Dealing with a leaky Big Blue water filter housing? Chances are, you just need a fresh O-ring! This 5-pack contains high-quality replacement O-ring gasket seals that are designed to be identical in form, fit, and function to the original Pentek 151122 O-ring. Over time, the original rubber seal can become worn, flattened, or cracked, leading to drips and water loss. Replacing it is one of the simplest and most cost-effective maintenance tasks for your water filtration system. These O-rings are made from durable, food-grade compatible materials to ensure a safe, watertight seal for your drinking water. The pack of five is fantastic value – you can replace the seal immediately and have spares on hand for future maintenance or for other filter housings. Installation is a breeze: just turn off the water supply, release pressure, open the filter housing, remove the old O-ring, clean the groove, lubricate the new O-ring with a little food-grade lubricant (like silicone grease), and pop it into place. It's a quick fix that can save you from water damage and ensure your filtration system is working efficiently. A must-have for any homeowner, plumber, or water treatment professional who uses the popular Pentek Big Blue standard-sized housings. Keep your system leak-free!
