Frequently asked questions

Difference from losflansch?

Festflansch sits fixed in one orientation. Losflansch (5611) is a loose flange that can rotate freely around the pipe end - helpful when the bolt pattern must be aligned with an existing mating flange.

Compatible with CONNECT 244?

Festflansch can be used as mating flange to CONNECT 244 (loose flange per DIN 2632/2633). Cross-check bolt circle and dimension.
