Technical details

d = Tube outside diameter L = Installed length e = Minimum bore
Reduction union
The SO 81821 reduction can be screwed onto all SERTO moulded parts with a matching thread and must be tightened with 1/4 turn. This combination enables further tube reductions.

Sealing principle: On assembly, the sealing edge of the transition piece presses into the SERTO moulded part. This produces a perfect metallic seal. We recommend that the thread is secured against accidental unscrewing by means of a suitable liquid adhesive.
