A durable and reliable connection method that saves time and money

The inlet and outlet pipes of liquids, gases and solids can be connected easily, safely, and quickly with Norma collar fittings – even in tight spaces. Thanks to the wide selection of types and sizes, they are suitable for use in both standard and special applications. The German Norma pipe collar fittings are a compact and economical way to connect all metal and plastic pipes with smooth ends. 

With the hand-installed Norma flange connector, reliable connections can be made for pipes of different applications and materials. The Norma collar connector is an effective alternative for connecting plastic and metal pipes in machine, house and shipbuilding, land and water engineering, and hydro engineering.
