Rubber seal: 57mm OD, 48mm ID, 3mm thickness. SH80 hardness ensures optimal compressibility for leak-free sealing of water pump components. SH80 hardness provides load-bearing capacity under pump pressure. Reinforced construction prevents deformation when bolts are tightened, and outlasts standard seals. Made of oil-resistant nitrile rubber (NBR), this gasket withstands water, coolants, and mild chemicals. Ideal for long-term immersion in aquatic environments without degradation or cracking. Direct replacement for worn seals in filter pumps, fountain pumps, and pond circulation systems. Restores factory performance by preventing leaks at housing joints and connections. Contains 10 seals for multiple repairs or spares. Quickly replace during pump maintenance, cleaning, or seasonal installations, saving costs and reducing downtime., Manufacturer: SG Store
