The rectangular connection has joining profiles of 30 mm flange, and the circular connection has Safe seal.

The rectangular connection is available with offsets as shown in the coded sketches.

Specify dimensions e and h only for alternative 6. Negative values for e, for example, indicate that e is outside side a.

The LORU rectangular-to-round transition is also available with alternative circular connection designs:

LORNP: Transition with male coupling (without gasket)
