Technical Specifications:

These inline valves are available in four sizes to suit different applications:

• 4mm valve: Requires flexible pipe with 4mm internal diameter
• 13mm valve: Requires flexible pipe with 13mm internal diameter
• 19mm valve: Requires flexible pipe with 19mm internal diameter
• 25mm valve: Requires flexible pipe with 25mm internal diameter

Material: UV-stabilised polypropylene

Pressure rating: Suitable for low-pressure applications only, 300kpa max working pressure

Connection type: Barbed fittings

Applications:

• Garden irrigation systems
• Hydroponics setups
• Aquarium and marine tank water management
• Pond systems
• Low-pressure air distribution (bubblers, aeration)

Installation Notes:

For optimal performance, ensure you select the correct valve size to match your pipe's internal diameter. The barbed connection provides a secure fit when used with flexible piping that can stretch over the barb. For additional security, especially in higher pressure applications (while still within the low-pressure rating), jubilee clips or similar fasteners can be used to strengthen the connection.

Usage Limitations:

These valves are specifically designed for low-pressure applications and are NOT suitable for high-pressure or mains water connections. While they are excellent for aquarium projects and low-pressure air applications like pond bubblers, they should not be used with high-pressure air systems.
