Condenser Set Up 1

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)

One of the best!

If anyone is wondering, this stem mates perfect with a omni mouth peice and condenser. I took a gamble on it and it's easy to say it's in my top 3 stems. Works well with simrell parts as well. Excellent buy!!!!!! Side note- this shop is awesome and shipping is super fast!!!!!! STOKED! THANKS GUYS!!!!!


Love it

Skip the Vong. Grab the assassin.

What can I say? This is the perfect stem/wpa to upgrade an M tip. I love mine and plan on grabbing a second.

Cool and sturdy. It's even better if the air holes are a little smaller.
