Product Description

The O-Ring for the Sun Sun HW-304B canister filter provides a secure, watertight seal between the canister body and the filter head. Over time, O-Rings can wear out, flatten, or crack, causing leaks or reduced filter performance. Replacing the O-Ring restores a proper seal and helps your filter run smoothly and reliably. This O-Ring is made specifically for the HW-304B model for an accurate fit.
