John Guest

John Guest nylon pipe is a lightweight, flexible alternative to metal air pipework, purpose-designed for compressed air ring mains and pneumatic distribution systems.

Manufactured from durable nylon, this pipe is corrosion-resistant, easy to handle on site and quick to install. It’s particularly well suited to workshops and factories where clean, dry air is required without the higher pressure demands of heavy industrial systems.

Key highlights

• Designed specifically for compressed air applications
• Lightweight and flexible for easier routing and faster installation
• Suitable for up to 15 bar (temperature dependent)
• Operating temperature range -20°C to +65°C
• Compatible with John Guest push-fit fittings
• Available in 12mm to 28mm diameters in 3-metre lengths

Nylon pipe requires allowance for thermal expansion, making correct clipping and expansion bends important on longer runs. Due to its bespoke, cut-to-length nature, all sizing and application details should be confirmed before ordering.

Best for: standard pneumatic systems, workshops, smaller factories and applications where flexibility and ease of installation are priorities.

John Guest aluminium pipe is designed for higher-performance compressed air systems where greater pressure capability and flow rates are required.

Constructed from powder-coated aluminium and manufactured to BS EN 755-1, this pipe combines strength, durability and corrosion resistance with a lightweight profile that’s far easier to install than traditional steel pipework.

Key highlights

• High-pressure capability up to 20 bar (temperature dependent)
• Powder-coated aluminium for long service life
• Operating temperature range -20°C to +65°C
• Optimised for air ring main installations
• Compatible with John Guest push-fit fittings
• Available in 15mm to 28mm diameters in 3-metre lengths

Aluminium pipe installations should allow for thermal expansion using correct spacing, clips and expansion bends. When installed correctly, it delivers excellent airflow performance for demanding industrial environments.

Best for: high-demand compressed air systems, larger factories, long pipe runs and applications with higher flow or pressure requirements.

John Guest push-fit fittings are at the heart of the system, providing fast, secure and demountable connections without tools, adhesives or hot works.

Manufactured from high-quality acetal copolymer, these fittings use a precision collet and O-ring sealing system to grip the pipe firmly without deformation, ensuring airtight, repeatable connections across a wide range of applications.

Key features

• Tool-free, push-fit installation
• Secure mechanical grip with airtight O-ring seal
• Working temperature -20 °C to +70 °C
• Pressure rated up to 10 bar
• Compatible with nylon and aluminium pipe
• Sizes 12mm - 22mm push-fit, 28mm twist-and-lock
• Fully demountable and reusable

Available in straight connectors, elbows, tees, reducers, adaptors, end stops and specialist components, these fittings make system installation, modification and maintenance fast and cost-effective.

For applications requiring added strength and durability, John Guest brass push-fit fittings combine robust brass construction with the same proven push-fit technology.

Manufactured in the UK, these fittings provide excellent flow characteristics and dependable sealing for compressed air and pneumatic systems operating in more demanding environments.

Key features

• Durable brass body for enhanced strength
• Push-fit, demountable design
• Suitable for compressed air up to 10 bar
• Operating temperature -20°C to +70°C
• Compatible with nylon and aluminium pipe
• Also suitable for inert gases, vacuum and potable liquids

Typical uses: industrial compressed air systems, pneumatic control installations and workshop air drops where robustness is essential.
