Comprehensive Buyer’s Guide for the Screw-FIX Joiner - Ø 150
When it comes to ensuring a safe and efficient chimney system, selecting the right accessories is crucial. The Screw-FIX Joiner - Ø 150 is a vital component for those using MI-FLEX 316 and 904 multi-fuel flexible flue liners, offering reliability and robust performance that you can depend on.
Understanding the Product
The Screw-FIX Joiner - Ø 150 is meticulously engineered to connect two sections of a flue liner. This functionality is critical when the overall chimney liner exceeds the maximum flex available. Crafted from 316L stainless steel with a natural finish, the joiner is designed to withstand extreme operating temperatures of up to 600°C, making it ideal for various fuel types including wood, oil, gas, and smokeless coal. Additionally, its compliance with Building Regulations Document J and CE/HETAS approval make it a trusted choice in the UK market.
Key Advantages
- Reliable Performance: The secure connection provided by the joiner ensures that your flue system operates efficiently, reducing the risk of air leaks or heat loss. This stability is central to maintaining a safe environment within your property.
- High Temperature Tolerance: With a temperature rating of up to 600°C, the joiner is capable of handling high heat outputs, ensuring safety and longevity even during demanding usage scenarios.
- Durability: Made from high-grade 316L stainless steel, the joiner offers a long service life, resistant to corrosion and wear. This durability makes it a cost-effective long-term investment.
- Compliance & Safety: Meeting all relevant UK building regulations and safety standards, this product offers peace of mind, knowing that you are installing a component that is fully approved for modern chimney systems.
Installation Instructions
Installation of the Screw-FIX Joiner should only be performed in a completely enclosed masonry chimney to comply with Building Regulations Document J. Begin by preparing your work area and ensuring that all necessary tools and safety equipment are at hand. Align the flue liner sections carefully, and securely fix the joiner to create a seamless joint. Regular maintenance is key; a thorough sweep using non-chemical cleaners is recommended at least once a year—increasing to twice yearly for systems running solid fuel. Avoid using mild steel tools to preserve the integrity of the stainless steel.
Optional Accessories and System Enhancements
While the Screw-FIX Joiner is essential for connecting flue liner sections, you may also want to consider additional accessories to optimise your chimney system. Options such as sealing gaskets, support brackets, insulation sleeves, and chimney caps can further protect your installation and extend its lifetime. These accessories are designed to integrate flawlessly with your MI-FLEX system, ensuring that every component works together harmoniously. Not only do these optional accessories contribute to enhanced performance, but they can also simplify future maintenance and ensure that the system remains compliant with all regulatory standards.
Maintenance and Care
Proper maintenance is fundamental for the optimal performance of your chimney system. Regular cleaning prevents the build-up of soot and debris, thereby maintaining efficiency and reducing the risk of fire hazards. Always opt for non-chemical cleaning methods to safeguard the stainless steel finish of the joiner. It is advisable to have your system professionally inspected periodically, especially if you are utilising solid fuels, to catch and address any potential issues early on.
Addressing Common Concerns
Potential buyers often ask about the need for supplemental accessories and whether the joiner is compatible with different flue liners. Rest assured, the Screw-FIX Joiner is engineered for compatibility with both MI-FLEX 316 and 904 systems, ensuring a reliable fit regardless of the fuel type used. Should you require enhanced system performance, the optional accessories available are highly recommended. They not only bolster the effectiveness of the joiner but also contribute to the overall safety and longevity of the chimney system.

Its robust construction, ease of installation, and adherence to regulatory standards make it an indispensable component for anyone serious about safety and efficiency. Additionally, exploring the range of optional accessories available can further elevate the performance of your entire chimney system, ultimately leading to reduced maintenance hassles and improved long-term reliability.
