“I saved 20% on my purchase compared to other retailers. Exceptional service!” – Jane D.
The Screw-FIX Top Hat Adaptor - Ø 175 is an essential component for constructing a secure and efficient chimney system. Specifically designed for use with MI-FLEX 316 and 904 flexible flue liners, this adaptor ensures a strong, gas-tight seal. Suitable for appliances running up to 600°C, it can handle wood with less than 20% moisture, smokeless coal, gas, and oil.
Regulations require flexible flue liners to be entirely enclosed inside a masonry chimney, ensuring both safety and efficacy. To guarantee a perfect transition from the connecting flue system to the flexible liner, the adaptor must be securely fitted at the base of the chimney below the register plate, offering a clean and professional finish. Regular maintenance and sweeping by a competent person are recommended at least once a year, especially for solid fuel systems.
Follow HETAS guidelines for a safe, long-lasting chimney.

Buyer's Guide to the Screw-FIX Top Hat Adaptor - Ø 175
The Screw-FIX Top Hat Adaptor - Ø 175 is a critical element in ensuring your chimney system operates safely and efficiently. At National Flues, our commitment to quality and safety is reflected in every component we offer. In this guide, we will provide you with a comprehensive understanding of the adaptor, its installation process, and how it integrates with a fully compliant chimney setup.
Product Overview
The Screw-FIX Top Hat Adaptor is engineered to connect MI-FLEX flexible flue liners to a masonry chimney system. It is manufactured from high-grade 316L stainless steel, ensuring durability and resistance against the corrosive effects of heat and combustion by-products. This adaptor is specifically designed for appliances that run on wood, smokeless coal, gas, and oil, and can withstand temperatures of up to 600°C. Its precision design guarantees a secure, gas-tight connection, which is essential for the safe operation of your heating appliance.
Key Features and Their Benefits
Seamless Compatibility:
• The adaptor is designed to work perfectly with MI-FLEX 316 and 904 flue liners. This compatibility simplifies the installation process by ensuring that you have the right component for a robust connection.
Durable Construction:
• Made from 316L stainless steel, the adaptor is built to last. It resists corrosion and degradation caused by high temperatures and harsh weather conditions, which means fewer replacements and long-term savings.
Secure and Gas-Tight Seal:
• The adaptor provides a tight seal that is essential for both safety and efficiency. A gas-tight connection prevents the escape of dangerous fumes and ensures that the appliance operates within safe parameters.
Neat and Professional Finish:
• With a built-in round cover plate, it offers a clean transition from the connecting flue system to the flexible flue liner. This not only enhances the aesthetics but also reduces the risk of installation errors.
Installation and Compliance
Correct installation of the Screw-FIX Top Hat Adaptor is crucial. The adaptor must be fitted at the base of the chimney directly below the register plate. It is imperative that the entire flexible flue liner, and by extension the adaptor, is completely enclosed within a masonry structure. Building regulations strictly prohibit the use of non-masonry enclosures such as timber or plasterboard for this purpose.
Installation Steps:
1. Positioning: Ensure that the adaptor is securely placed beneath the register plate.
2. Sealing: Use a high-temperature sealant—fire cement, ceramic rope, or tape—to secure the connection and maintain a gas-tight seal.
3. Inspection: After installation, have the system inspected and swept by a HETAS registered professional to confirm compliance and safety.
Optional Accessories to Enhance Your System
While the adaptor itself is a vital component, the complete functionality of a chimney system often relies on additional accessories that can optimize performance and safety. Consider exploring:
• Register Plates: For a uniform and professional look that complements the adaptor.
• Sealants and Tapes: To ensure that every joining is secure and gas-tight, reducing the likelihood of leaks.
• Maintenance Kits: These may include brushes and cleaning tools specifically designed for chimney maintenance.
Incorporating these accessories not only enhances the aesthetic appeal of your chimney but also ensures that every connection is secure and compliant with safety standards.
Overcoming Common Objections
We understand that some customers may have reservations about installing new components in their existing chimney systems. Here are a few common objections and our responses:
"I’m concerned about compatibility with my current system."
Rest assured that the Screw-FIX Top Hat Adaptor is designed to work seamlessly with MI-FLEX flexible flue liners, which are widely used in modern chimney systems. Its design promotes a secure fit, reducing any compatibility issues.
"I’m not sure if I need additional accessories."
While the adaptor alone provides the necessary connection, complementary accessories such as register plates and sealants can offer enhanced protection and a more polished finish. Investing in these can prevent future repairs and increase system longevity.
"Installation seems complicated."
The installation process is straightforward when following the provided guidelines. However, should you have any concerns, consulting a HETAS registered professional will ensure that every step is correctly performed, giving you peace of mind regarding safety and compliance.
Maintenance and Ongoing Support
Keeping your chimney system in optimal condition is essential for safety and efficiency. Regular maintenance, at least once a year, ensures that any potential issues are identified before they become serious problems. A HETAS registered sweep should inspect and clean the system after periods of heavy use, especially for solid fuel systems. Additionally, staying informed about the latest accessories and maintenance products from National Flues can further enhance the longevity of your installation.
