End Caps

End Caps are threaded pipe fittings used to close off the end of a pipeline or unused outlet. Manufactured from malleable iron and typically supplied with BSP female threads, they provide a strong, leak-resistant seal for a wide range of mechanical, fire protection and industrial applications.

 
They are commonly used in systems where pipework needs to be safely terminated, isolated or left ready for future extension.

Key Features

• Female BSP threaded design for secure sealing 
• Manufactured from durable malleable iron 
• Provides a reliable pipe termination point 
• Suitable for pressure and non-pressure systems 
• Compatible with steel pipe and threaded fittings 
• Available in corrosion-resistant finishes

Product Description

End Caps are designed to seal the end of a threaded pipe run, preventing the escape of fluids or gases and protecting the system from contamination. They are typically manufactured from malleable cast iron, which provides a strong yet slightly ductile structure, reducing the risk of cracking under tightening or pressure fluctuations.

 
Most malleable iron end caps feature BSPT (British Standard Pipe Taper) female threads, allowing them to be screwed directly onto male threaded pipe ends. When installed with appropriate sealing compounds or PTFE tape, they create a secure and reliable seal suitable for a wide range of service conditions.

 
These fittings are widely used across plumbing, heating, fire sprinkler and industrial pipework systems, where they are often used to terminate unused outlets, isolate sections of pipework, or seal systems during testing and maintenance. They are also commonly specified in gas, oil and compressed air applications due to their robustness and reliability.

 
Manufactured to recognised standards such as BS EN 10242, malleable iron end caps are designed for consistent performance and compatibility with standard steel pipe systems. They typically offer pressure ratings up to around 25 bar, depending on specification and installation conditions.

 
Available in Black (self-colour) for internal use or systems that will be painted or coated after installation, and Hot Dip Galvanised (HDG) for enhanced corrosion resistance in external or more aggressive environments, they provide flexibility across a wide range of applications.

Applications

Ideal for fire sprinkler systems, plumbing, heating, gas, oil, compressed air and general industrial pipework where a secure threaded termination or isolation point is required.
