The seals arrive with a smooth matte finish and a precise shape that promotes an even, consistent seal around the motor head lid. When installed, they help create a dependable barrier against small leaks, supporting smooth filtration operation. While no seal can guarantee leak-free years, the combination of a snug fit, durable elastomer, and careful installation can contribute to steadier performance and fewer maintenance interruptions.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility and fit\u003c\/h3\u003e\n\u003cp\u003eThese o-rings are listed for Fluval models 304, 305, 306, 307 and 404, 405, 406, 407 canister filters.
