Secure Adjust System ©
The original OSKAR SAS-TEC© system
The Secure Adjust System (SAS-TEC) connection technology is as simple as it is ingenious: when the components are joined, a slight turn to the left locks them firmly together. Locking bands secure the connections further for maximum support.
Often copied, never matched. Our Secure Adjust System makes installation effortless and ensures maximum leak-tightness – quality you can trust.

The benefits of the SAS-TEC system
Easy assembly for everyone – the OSKAR SAS-TEC system. Simply twist and secure with the locking band for maximum leak-tightness and durability.

Assembling an OSKAR chimney is child's play. First, the components slot precisely into one another. Thanks to the clever design, every part immediately fits into the correct position. This makes the first step effortless, even without any previous experience.
