Condenser Set Up 2
For a Completely Closed Off Air Port. This Setting is Perfect For Using with a Water Piece. (See Fig.2)

Intercooler & No Condenser
The Assassin Stem can function with No condenser, or you can place a Simrell Intercooler inside the top of the stem just below the tip. (See Fig.3)

It’ll rest perfectly on a 7mm wall within the stem. (See Fig.4)

If you hold the stem with the airport facing down and cover the airport half way with your thumb, the Intercooler actually spins within the stem creating a cyclone of cool vapor shooting straight into your mouth.

We recommend completely covering the airport with your thumb and feather the airport thus spinning the Intercooler.

See Fig.5 to see the Intercooler will look like within the stem.

An O ring fits snug around the middle Rim of the stem. Here is were you can hold your O ring when not in use. (See Fig.6)

O’ring around the lower middle rim will allow the Stem to function as 14mm WPA (Water Piece Adapter) thus creating an air tight seal. (See Fig.7)

O’ring in Bottom Position was Designed so that the Stem may also be used as a 10mm WPA although you may have to hold it against the Water Piece. (See Fig.8)

Now Enjoy All the Features of the Assassin Stem to the Fullest!!

Joe King Assassin Stem

one of my best purchases, the Assassin stem takes the DynaVap to the next level of smooth and comfort... the feel and weight of the titanium stem just adds to the enjoyment of the smooth taste the stem provides. Without a doubt I'd recommend this purchase, especially here, from VGoodiez, who are a remarkable vendor. They are quick and responsive and if problems arise they are on top of it quickly ..stop reading this and buy one!
