I just saw this topic and would like to comment.
I repost what Mike Leverette said:
For the Peterson System pipes to work properly, the stem/tenon has to have an extension, the tip of which will pass by the draft hole from the bowl and into the sump. Upon the smoker drawing in smoke, this extension then directs the smoke down and around the sump to dispense a lot of the moisture before the smoke enters the extension and stem. On the System Standards and other less expensive systems, this extension with be made of vulcanite turned integrally with the stem. On the more expensive System pipes this extension will be made of metal which screws into the vulcanite stem. This extension on the earlier pipes will be of brass and the newer pipes will be of aluminum. Most smokers not knowing this function of the metal extension, assumes that it is a condenser/stinger and will remove it as they do with the metal condensers of Kaywoodie, etc. Should you have a System pipe with this metal extension, please do not remove it for it will make the System function properly and give you dryer smoke.
It is sad to say but I have two brand new Peterson Systems which came from the factory without the extension. So quality control is lacking to a certain degree.
Another feature of the Peterson System pipe that helps in removing moisture is the stem itself. It will have a relatively small draft hole entrance at the extension which will open out rapidly and then closes back down near the bit. Of course these varying diameters have smooth transitions. The idea behind this is; the smoke leaving the smaller diameter and entering the larger diameter will expand and slow down, thus dropping more moisture before entering your mouth.
