Bi-Directional is Now Standard with all MKIII and MKIVc Terpenators! April 07 2017

This year we have adjusted our original bi-directional modification components as well as our hoses and fittings to allow for a modular modification kit that can be added to the MK3 and MK4c as simply as you would connect two hoses to the extractor. The modification does NOT require you to use any PTFE tape or make any uncertain NPT pipe thread connections.

This modification comes standard with all MK3 and MK4c Terpenators.
