High-Torque Worm-Drive Hose Clamp with Electroplated Black Finish
The DISLAB PRECISION high torque worm drive hose clamp is designed for industrial hose and tube connections requiring firm tightening, repeat adjustment and a secure fit. Its reinforced housing, worm-drive screw and precision-slotted band provide controlled engagement across a range of connection diameters.
Multiple band widths and thicknesses for different connection requirements.
Confirm the exact working diameter range when submitting an inquiry.
SS200/SS300-series component options or an SS316 construction.
Suitable for connections that may require adjustment after installation.
Secure, Adjustable Clamping for Industrial Connections
This high torque worm drive hose clamp combines a wide perforated band with a reinforced screw housing. Turning the screw advances the band through the housing, allowing the clamp diameter to be adjusted around a hose, tube or connection point.
The reusable design is useful where a connection may need to be inspected, repositioned or re-tightened. It can also be adjusted after dimensional changes caused by temperature variation or normal hose compression.
- Firm mechanical tightening through a worm-drive screw
- Adjustable perforated band for accurate diameter control
- Reusable construction for maintenance and servicing
- Black electroplated surface for industrial applications
Four Main Components Working as One Clamping System
The clamp structure consists of a screw, housing, saddle and perforated band. Each part supports the tightening action and helps maintain stable engagement around the connection.
Worm-Drive Screw and Housing
The screw transfers installation torque into band movement. The surrounding housing keeps the screw aligned and supports controlled tightening.
Saddle and Perforated Band
The saddle supports the housing against the band, while the slots engage with the screw thread to provide smooth diameter adjustment.
Band Dimensions and Material Configurations
Select the band configuration and material class according to the connection diameter, operating environment and corrosion exposure.
| Specification | Available Details |
|---|---|
| Band Width × Thickness | 12.7 × 0.6 mm |
| Band Width × Thickness | 14.2 × 0.6 mm |
| Band Width × Thickness | 15.8 × 0.8 mm |
| Clamp Diameter | 32 mm and above |
| Drive Type | Worm-drive screw adjustment |
| Surface Appearance | Black electroplated finish |
| Material Class | Band | Screw | Housing | Saddle |
|---|---|---|---|---|
| W4 | SS200/SS300 Series | SS200/SS300 Series | SS200/SS300 Series | SS200/SS300 Series |
| W5 | SS316 | SS316 | SS316 | SS316 |
Exact diameter range, component material combination and finish requirements should be confirmed before ordering. Material grade alone does not establish compliance with a specific industry or food-contact standard.
Designed for Controlled Tightening and Repeat Adjustment
High-Torque Housing
The enlarged housing supports the screw during tightening and helps transfer torque into consistent band movement.
Electroplated Black Finish
The black electroplated surface provides a uniform industrial appearance and supports surface protection in suitable operating environments.
Precision-Slotted Band
The evenly arranged slots provide positive engagement with the worm-drive screw, allowing smooth tightening and diameter adjustment.
What This High-Torque Clamp Helps Solve
The product is intended for industrial buyers who need an adjustable fastening method that can be installed, inspected and re-tightened without replacing the entire clamp.
Insufficient Tightening Control
The worm-drive mechanism allows gradual adjustment instead of relying on a fixed, non-adjustable connection.
Changes After Temperature Cycling
The clamp can be re-tightened when a hose expands, contracts or settles after installation.
Frequent Clamp Replacement
Its reusable construction allows removal and reinstallation during routine maintenance or equipment servicing.
Inconsistent Diameter Adjustment
The perforated band and worm-drive screw provide controlled engagement across the clamp’s working range.
Reliable Clamping for Hose, Machinery and Fluid Connections
High torque worm drive clamps can be considered for hose and tube connections used in automotive systems, machinery, fluid-transfer equipment and general industrial assemblies.
Material selection should reflect the surrounding environment. W5 SS316 construction may be considered where increased corrosion resistance is required, while the final choice should be based on operating conditions and customer specifications.
Information to Prepare Before Requesting a Quotation
Clear operating data helps identify the appropriate diameter, band configuration and material class.
Provide the outside diameter of the hose or assembled connection, not only the nominal hose size.
Include temperature range, moisture exposure, chemicals and other conditions that may affect material selection.
State the required quantity, band dimensions, material class, packaging needs and delivery destination.

High-Torque Worm-Drive Hose Clamp FAQ
Practical information for industrial purchasers, distributors and equipment manufacturers.
What diameter range is available?
The available information indicates sizes starting from 32 mm. The exact minimum and maximum working diameter should be confirmed for the selected band width and order specification.
What is the difference between the W4 and W5 versions?
The listed W4 configuration uses SS200/SS300-series materials for the band, screw, housing and saddle. The listed W5 configuration uses SS316 for all four components.
Can the clamp be re-tightened after installation?
Yes. The worm-drive mechanism allows the clamp to be adjusted and re-tightened, including after hose compression or dimensional changes caused by temperature variation.
Which band widths and thicknesses are listed?
The listed combinations are 12.7 × 0.6 mm, 14.2 × 0.6 mm and 15.8 × 0.8 mm. Selection should be based on connection diameter and operating requirements.
Is the black finish suitable for every corrosive environment?
No finish should be selected by appearance alone. Provide details about chemicals, moisture, salt exposure and operating temperature so the material and surface treatment can be reviewed for the intended environment.
Can this clamp be used on food-processing or marine equipment?
These are listed application areas, but suitability depends on the selected material, cleaning process, corrosion exposure and the customer’s technical or regulatory requirements. SS316 material alone does not automatically establish food-contact or industry compliance.
