The PuROTwist PT4000T50-RK (and similar PT4000T75-RK) retrofit kits are specifically designed to work with Culligan® Aqua-Cleer RO systems, particularly those installed between 2008 and 2020 with 1/4" and 3/8" Tubing.
If you have a Culligan® AC-50 or LC-50 Aqua Cleer system, this kit provides a direct conversion for your existing setup. Why replace an entire RO Unit when the tank, faucet and lines are all still good? This high quality conversion kit includes just the manifold and filters. You can keep your tank, faucet and lines installed in place.
Simply remove your old system and plug the lines into this new system. When it is time to service your new system, simply twist the used filters off and twist the new Omnipure Q-Series filters on, at nearly half the price of your proprietary filters! No tools, no buckets, and no mess.
RO Filter Manifold and Water Filters Assembly Only, No Tank, Faucet or Installation Supplies Included.
