    Hello, in a box I with Primus parts I bought some time ago I found a silent burner with no preheating cup.
    In the same box I found a preheating cup with a piece of pipe attached an it more or less fits the burner.
    Question now is do these parts belong together and if so, on which stove does this burner belong?
    Diameter of the burner is 6.5 cm and the height is 11 cm.

    This is a bit of a head scratcher. It looks like a pre-war model silent burner, but the oval logo hints at the 60's.

    If the short pipe, with primer bowl attached, fits the long riser snugly, the combination then might be the burner assembly for a domestic stove. With this unusual riser soldered directly into the lower U-tube, Primus would save the making of the usual screwed coupling that attaches burner to a riser, clamping the primer bowl in between. The cylindical thread on the bottom would then be screwed into a tank or short coupling. Just thinking 2 pennies worth aloud. Mike

    Primus 4100 burner. In THIS post I said,

    That one of mine is on a Primus 53 but I have another installed on s brass tank discus No.54.

    A roarer version with that mounting pattern was made too. Here on my Primus 51.

    From 1927 catalogue.

    Burner was removed and installed by gripping it in the hand and twisting. The tapered threads made the seal, very effectively I’ve found, without the need for a wrench on hexagon flats.

    John, the screwed connection with those 51 and 53 tanks, isn't that a conical thread? Or am I mistaken about the cilindrical thread I think I saw above? Mike

    Ok, thanks you all, so it certainly belongs together, I have e few tanks in the 50 series mentioned in the advertisement so I will put things together.

    Regards,

    Ton.

    Burning now, on a Primus No 54 from 1926.
    I had a little problem with the NRV, had to remove the whole pump.
    And the thread in the burner is becoming a bit worn, but thanks to the picture of a catalog on this forum I found out Primus once made tapered nozzles to tackle that problem.

    @ton visser Very fine. Good luck finding a taper-threaded jet nipple. It needs to be of 0.23mm orifice too, making it even rarer.

    I found taper threaded nipples at Fogas.se MUNSTYCKE
    Not sure about the size but I can contact them, normally we are in Sweden during the summer, we will see.

    Regards,
