What adapter is needed for refrigerator filtration?

I used this for an under sink install and didn’t need anything extra. Im sure this could be used as a stand alone filter on the fridge. I purchased this item AQUACREST GXRTDR Inline Water Filter, Compatible with GE GXRTDR, Samsung DA29-1010... https://www.amazon.com/dp/B0787WGNPS/ref=cm_sw_r_sms_c_api_i_XnM4EbVJ49M0W for my fridge ice maker. I cut the existing water line and installed into each end. Hope this helps.

Why dont you sell a replacement without the hose!?

I think you can buy just the filter without the hose.

With RV sanitation, is there a way to remove the filter and connect the 2 quick connect ends together? or is there an adapter?

Not sure what your wanting to do but, I live full time in an RV now and I have learned that there is always a way and a connector for any thing.
