Swapping the worn or broken nut and knob assembly prevents leaks and keeps your filtration system serviceable without replacing the entire clamp ring. The part is compact, straightforward to install and intended as a like-for-like spare for older and current filter setups.\u003c\/p\u003e\n\n\u003ch3\u003eWhich filters will this Swimables assembly work with?\u003c\/h3\u003e\n\u003cp\u003eThe R0357500 was made to be compatible with many Jandy and Zodiac filter housings.
