The De Marinis DESIGN SDMA female-female sleeve is a component of the DESIGN flue system mainly used to reverse the connection direction between flue components for wood-burning stoves, fireplaces and biomass appliances.
The component features an anti-condensation separator ring and is particularly useful where two male ends need to be connected within the flue system.
It is manufactured from 2 mm carbon steel with a matt black high-temperature finish. Its robust construction and clean appearance make the DESIGN range suitable for visible indoor installations.
The SDMA sleeve is available in nominal diameters Ø 120, 130, 140, 150, 160, 180 and 200 mm, with a constant overall height of H = 120 mm.
The SDMA sleeve is used where the direction of the flue system joints needs to be reversed.
Its female-female configuration allows two components presenting male ends at the connection point to be joined correctly.
This component is commonly used at the base of the flue system or in specific installation layouts where the direction of the joints must be changed.
Before purchasing, select the correct diameter and check compatibility with the other DESIGN components in the installation.
The SDMA sleeve features an anti-condensation separator ring designed to provide the correct connection geometry where the direction of the joints is reversed.
Correct joint orientation is important in a flue system and must comply with the manufacturer's installation instructions and the technical configuration of the system.
Important: the SDMA should not be treated as a generic universal connector. The need to reverse the joint direction and the correct position of the component must be determined according to the flue system configuration and De Marinis installation requirements.
The SDMA belongs to the De Marinis DESIGN system manufactured in accordance with EN 1856-2:2009 for metal flue systems and connecting flues used with biomass appliances.

Technical note: the SDMA sleeve is available in nominal diameters from Ø120 to Ø200 mm and has an overall height H of 120 mm for every variant. It features a female-female configuration and an anti-condensation separator ring. Please also refer to the technical drawing included on the product page.
Comparing the technical drawing, dimensional table and selected diameter helps identify the exact De Marinis product code required for the installation.
For correct dimensional continuity and system configuration, the use of De Marinis components from the same range and with the same nominal diameter is recommended.
Before combining components from different systems or manufacturers, their dimensional, technical and regulatory compatibility must be checked.
Diameter, sleeve position and joint direction must be determined according to the overall configuration of the connecting flue.
The DESIGN system is intended for indoor installation. Installation must be carried out by qualified personnel in accordance with the appliance manufacturer's instructions, De Marinis system requirements and applicable technical regulations.
