Double Wire Bolt Hose Clamp
An adjustable double wire hose clamp designed for securing flexible hose and corrugated tubing with a compact bolt-and-nut tightening mechanism. Two round steel wires distribute the clamping load around the hose while the smooth wire profile helps reduce sharp contact with the hose surface.
Adjustable Double Wire Clamping for Flexible Hose
The Double Wire Bolt Hose Clamp, also commonly called a double wire hose clip, uses two parallel round steel wires instead of a flat metal band. This gives the clamp a compact profile while maintaining secure contact around flexible hose and tubing.
The round wire edges are smooth and contain no punched slots or sharp perforations. This makes the design particularly useful where the hose surface should not be exposed to the edges of a conventional perforated band.
Clamp diameter is adjusted through a threaded bolt, square nut and washer assembly. Loosening the bolt opens the clamp for installation; tightening the bolt reduces the diameter and applies mechanical clamping force around the hose connection.
Double Wire, Bolt, Square Nut and Washer
The clamp has a straightforward mechanical structure that allows the effective diameter to be adjusted without a complex housing or worm-drive mechanism.
Simple Mechanical Diameter Adjustment
Turning the screw changes the distance between the fastening points and therefore the clamp diameter. The square nut prevents unwanted rotation during adjustment, while the washer supports the tightening assembly.
Why Use a Double Wire Hose Clamp?
The clamp combines a simple screw-adjusted structure with smooth round-wire contact around the hose.
Double Wire Construction
Two parallel steel wires provide the clamping structure and maintain contact around both sides of the hose connection.
Smooth Round-Wire Edges
The round wire profile has no perforated band openings and avoids sharp stamped edges directly contacting the hose surface.
Screw-Adjusted Diameter
The clamp can be opened, positioned and tightened by adjusting the bolt, making installation and replacement straightforward.
Multiple Wire Diameters
Wire diameter increases with clamp size, with available specifications ranging from approximately 1.4 mm to 3.0 mm.
What Problems Does a Double Wire Clamp Help Solve?
The wire construction is particularly useful where hose geometry or service requirements make a conventional perforated-band clamp less attractive.
Sharp Band Contact
Round steel wire provides a smooth contact profile without the punched slots and stamped edges found on many worm-drive hose clamps.
Corrugated Hose Geometry
Double wire construction can fit naturally around some corrugated and ribbed hose profiles where the wires can sit alongside the hose ribs.
Limited Installation Space
The clamp uses a compact wire body rather than a broad metal band, which can be useful where the available fastening area is relatively narrow.
Different Corrosion Requirements
W1 galvanized steel and W4 stainless steel configurations allow buyers to select the material according to the intended environment.
Galvanized Steel and Stainless Steel Versions
Different materials and surface finishes are available to match general industrial, indoor and corrosion-sensitive applications.

Where Double Wire Hose Clamps Are Used
The wire clamp design is commonly used on flexible and corrugated hose connections where compact size and straightforward screw adjustment are important.
Pumps and Fluid Equipment
Suitable for compatible flexible hose connections around pumps and auxiliary fluid-handling equipment.
Housings and Filters
Used to secure flexible hoses to filter housings, connectors and similar equipment interfaces.
Corrugated Hose
The twin round wires can work effectively with certain ribbed and corrugated hose profiles when the clamp dimensions match the hose geometry.
Appliances and Equipment
Commonly used on suitable appliance, machinery and general equipment hose connections requiring an adjustable wire clamp.
How to Select a Double Wire Bolt Hose Clamp
Correct selection depends on the assembled hose diameter, required wire size, material and fastening configuration.
Measure the outside diameter after the hose has been installed over the fitting rather than selecting only from the nominal hose bore.
Use the galvanized W1 configuration for general applications or specify W4 stainless steel where the project requires stainless components.
Wire diameter varies according to size and material. Larger clamps typically use heavier wire to maintain the required clamp structure.
Confirm that the round-wire geometry is suitable for the hose profile, particularly when fastening corrugated or ribbed tubing.
M5, M6 and M8 screw configurations are listed across the range. Specify the required clamp size and material before production.
Include expected order quantity, repeat demand, packaging, labeling and other sourcing requirements with your RFQ.

Double Wire Hose Clamp FAQ
Practical answers for buyers comparing double wire clamps, conventional hose clamps and material options.
Is a Double Wire Hose Clamp the same as a Double Wire Hose Clip?
Yes. Both names are commonly used for this general clamp design. DISLAB PRECISION uses “Double Wire Bolt Hose Clamp” on this page to describe the double-wire structure together with its screw-adjusted fastening system.
Why use round wire instead of a flat perforated band?
Round wire provides a smooth contact profile without punched slots or stamped band edges. It can also suit certain corrugated hose profiles where the wire geometry matches the hose surface.
What is the difference between W1 and W4?
W1 uses galvanized steel for the wire, bolt, square nut and washer. W4 uses SS200/SS300-series stainless steel for the listed components.
What sizes are available?
The supplied standard range starts at 8–12 mm and extends to 125–130 mm. Wire diameter and screw size change as the clamp diameter increases.
What screw sizes are used?
Depending on clamp diameter and material configuration, the range includes M5, M6 and M8 screws in different lengths.
Is this clamp suitable for corrugated hose?
It can be suitable for certain corrugated hose profiles because the parallel wires may sit close to the hose ribs. The hose outside diameter and rib geometry should be checked before selecting the clamp.
How should I measure the correct clamp size?
Measure the outside diameter of the hose after it has been installed over the fitting. Choose a clamp range that includes this assembled diameter.
What information should I send for a quotation?
Send the required clamp diameter, W1 or W4 material, quantity, hose or application information and destination country. Photos, drawings or an existing sample specification are also helpful for replacement sourcing.
