Pressure Fitting from Thunder Tiger

Pressure fitting, 1 per package. Replacement part for FS-91. Can be used in any muffler with same thread. In checking threads, this seems to be a 3mm but won't thread into standard 3mm threads. Might some some sort of odd metric pitch. This could be metric 3mm fine thread which is .35mm. Standard 3mm fasteners are .5mm pitch.
SKU Number: TTRPN0131
