Single O-ring for Big Blue filter housings (using 4.5 inch diameter filters) to replace cracked or torn o-rings that would allow water to leak
Some filter housings use a single O-ring and others use two O-rings. If your housing requires two O-rings, you will need to order two O-rings per housing.
It is recommended to inspect the o-rings change with each filter change if notice any wear, to ensure that your housings are completely sealing to prevent costly and messy water leaks.
