Camlock vs Threaded Fittings: What’s the Difference?

When it comes to connecting hoses and pipework in industrial fluid systems, choosing the right type of fitting can make a huge difference in performance, safety and efficiency. Among the most common options are camlock and threaded fittings.

But which is best for your application and what’s the real difference between camlock and threaded fittings?

What Are Threaded Fittings?

Threaded fittings are one of the oldest and most widely used connection types in fluid handling systems. They connect components using male and female thread which screw together to form a tight seal.

In the UK and much of Europe, the most common thread standard is BSP (British Standard Pipe), while in North America, NPT (National Pipe Thread) is more common.

Threaded fittings are often used in fixed installations, such as static pipework or systems where connections don’t need to be changed frequently. They’re reliable, strong and suitable for high-pressure applications provided they are installed correctly with the right sealing method.

Advantages of Threaded Fittings:

Simple, well understood design
Strong and secure connection
Suitable for high pressure and static systems
Easy to source
Standardised in BSP sizes across the UK

Disadvantages of Threaded Fittings:

Slower to install or remove, often requiring tools
Risk of thread damage or leaks if over tightened
Not ideal for applications requiring frequent disconnection

What Are Camlock Fittings?

Camlock couplings are a quick connect solution used widely across industries such as food processing, chemicals, agriculture and oil transfer.

A camlock system typically consists of two parts; a male adaptor and a female coupler.

To connect, you simply insert the adaptor into the coupler and close the cam arms, the locking motion creating a tight seal. No tools are usually required, making camlocks ideal for hose systems that need to be connected and disconnected quickly and safely.

Advantages of Camlock Fittings:

Rapid connect and disconnect without tools
Reliable and leak resistant when properly sealed
Ideal for flexible hose systems and mobile setups
Easy to maintain

Disadvantages of Camlock Fittings:

Not typically rated for high pressures compared to threaded connections
Cam arms and gaskets can wear down over time
Require space for the cam arms to operate
Must ensure compatibility between coupling halves

Camlock vs Threaded Fittings: Head-to-Head comparison

Feature	Camlock Fittings	Threaded Fittings
Connection Speed	Quick, no tools needed	Slower, screw connection
Ease of Use	Simple lever operation	Requires tools
Leak Resistance	Reliable when gasket is intact	Depends on thread but typically a strong seal
Pressure Rating	Moderate	Typically higher
Ideal For	Flexible systems, mobile systems	Static pipework, high pressure systems
Maintenance	Gaskets and coupling wear down over time	Check for thread wear and leaks
Common Materials	Aluminium, stainless steel, polypropylene	Brass, stainless steel
Typical UK Standard	Universal camlock sizes	BSP thread standard

In short, camlock vs threaded fittings boils down to flexibility and frequency of use. Camlocks work best when you need a quick, tool-free connection in your systems. Threaded fittings win in fixed or high pressure systems where disconnections are rare.

When to Choose One Over the Other

Choosing between camlock and threaded fittings depends on your application requirements:

Choose Camlock Fittings If:

You frequently connect or disconnect hoses
You need to change fluids or clean lines regularly
Your system involves flexible hoses or portable equipment
You want a fast, secure connection

Examples:

Tanker loading/unloading systems
Industrial cleaning setups
Food and beverage hose lines
Agricultural irrigation or chemical transfer

Choose Threaded Fittings If:

Your pipework is static and connections are permanent
You need high pressure or rigid system integrity
Your installation is compact with limited space for cam arms
You want a traditional, proven connection method

Examples:

Fixed plant pipework
Compressed air or gas systems
High pressure hydraulic applications
Building services or plumbing networks

Installation and Maintenance Tips

Threaded Fittings:

Always check that male and female threads match.
Avoid overtightening as it can damage the threads or fittings.
Inspect for corrosion, cross threading or leaks periodically.

Camlock Fittings:

Check that the coupler and adaptor sizes match.
Inspect gaskets and replace if worn, cracked or compressed.
Keep cam arms clean and lubricated for smooth locking.
Ensure both halves are made from compatible materials to avoid galvanic corrosion.

Proper maintenance ensures longer life, fewer leaks and safer operations across both fitting types.

Both camlock and threaded fittings serve important roles in fluid transfer systems and the best choice depends on your system’s priorities.

For speed, simplicity and versatility, camlock fittings are ideal especially in hose based systems where quick connection and disconnection are routine. For permanent, high-pressure or rigid installations, threaded fittings offer strength and reliability.

When comparing camlock vs threaded fittings, consider not just the connection type but also the materials, environment and maintenance requirements. In many cases, a hybrid approach using camlocks at the hose ends and BSP threaded connectors at the pipework delivers the best of both worlds.
