Maclock Couplings

Maclock Couplings are a type of industrial coupling designed for quick, tool-free connection and disconnection of hoses and pipelines. Sometimes referred to as camlock or cam and groove couplings, these fittings use a cam arm mechanism to lock into place securely, creating a leak-free seal even under challenging operating conditions.

What sets Maclock Couplings apart is their high-performance design, which focuses on ease of use, reliability, and resistance to wear and corrosion. Constructed from top-grade materials such as stainless steel or aluminium, they are suited for high-demand environments where downtime and leakage are simply not an option.

By enabling rapid hose changes and minimising fluid loss, Maclock helps improve operational efficiency across countless industries. These quick release fittings are ideal for applications that require frequent maintenance or system configuration changes — allowing you to keep your processes running with minimal interruption.

Our range of Maclock Couplings includes a wide selection of configurations to meet your hose
connection requirements. Each type is designed to meet the demands of modern industrial workflows and is compatible with standard hose connection systems.

Common types include:

• Type A – Male adapter x Female BSP/NPT thread
• Type B – Female coupler x Male BSP/NPT thread
• Type C – Female coupler x Hose tail
• Type D – Female coupler x Female BSP/NPT thread
• Type E – Male adapter x Hose tail
• Type F – Male adapter x Male BSP/NPT thread
• Dust caps and dust plugs – For sealing ends when not in use

Each coupling is available in a range of sizes, usually from ½" to 6", to accommodate various flow rates and hose diameters. The cam arms ensure a tight, secure fit and can be operated quickly without tools — making these fittings ideal for rapid deployment in the field or factory floor.

We offer Maclock Couplings in different materials to suit a variety of working environments, including:

• Stainless Steel – For excellent corrosion resistance and food-safe applications
• Aluminium – Lightweight and cost-effective for general-purpose use
• Polypropylene and Brass – For specialised chemical and low-pressure applications

Thanks to their strength, versatility, and ease of use, Maclock Couplings are used in an incredibly wide range of industries and applications. From fluid transfer to dry bulk handling, they’re designed to maintain a secure seal while withstanding tough industrial conditions.

Typical uses include:

• Chemical and fluid transfer – Safe handling of solvents, acids, and chemicals
• Food and beverage production – Hygienic stainless-steel options for clean processing
• Agriculture and irrigation – Durable connections for water supply systems
• Construction and mining – Rugged couplings for high-flow hoses
• Marine and offshore operations – Corrosion-resistant fittings for saltwater exposure
• Pharmaceuticals and biotechnology – Reliable, sterile hose connections for cleanrooms
• Fuel and oil distribution – Fast and secure fittings for petroleum-based products

No matter the industry, these high-performance couplings ensure leak-free operation, reduce maintenance times, and improve safety across all hose-based systems.

Selecting the correct Maclock Coupling involves considering several key factors, such as:

• Hose diameter and flow rate
• Media type (liquid, gas, powder, corrosive, etc.)
• Pressure and temperature ratings
• Material compatibility (stainless steel, aluminium, etc.)
• Environment (indoor, outdoor, chemical exposure, marine, etc.)
• Frequency of use and disconnection requirements

If you're not sure which industrial coupling is the best fit for your application, our technical team is here to help. With years of experience supplying hose
connection systems across a wide range of sectors, we can guide you to the ideal configuration for your needs.
