Custom-made M21.5 transition to M22

Extra long adapter M21.5x1 AG to M22x1 AG (approx. 23 mm total length) with an external thread M21.5 (aerator thread) and an external thread M22 (aerator thread): chrome-plated brass

The M21.5 thread fits into a faucet / basin tap, e.g. Hansanova Style, in which a pearl jet
is/was screwed in.

The lower part with the M22 external thread can then be screwed into the AquaDea Vortex, Vita Vortex or Herba Vortex or onto the connector (switch) of the over-sink filter.

This extra long adapter is sometimes necessary for taps in which the aerator thread is located deeper.

• M22x1A x M21.5x1AG,
• chrome-plated brass
• Data: approx. 23 mm total length
• It can also be used as a double nipple M22xM22 AG

To determine whether you have an M22 thread, you can measure the outer diameter of the thread with a ruler. If it reads approximately 22 mm, then it's an M22 thread. If it's approximately 21.50 mm, it's an M21.5 thread. There are also M24, M18, and M16 fine threads on kitchen faucets; newer and designer faucets, in particular, are equipped with the more exotic aerators.

M20 is a rather rare bead-blasted thread. Please measure carefully.
