Micro duct reducers  are high quality push to fit fittings designed to offer the highest of performance for blown fiberoptical fibre installations. Primary use of the fittings is for joining unequal diameter micro duct in a range of industry standard sizes，The reducer design incorporates a different size cassette type collect at either end made from engineering thermoplastic. Characteristics of this POM, material are high stiffness and low friction for positive duct insertion and disassembly. The excellent dimensional stability of POM ensures consistent performance in a range of environmental conditions. The Mikrodukt microduct connectors are tested to the industry standard of EN 50411-2-8:2009.
