The SERTO principle

The SERTO principle

SERTO’s radial system is unique. With SERTO, the cone is in the nut, and not in the body as with other tube unions. Tube unions are incredibly simple to assemble and disassemble.


SERTO components can be connected to each other like in a modular system kit. The unions in the standard range are combined with connecting parts. This creates countless individual solutions that are metallically tight, very compact and available for immediate delivery.
