Aluminum Square Flange to Male Cam Coupler
Reducer Square Flange × Male Camlock Connection Solution for Fuel & Industrial Fluids

The aluminum square flange to variable male cam coupler is a transitional connection component designed to convert square flange pipelines directly to different sizes of male camlock couplers. In the industry, this product is commonly referred to as a square flange camlock adapter, flange to male cam coupling, or reducer flange cam adapter.

In international markets, this product is known by different names depending on the region. For example, it is referred to as a square flange to male cam adapter in Spanish-speaking countries, a square flange to quick coupling adapter in German-speaking markets, a square flange transition coupling in French usage, and a square flange male cam connector in Italian industrial applications.

Thanks to its compact structure and flexible size configuration, this series is widely used in fuel transfer systems, industrial fluid handling, chemical process pipelines, and mobile hose assemblies, especially in applications requiring fast connection and precise alignment.

Material and Structural Advantages
Aluminum Alloy Body
Manufactured from high-quality aluminum alloy, this coupler combines high strength with reduced weight. It offers excellent corrosion resistance and is easy to install and maintain, making it suitable for demanding industrial environments.

Square Flange Interface
The flange end features a square flange design that complies with GB standard dimensions, ensuring secure and reliable bolted connections.

Male Camlock Outlet
The male cam interface is precisely machined to ensure full compatibility with standard female camlock couplings, providing a stable and dependable connection.

Reducer Transition Design
The flange size and male cam size can be different, allowing smooth transitions between pipeline diameters while optimizing overall system layout and flow efficiency.

Working Pressure Rating
Rated for a working pressure of 0.6 MPa, suitable for most fuel and industrial liquid transfer applications.

Customizable Flange Standards
Flange standards and dimensions can be customized according to project requirements, supporting multi-region and multi-system applications.

Typical Applications
Fuel Transfer Systems
Widely used in refineries, oil depots, tanker trucks, and loading arms where flange-to-hose connections are required.

Industrial Liquid Pipelines
Suitable for lubricating oil, diesel, and various industrial fluid transfer systems.

Chemical and Process Systems
Ideal for non-corrosive or mildly corrosive process liquids in industrial pipeline installations.

Temporary and Mobile Pipelines
Commonly applied in modular or detachable systems where fast installation and adjustment are required on-site.

Export-Oriented Engineering Projects
Well-suited for international projects that use GB standard square flanges combined with camlock coupling systems.
