PF3W7-X365 is an application specific version of the standard PF3W7 with SUS316 stainless steel compression fittings in place of the threaded pipe adapters. Further refinements include EPDM seals, as well as double O-rings when the optional flow adjustment valve is selected. These upgrades allow for the measurement of the flow of fluorinated liquids such as Fluorinert™ or GALDEN
