Transition Couplers | MicroDuct Connections | Tool-Free
Durable Transition Couplers for MicroDuct Connections — Product Overview
MicroTechnology Transition Couplers are designed to securely join two MicroDucts of different diameters, providing a reliable transition between duct sizes in air-blown fiber optic installations. Their low-profile design and easy push-fit assembly allow for quick installation and disassembly without tools.
These couplers create an air- and water-tight connection while maintaining a smooth interior transition to help protect and support efficient cable and fiber installation. Color coding makes it easy to identify the appropriate coupler size, while the durable construction is designed to withstand chemical exposure and harsh environmental conditions.
MicroTechnology Transition Couplers are tested to meet or exceed the stringent requirements of CENELEC EN 50411-2-8:2009 for MicroDuct connectors used with air-blown optical fibers and are approved for applications up to 232 PSI / 16 Bar.
