Tech/Engineering - Engineering: Industrial / Pneumatic
German term or phrase: Schliff
Der Ventiltyp VACUUM erzeugt an den Übergabepositionen zwischen FU und DAU ein Vakuum, da an diesen Positionen durch den Schliff kein Haltekreisvakuum anliegt.

In diesem Kontext ist mir den Begriff Schliff unbekannt.

ground joint / ground glass joint


Explanation:
Es handelt sich um eine geschliffene Verbindung, wobei die beiden Teile so geschliffen sind, dass sie genau ineinander passen. Standardausdruck in der Chemie.
Ist auch bei Wikipedia abgebildet.

Or, alternatively: ground glass connector (not so frequent)

neutral  Richard Stephen: They are obviously not talking about glass here, nor is a "joint" present.

neutral  D. I. Verrelli: In general these seem to be good options. Based on information in hand, the material _may_ indeed be glass.

(ground) shape, pattern, form


Explanation:
In order to hold a vacuum, the parts would have to be ground (geschliffen) to match one another exactly. This is not the case, the "Schliff" is not adequate to hold a vacuum.

cut


Explanation:
I would use the word cut here to make it plain what the context is all about.

finish of the surface


Explanation:
Total stab in the dark but I thought I put an idea in.
Although "Schliff" is usually associated with the way a cutting instrument is leaving a surface, I could imagine that the method of how the surface got that way is secondary here...

Socket / Port


Explanation:
A valve can't create a vacuum; however, it could maintain a vacuum. This might be necessary if there's no convenient connection to a vacuum line — as seems to be the case here. I can't find any use of "Haltekreisvakuum" anywhere, but I assume it refers to the house vacuum system. (See https://www.labcompare.com/10-Featured-Articles/116935-Labor... )

Now, the house vacuum would only have an effect if there were a 'portal' at which it could be connected. That must be the "Schliff".
https://de.wikipedia.org/wiki/Normschliff
https://www.vdg-ev.org/fileadmin/media/vdgn/2014/oeldiffusio...

I agree that "joint" is worth considering, as per Barbara Schmidt's proposal.
https://www.sigmaaldrich.com/catalog/product/aldrich/z530662...

To me a joint suggests that both sides of the connection are present. In this instance only one side of the potential connection is present (because house vacuum is absent), and for that reason I want to propose some alternatives.

Firstly "socket", which is compatible with description of ground-glass joints.
https://www.bing.com/images/search?q=+laboratory glassware s... https://www.sigmaaldrich.com/catalog/product/aldrich/z309052...

Secondly "port", as a common term describing openings on labware (but not usually for ground-glass joints).
E.g. https://www.sartoriusglobal.com/mediafile/Broch_UniVessel_SU...
https://www.bing.com/images/search?q=+laboratory glassware p...

Now I don't know whether the material is glass or not, nor whether it is indeed ground. The word "Schliff" does imply that it is ground — unless the word has been used loosely. Perhaps more important would be what is most relevant functionally about the thing that this word is trying to describe, and to me that appears to be the fact that a connection can be made there.

Other options:
* "neck" (but I think this doesn't focus on the most relevant functionality); https://www.sigmaaldrich.com/catalog/product/aldrich/z555584... https://www.sigmaaldrich.com/labware/labware-products.html?T...
* "connector" (although it might be assumed to refer to short linkages);
* and in various other contexts "nozzle", "branch", etc..

With more context about the application a more conclusive suggestion can be made.

If the detail remains unclear, you could also resort to something very generic, like "opening".
