Simrell Collection Condenser Tube These Simrell Collection condenser tubes are made from high quality stainless steel and will fit Simrell Collection's Stinger mouthpiece as well as their spinning mouthpiece. These condensers also fit the Simrell Collection 14mm WPA. XL Condenser The Simrell XL condenser fits the larger XL sized MVS. This size condenser is also suitable for Dynavap's larger sized stems of approximately 62mm such as the OMNI, VONG and M range of vaporizers. Just keep in mind that these condensers are not compatible with Dynavap's mouthpieces. You will need a Simrell Collection mouthpiece or WPA. Standard Condenser The Simrell standard condenser will fit the MVS where a mine valve is being used. This condenser will also work with some older dynavap stems like the NonaVong S. If wanting to use with with a Dynavap stem just make sure the stem is approximately 45mm. And again, this condenser needs to be used with a Simrell Collection mouthpiece of WPA.
