PlumbShop O-Rings Seal, Rubber, Black, 15/16 x 7/16-in

A reliable seal is key to saving water and energy around the home, and these durable rubber O-rings from PlumbShop deliver. The black rubber construction means they will form a tight seal wherever you need one, whether on plumbing fixtures, valves or pipes. The compact size of 5/16 inch by 7/16 inch makes them ideal for most standard applications. Simply stretch the O-ring over the fitting and watch the leaks disappear. Hassle-free installation and longevity mean you will quickly forget they are even there - except for the money you'll save on your water bill.
