Made from high quality 304 grade stainless mesh and PTFE teflon.  The bead on this has been design to fit any standard 4 inch tri-clover fitting.

4 Inch Tri-Clover Stainless Mesh Screen PTFE (Teflon & 7 mesh)

This is compatible with all the other 4 inch Tri-Clover fittings that we sell. Like Kegementers or Any 4" column stills.

This Stainless Mesh Screen has a PTFE (Teflon) seal integrated around the outside of it.  The hard PTFE compount is highly chemical and heat resistant.  This can be used as a standard seal or alternatively, it can be used as a filter screen preventing the flow of large particulates going through your tri-clover fittings.

This fitting is often used for distillation to retain packing medial or used in pot distillation to retain botanicals in the vapour stream
