Black American-Type Worm Drive Hose Clamp
A corrosion-resistant, adjustable hose clamp featuring a 12.7 mm band, worm-drive fastening mechanism and uniform black electrophoretic coating for industrial, automotive and equipment installation.
Reliable Fastening with a Uniform Black Finish
Designed for practical hose and tubing assembly, the clamp combines an adjustable worm-drive mechanism with a durable band structure and a clean, consistent surface finish.
Corrosion-Resistant Surface
The black electrophoretic coating forms a uniform protective layer that helps reduce surface oxidation in normal outdoor, equipment and workshop environments.
Adjustable Worm-Drive Fastening
The screw-driven housing allows controlled diameter adjustment and helps distribute clamping force around flexible hose and tubing connections.
Durable Band Construction
The 12.7 mm band provides a practical balance between flexibility, installation clearance and holding performance for general industrial applications.
Easy Field Installation
Cross-recessed or slotted screw-head options allow the clamp to be tightened, adjusted or removed with commonly available hand tools.
American-Type Hose Clamp Construction
This black American-type hose clamp uses a perforated metal band that passes through a compact screw housing. Turning the screw advances the band through the housing, allowing the clamp diameter to be adjusted around the hose connection.
Compared with a fixed-diameter clip, the worm-drive design offers greater installation flexibility and can compensate for small differences in hose outside diameter, fitting tolerances and assembly position.
- Perforated band engages directly with the worm-drive screw.
- Adjustable diameter simplifies inventory and installation.
- Compact housing fits common hose and pipe assemblies.
- Black finish provides a consistent industrial appearance.

How the Worm-Drive Mechanism Works
The perforations along the band act as gear teeth. When the screw is rotated, its thread engages the perforations and draws the band through the housing. This reduces or increases the clamp diameter without requiring a separate locking component.
- Screw rotation provides controlled diameter adjustment.
- Curved band wraps around the hose circumference.
- Housing maintains alignment between screw and band.
- Reusable construction supports maintenance and replacement.
What Problems Does This Hose Clamp Solve?
The product is intended to improve assembly consistency, simplify maintenance and secure flexible hose connections where a reusable adjustable clamp is preferred.
Loose Hose Connections
Provides adjustable circumferential pressure to help retain a hose on a properly matched barb, pipe or fitting.
Diameter Variation
Accommodates small dimensional differences between hoses, fittings and production batches without requiring an exact fixed-size clip.
Difficult Maintenance
The screw-operated design can be loosened and retightened during servicing, component replacement or equipment inspection.
Inconsistent Surface Appearance
A uniform black finish is suitable for equipment where the clamp must blend with black tubing, frames, engines or surrounding components.
Suitable for General Industrial Hose Connections
Black American-type hose clamps are commonly selected for equipment installations requiring easy adjustment, compact construction and a dark, corrosion-resistant surface finish.
Choose the Clamp Configuration for the Operating Environment
Band material and surface treatment should be selected according to humidity, chemical exposure, temperature, appearance and required service life.
Black-Coated Carbon Steel
A cost-effective choice for general equipment, automotive, workshop and indoor industrial applications.
Zinc-Plated Steel
Provides common-purpose corrosion protection and is widely used in industrial hose clamp production.
Stainless Steel Option
Suitable where improved moisture and corrosion resistance is required. The grade should be confirmed for the actual environment.

Black American-Type Hose Clamp FAQ
Technical and purchasing questions commonly raised when specifying this clamp for industrial hose connections.
Is the black surface electroplated or electrophoretically coated?
Based on the supplied product information, the black finish is more accurately described as an electrophoretic coating, also called e-coating. Final coating specifications should be confirmed before ordering.
What is the band width of this American-type hose clamp?
The shown product uses a 12.7 mm-wide band. The listed thickness is approximately 0.7 mm for the zinc-plated steel version and 0.6 mm for the stainless steel version.
Can the clamp diameter be customized?
Yes. DISLAB PRECISION can evaluate additional diameter ranges, band specifications and screw configurations according to the required hose outside diameter, drawing or physical sample.
Is the black coating suitable for outdoor use?
The coating improves general surface protection, but service life depends on humidity, salt exposure, chemicals, temperature and mechanical damage. For severe outdoor or marine environments, a suitable stainless steel configuration may be preferable.
Can this clamp be used for high-pressure hydraulic hoses?
A standard worm-drive hose clamp is generally intended for common hose and low- or moderate-duty connections. High-pressure hydraulic systems require fittings and retention components specifically engineered for the system pressure.
What information should be provided for a quotation?
Please provide the required diameter range, band material, band width and thickness, coating or finish, screw-head style, estimated quantity, packaging requirements and application environment.
