TruTech Tools KTF032 Filter Drier Kit - Pack of 10 (Size 032 Parker Filters and 12" CPS Adapter Hose)

Inline filters should always be used to ensure that no solids or particulate matter gets into the recovery machine. Every system that refrigerant is recovered from has a liquid line filter dryer in it ahead of the expansion device. It performs two important functions: trapping and collecting ant large particles (copper shavings, solder, flux, wax, dirt, scale, etc.) that might be in the system; capturing any moisture that might enter the system due to leaks.
