Mounting Techniques for O-ring Flush Pressure Sensors

[beh188]

I am interested in using an o-ring flush mount pressure sensor such as one of the items shown in the link below:

Does anyone have a description or example of how they accomplished this mounting?


Thanks.

Not sure if these are what you are referring to (web site link was dysfunctional), but when mounted the pressure sensing diaphragm is flush at the bottom of the adapter and the pressure seal is accomplished with an o-ring; the threads are straight threads, not tapered.

I've seen the units the op linked to mounted with snap rings. The data sheet is lacking enough dimensional detail to adequately size the mating port; either a better drawing or an actual unit would be required to get the fit required to ensure the oring will seal.
