The STORZ reduction coupling is a reliable solution designed for installations transporting liquids and bulk materials, offering versatile use in firefighting, irrigation systems, agriculture, food processing, and the chemical industry. Its symmetrical connection system ensures quick and effortless assembly, while the large, unobstructed flow diameter guarantees efficient transfer of media without unnecessary resistance. Compatible with all elements featuring the same coupling spacing, it provides flexibility and ease of integration into existing systems. Available in two versions, the forged aluminum coupling withstands working pressures up to 16 bar and is equipped with a durable white NBR rubber seal, ensuring maximum strength and safety in demanding conditions. The cast aluminum version, with a working pressure of up to 6 bar and a black NBR rubber seal, offers a cost-effective alternative for less demanding applications. Combining durability, precision, and ease of use, the STORZ reduction coupling is an essential component for professionals seeking efficiency and reliability in fluid and bulk material transfer systems.
