We have tested the equipment (TFS-15-116 ATFD-H) with 3mm thk and 208mm ID Neoprene O-Rings, and the vacuum test is okay. We confirm that the O-ring specifications sent to you are correct. Please proceed to ordering of EPDM O-rings at your end and ensure that the diameter supplied is matching with our specifications.                                           
We are ready to dispatch the ATFD-H by Saturday, 25th June. We will be sending across the Installation Manual before that.
