About this product

Keep your aquarium filtration system running flawlessly and protect your floors from costly leaks with the genuine Oase BioMaster Main Gasket (Part Number: 45148). Over time, exposure to water pressure, debris, and routine maintenance can cause your filter's original seal to stretch, flatten, or degrade. Replacing this main gasket during your regular filter servicing is the easiest way to guarantee a secure, airtight, and completely watertight lock on your equipment. This high-quality replacement seal is manufactured from premium, high-density black rubber, offering superior compression recovery and resistance to stretching. It is precisely molded to slot directly into the sealing groove around the main pump head, forming a highly reliable barrier where the motor head meets the canister body. Maintaining a fresh gasket ensures your filter operates with maximum suction and water-turnover efficiency.
