The EuroSW1 Male to Male Adaptor - Ø 125mm is an essential connecting component for your flue system. Crafted from zero carbon steel, it is suitable for gas, oil, and solid fuel appliances operating at temperatures up to 600°C. Ideal for use as a connecting pipe, the EuroSW1 is designed for easy installation and long-lasting performance.

Ensure the smaller diameter is always pointing downward to keep condensates within the system. Do not use this adaptor to pass through ceilings or combustible walls. While EuroSW1 features a friction fit joint, an optional fire cement or high temperature silicone sealant can be applied for extra security.

Regular maintenance, including sweeping at least once a year for solid fuel appliances, is recommended to ensure optimal performance.

The adaptor is suitable for gas, oil, and solid fuel appliances with operating temperatures up to 600°C.

No, the adaptor should not be used to pass through ceilings or combustible walls.

Ensure the smaller diameter is pointing downward to keep condensates within the system. Maintain a distance of at least 375mm from any combustible material during installation.

While the EuroSW1 uses a friction fit joint that does not require sealing, you can opt to use a jointing compound like fire cement or high temperature silicone sealant for extra security.

Regular maintenance and inspection are advised, especially for solid fuel applications. A chimney sweep should be conducted at least once a year.

Yes, the EuroSW1 can be cut to fit, but any exposed steel should be treated with high temperature paint to prevent rust.

Wearing appropriate personal protective equipment (PPE) and following all installation guidelines is essential for safety.
