Series 0015-2500 with conical clamping hubs

The actual weight is determined by the size of the fitting (D).

Up to series 300 the couplings are glued, from series 500 they are welded.

* = Switching distances generally apply to the middle setting range and may slightly deviate downwards or upwards.
