combining two parallel bands with a single M6 locking system. The double-band construction increases the contact area around the connection while the protective bridge and single-bolt mechanism provide practical fastening for industrial hose, drainage, irrigation, automotive and machinery applications.
Double-Band Contact with a Single-Bolt Locking Structure
The Single-Bolt Double-Band Heavy-Duty Hose Clamp is intended for industrial hose and pipe fastening where a wider clamping surface is preferred. Two parallel steel bands surround the connection while one M6 bolt controls the locking assembly.
The double-band arrangement spreads the clamping load across a broader contact area than a narrow single-band clamp. A protective bridge is positioned beneath the locking area to support the hose surface and reduce direct localized contact from the fastening mechanism.
The clamp is available in galvanized carbon steel, SS200/SS300-series stainless steel and SS316 configurations. Standard listed sizes cover approximately 35 mm to 200 mm connection diameters.

Built for Firm Fastening and Broad Hose Contact
The two-band structure and single-bolt locking assembly provide a practical combination of contact area, fastening strength and serviceability.
Double Band Design
Two parallel bands increase the contact area around the hose or pipe and help distribute the fastening load across a wider section of the connection.
Strong Clamping Force
The robust locking structure is designed for secure fastening where the connection may experience vibration, movement or pressure variation.
Protective Bridge
The formed bridge supports the area beneath the locking assembly and helps prevent the fastening mechanism from pressing directly into the hose surface.
Single-Bolt Installation
One M6 locking bolt simplifies adjustment compared with multi-bolt clamp structures and supports efficient installation and servicing.
M6 Bolt, Protective Bridge and Double-Band Construction
The clamp combines two 20 mm bands with a protective bridge, axle and single M6 locking point.
One Locking Point Controls the Double-Band Assembly
Tightening the M6 bolt closes the clamp around the installed hose or pipe connection. The bridge supports the locking area while both bands maintain contact around the circumference.
Details of the Double-Band Locking Assembly
Close-up views allow buyers to inspect the band edges, bridge geometry, locking area and stainless steel construction before selecting a specification.
What Problems Does This Double Band Clamp Help Solve?
The design addresses several practical issues encountered with demanding hose and pipe connections.
Concentrated Clamping Pressure
The two-band construction spreads the fastening load across a broader contact area, helping reduce pressure concentration at one narrow point of the hose.
Connection Movement and Vibration
The substantial band and locking structure help maintain mechanical retention on connections exposed to equipment movement and vibration.
Time-Consuming Multi-Bolt Adjustment
The single-bolt locking layout simplifies adjustment and servicing where a multi-bolt heavy-duty clamp is unnecessary.
Different Corrosion Environments
W1, W4 and W5 configurations allow industrial buyers to choose galvanized steel, standard stainless steel or SS316 according to service conditions.
Single-Bolt Double-Band Heavy-Duty Hose Clamp Specifications

Single-Bolt Double-Band Heavy-Duty Hose Clamp FAQ
Practical answers for industrial buyers comparing clamp design, materials, sizing and installation requirements.
Why does this clamp use two bands but only one bolt?
The two bands provide a broad contact area around the hose, while the single M6 locking mechanism controls the clamp assembly. This allows the design to combine double-band contact with relatively straightforward adjustment.
What is the purpose of the protective bridge?
The protective bridge sits beneath the locking area and supports the hose surface where the clamp closes. It helps prevent the locking components from concentrating directly against a small section of the hose.
What bolt is used on the standard sizes?
The supplied specification lists an M6 × 45 bolt across the standard clamping ranges shown from 35–40 mm through 195–200 mm.
What is the difference between W1, W4 and W5?
W1 uses galvanized steel for the listed clamp components. W4 uses SS200/SS300-series stainless steel, while W5 uses SS316 for applications requiring greater corrosion resistance.
Is this the same as a Double-Bolt Heavy-Duty Hose Clamp?
No. The two products use different locking structures. This product has a double-band design controlled by a single locking bolt, while a Double-Bolt Heavy-Duty Hose Clamp uses two separate bolt fastening points.
Can the clamp be used for irrigation and drainage hoses?
Agriculture, irrigation, drainage and sludge suction are among the listed applications. The selected clamp size and material should still match the actual hose, fitting and operating environment.
How should I select the correct size?
Measure the outside diameter of the assembled hose and fitting. Then select the clamp range that contains that diameter rather than choosing only by the nominal hose bore.
What should be included in an RFQ?
Send the installed outside diameter, required clamp range, W1/W4/W5 material, order quantity, application, destination country and any OEM or packaging requirements.
