With this adaptor the use of G1/4" fitting on the Ehim 1046 outlet is possible. The adaptor can simply be screwed  in replacing the original stout of the pump (1/8" to 1/4" adaptor)

long & short:
Depending on which version is used this adaptor can be more handy to use with large fittings or smaller fittings / tubing sizes. But for both versions please always make sure not to overtighten the adaptor, screw it in only hand-tight under any circumstances to prevent damage to your pump!

Please note: Do not insert the adaptor ''dry'' as the O-ring twists when inserted dry and may not provide a safe seal. Therefore please moisten the O-ring before inserting the adaptor to prevent any problems.

Important: Over-tightening of this adaptor may result in breaking of the plastic shell. As soon as the O-ring has contact and the adaptor is lightly hand-tightened the seal is established!
