I recently ordered the entire filter cannister assembly without the niche, thinking I can re-use my old one. I learned that I could not because the retaining ring was stuck, frozen, fused to the threads. To remove it would destroy it. With the new replacement. All re-installation efforts were accomplished quickly and hassle free.
