Descriptions:
The thread on the back of the button is a 1/8” BSP Parallel male and seals on the internal cone.
The adaptor is a “-02” (dash 2) ⅛ BSPP male to ⅛ BSPP male (not BSP Taper, which seals by an interference fit between male and female threads). Again the seal is obtained on the internal cones, although new fittings with good straight hex faces will seal on dowty washers if screwed into a port.
As I said before you can check the BSP specs here: https://www.amesweb.info/Screws/British-...-BSPP.aspx
If these fittings are ⅛ BSPP they will measure 9.728 mm across the thread with 28 threads per inch, if 1/4 BSPP
13.157 mm and 19 tpi.
