This is compatible with all the other 2inch Tri-Clover stuff that we sell.
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 prticulates 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
