The Omnipure Q5672 Q-Series 50 GPD Membrane with check valve and flow restrictor will fit Omnipure Twist Tap filter heads QNVH B, C, or J with or without automatic shutoff. It is also known as part numbers TQ56-50FC, TQ56S-50, and can be used as a replacement in the Rayne Pure Blue Systems.
The Q5672 with check valve and flow restrictor is the same as the Rayne of Houston (now Raine Systems) Pure Blue Reverse Osmosis System cartridge TQ56-50FC-60 except the thread size is different. To be able to use the Q5672 as a more economical replacement you would simply need to purchase an Omnipure standard valve head. Nothing else needs to be changed. You will keep your existing RO Faucet, cold water feed line valve, drain clamp and storage tank.
Changing this RO membrane and valve head will in no way affect the performance of your system--it will just save you money!
The Q5672 S 50 GPD TFC Membrane can also fit some RO systems by Farris, TGI, ARS, IWW, and the PuROTwist system by Omnipure. Needs to be replaced every 2 years depending on water quality and usage.
