Kest-Lock Tank Flange

Kest-Lock Weld-in Flange for Tanks

The kest-lock tank flange is ideal when you want to have a kest-lock connection on your tank. You weld the tankflange in your tank and attach the kest-lock connection on it, by using either the kest-lock basic ring or the kest-lock snap ring.

The kest-lock is designed for critical applications where aseptic design, easy and fast operating are essential, which is why it doesn’t need tools because of the unique quick coupling, it has no lose parts and can be easily operated with one hand.
