Allows for pipe size to be increased in diameter

John Guest enlarger is a push-fit fitting for blown fibre protected applications that is used to enlarge a microduct pipe size to a wider gauge and provides seamless performance under tough conditions.

Its black body provides added UV protection for the microduct pipe. Featuring a collet with stainless steel teeth, the push-fit fitting provides a secure microduct connection with a simple and instant push-fit action. It eliminates the need for any tools, making the installation process efficiently straight forward. The single O-Ring forms an airtight seal that further enhances the strength of the connection.

In the event of repair or network expansion works, the John Guest enlarger connector provides superior installation flexibility, as the demountable feature of the solution allows for the system to be reconfigured without damage to the microduct or push-fit fitting. John Guest fittings are manufactured and assembled in the UK.
