Peterson System Stems

Just passing the message around so no one ends up buying a stem that wont fit.
Peterson have changed the stem sizes and (slightly) the bowl shapes of the “Standard System Range. We only found out a week ago, i was told me when i ordered that the sizes had changed and the new stems only fit pipes 3-4 months old. I ordered some anyway and they are not compatible with older models.

As far as i know we can send them back to the supplier for a new stem. Not sure how long this takes, sending my first 2 off tomorrow.Will let you all know how long it takes. I am hoping this is quicker than sending to Peterson direct (which is another option).
