This connector is specifically made in order to modify a Parker 61 pen that originally used the capillary filling system to a converter or cartridge filling system.
They are made out of brass to ensure a strong and durable modification.
The threads on both ends are 0.8mm pitch single start and the bore is 7.5mm to accept the larger size cartridge.
For the conversion a piercing tube is required which is a press fit in the nib end of the connector and fits flush in the recess as can be seen in the photographs.
Please note a new piercing tube is included in the price.
The other modification requires that the barrel has to be modified to accept the larger diameter and length of the cartridge or converter
