ordered bunch of those from web shop
https://shop.vems.hu/catalog/sensor-type-p-183.html?osCsid=fb712e163f8c83f15894be13173e522f
which is the default fitting for those sensors? weldable with sensor support or one with 1/8 npt thread?
once ordered I got them with 1/8 npt, other time weld to manifold stuff with sensor support that it could be extented deeper into exhaust.
I need them with 1/8 npt, but would like some aditional ones which can be welded directly, no problem to pay for it.
