Double symettric coupling

Discover our range of Guillemin-type symmetrical double coupling reducers, designed to enable the safe and efficient connection of two different diameters within fluid transfer systems. These symmetrical reducers feature two standardised symmetrical ends, ensuring full compatibility with other couplings in the range. Available in many standard diameter combinations, typically from 20 mm to 100 mm, they are manufactured in aluminium, polypropylene or stainless steel and are compliant with the French standard NF E 29572. These symmetrical double coupling reducers are ideal for industrial, agricultural, logistics, chemical and food-grade applications, providing a reliable solution to adapt pipe or hose sizes while ensuring a quick and leak-tight connection.
