As of today 2-step adaptors

As of today we can offer you ATEX-certified 2-step enlargers in brass.

Reducers or reduction rings have long existed in several steps. However, up to now we did not have an adequate solution for enlarging by 2 steps, for example from M20 to M32.
Screwing two adaptors into one another is (still) not allowed and a 2-step adaptor hadn´t been produced, since the design makes it difficult to satisfy the impact test.
Our supplier has now succeeded in developing a 2-step adaptor that meets the new ATEX directive and all the related applicable standards.
