In this comprehensive buyers guide, we explore every detail you need to consider, address common concerns, and walk you through the benefits of this essential adaptor.
Overview and Key Benefits
The Screw-FIX Adaptor serves as a crucial link between a rigid single wall flue system and a MI-FLEX flexible flue liner, ensuring a smooth and gas-tight transition. Engineered from high-quality 316L stainless steel, this adaptor not only promises longevity but also performs reliably under extreme temperatures of up to 600°C. Its precision design, which complies with UK Building Regulations Document J as well as CE and HETAS standards, makes it a top choice for both trade professionals and retail customers.
- Durability: The use of 316L stainless steel means your adaptor is resistant to harsh weather and corrosive elements. This ensures that your investment stands the test of time, even in demanding applications.
- Versatility: Compatible with MI-FLEX 316 and 904 flexible liners, it caters to a wide range of fuel types from wood (with less than 20% moisture) to oil, gas, and smokeless coal. This adaptability makes the product an ideal choice in varied scenarios and fuels.
- Safety and Compliance: With a strict adherence to UK regulatory standards, you can install this adaptor with confidence, knowing that it enhances the overall safety of your chimney system.
Technical Excellence
One of the standout features of this adaptor is its robust construction. The 1mm thickness of the 316L stainless steel ensures that the component is both strong and reliable. Additionally, it is designed to facilitate a secure connection between the flue system components when installed with approved accessories such as fire cement or high-temperature sealants. This precise engineering means reduced risk of leaks or failures, contributing to the safety and efficiency of your heating system.
Installation Insights
Installing the Screw-FIX Adaptor is straightforward, but it is critical to follow best practices to ensure an optimal and safe setup:
- Preparation: Before beginning the installation process, ensure that all necessary components and optional accessories (like ceramic rope or high-temperature sealant) are available. Check that your MI-FLEX liner is correctly measured and fully contained within your masonry chimney.
- Application of Sealant: To guarantee a gas-tight seal, carefully apply the sealant around the adaptor junction. This not only fortifies the connection but also safeguards against any potential leakage that might compromise safety.
- Professional Advice: While the adaptor is designed for ease of use, it is always advisable to have a competent professional oversee or conduct the installation. Incorrect installation can lead to issues with flue performance and safety standards.
Addressing Common Concerns

Yes, the Screw-FIX Adaptor is designed for MI-FLEX flexible liners and fits rigid single wall flue systems of 125mm diameter perfectly. Its compatibility with multiple fuel types adds further assurance of its suitability for a variety of heating systems.
What should I do if I lack installation experience?
We strongly recommend engaging a certified professional to handle the installation. Not only does this guarantee compliance with safety regulations, but it also ensures that the adaptor performs at its best. Additionally, using recommended accessories such as fire cement or high-temperature sealants can further simplify the process.
How often should maintenance be carried out?
Regular maintenance is key to prolonging the lifespan of your flue system. For optimum performance, have your chimney inspected at least once a year, or twice a year if you primarily use solid fuels. This routine helps identify potential issues before they escalate into major problems.
