6" In line GAC post filter S7206W-JG Used on newer Microline Models T.F.C.-4, and -435 NOTE: This cartridge filter has a 3/8" tube connection built into the cartridge at each end for quick and easy connection to a 3/8" tube running to your faucet, but you would not order for older models that have the 1/4" tubing running to the faucet ( order S7206W instead ).
* NOTE: Filters have 1/4" tube stoppers that must be removed before you can use and install your 3/8" tubing. Simply push outer ring in toward filter body, and pull out the center piece of tubing ( stopper ) to reveal the 3/8" opening. You will then insert your tubing into the filter to lock in place.
