Use this DN40 tri-clamp adaptor to fit your T500 reflux condenser to any 2″ tri clamp fitting.

Simply screw into the base of the T500.

Requires a 2" tri-clamp and 2" mesh to hold saddles in place.
Alternatively you could use a 2" gasket and copper or stainless scourer / packing to hold the saddles in place.

Compatible with any 2" tri-clamp fitting like the Still Spirits sight glass or tri-clamp steam lid 

If you plan to use this adaptor with the Alembic condenser then you will need a seat seal. See here
