High-quality Material: The cartridge motor head sealing O-ring is made of high-quality rubber material, which is durable and has good wear and corrosion resistance, and is not easy to age and oxidize.
Easy Installation: Rubber gaskets will deteriorate over time and are recommended to be replaced once a year. Just remove the cartridge, remove the old gasket and replace it with a new one. When installing, clean the oil filling port and tighten it so that it works properly and no longer leaks.
Leak-proof Design: The O-ring is compatible with canister filters, and the aquarium filter O-ring is leak-proof as a replacement gasket for canister filters.
