hello, yes , but only 2pcs PC4-01 push fittings can fit Mizar S.
other 2pcs are for printers like A10M A10T/A20M A20T/ A30M A30T. and another 2pcs are for single extruder printer like A10 A20 A30PRO.
If you need 6pcs push fittings for Mizar S , you can write a comment for your order, need 6pcs push fittings for Mizar S printer instead
