From public catalog excerpts, key parameters include:
– **Reducer Codes**: PR series (e.g. PR18/3, PR18/4, PR24/4, etc.) with combinations of larger DN to smaller DN
– **Example Dimensions**: PR18/3 = transition of DN 450 to DN 80 over a length of 375 (units)
– **Consistency in Series**: For example, PR18/12 is 450 → 300 over 375, PR24/4 is 600 → 100 over 400, etc.
– **Material**: Borosilicate glass construction for wetted surfaces
– **Vacuum / Pressure Compatibility**: Functionally similar to other pipeline parts in the system
– **Design flexibility**: Variants for custom transitions likely available on request
