Would it fit on the steam tip to steam wand thread ... It's the only gasket in the vicinity ?

 

Tadaa! It would appear there are more than one seal around after all?

 

This little red ring actually fits onto the teflon tube part to stop it leaking and heating up the steel outer part of the wand. It never worked well, usually ends up in the tip once the tip is removed for cleaning and often fractures. There is one at the top and bottom of the wand....but really about as useful as peeing on a house fire. it's why no burn wands are not quite as "no burn" after a few weeks/months.

You can happily discard it.

P.S. It's in almost all no burn wands, not just Duetto ones.

 

Ah! Thank you. I understand some people discard the whole Teflon tube? But I'm not sure why?

Well it's the whole no burn thing...sorta depends on the machine.

1. No burn wands do get hot when used for a while either one long steam on a lower powered machine, or 2 steams on a fast steaming machine

2. On a machine with plenty of steam power a no burn wand can restrict and slow down steaming, faster steaming gives sweeter milk and better texture

So really no burn wands should have the same cool grip bits as "burn" wands..but to save a few pence, manufacturers usually don't fit them...I think I specified that they do fit them on the Verona steam and HW wands. If they don't and you remove the inner teflon tube, you need to fit some.

If you have the later model Duettos where the service boiler shares the PID loop with the brew boiler, then it's steaming power is reduced from what it could be (as it is in ANY DB machine that doesn't have a separate PID loop for the service boiler). So removal of the teflon tube, may require changing the steam tip to one with smaller holes. Conversely removing one, could require steam tip hole size is increased (less likely) on machines able to supply more powerful steam

So really it's a try it and see what you prefer scenario, but for your machine, I don't think it will make a huge difference.

P.S the wand shaft is easier to clean when it's "no burn", even on a "burn" wand, the shaft is easy enough to clean, but the tip is no easier to clean and it's usually the tip where the problems come.

 

A lot of "know" around this forum. Thanks Dave for sharing your wisdom. My machine being mk2 I guess I have the old PID setup?

Have offered the three pack of Izzo steam tips. I hope to be able to steam better than before.

The best steamers of the Duettos were the ones that had a PID for the brew boiler and a pressurestat for the service/steam boiler....not sure whether they extended into the MKIIs or not.

 

Ah. I think the pressostat was only in the first generation. The ugly machines with plastic feet and uninsulated steam boiler.
