- PVDF (-1)
- PFA 440/445 Resin (-3)
- PFA 440/445 Resin with Carbon fill (-6)
- PFA 440/445 Resin with locking ring (-11)
- PFA 940 HP PFA body material with PVDF nut (-1X)
- PFA 940 HP PFA body material with PFA 440/445 nut (-3X)
Guidelines for use:
- PVDF (-1) can be used for all applications with the exception of NH3, NH4OH, TMAH, Developer, and organic solvents. This is the standard nut supplied by Entegris.
- PFA 440/445 (-3) can be used in all applications except specific fluorinated surfactants and high temp/high vibration applications
- Carbon fill PFA440/445 (-6) has a higher tensile strength than a (-3) and can be used in all applications except specific fluorinated surfactants and high temp/ high vibration applications.
- PFA 440/445 Resin with locking ring (-II) can be used in all applications except specific fluorinated surfactants. This nut was designed specifically for high temperature/ high vibration applications. This requires the use of a flarelock II groove tool on the PFA flare.
- PFA 940 HP PFA body material with PVDF nut (-1X) was designed for use with fluorinated surfactants except when blended with TMAH, NH4OH, and other Developer applications. This only applies to Spacesaver fittings. This fitting has a MOQ of 10.
- PFA 940 HP body material with PFA nut (-3X) was designed for use with specific fluorinated surfactants and is the most chemically inert of the Flaretek fitting line. This only applies to Spacesaver fittings. This fitting option has a MOQ of 10.
- -1X and -3X are not common fittings and should not be quoted unless necessary for chemical compatibility or in order to fill an order due to lead times.
*PVDF should always be ordered unless there are specific issues the customer needs addressed i.e. chemical compatibility, lead time, temp/vibration.
+(-3) should be used in all applications except when specific fluorinated surfactants
**(-1X) can be substituted for -1, -3 with exceptions listed above
++ (-3X) can be substituted for -1, -3, -1X
