    1. The OR-100 o-ring is perfectly doubled up in the package so the o-ring looks too small for your housing at first glance
    2. Once you take it out of the package, you will see the OR-100 o-ring is the correct size for the Big Blue housings

    The OR-100 o-ring is a lubricated rubber gasket for Big Blue whole house housings. The OR-100 is NOT for Big Clear housings. The OR-100 O-Ring has been branded under Ace Hardware, American Plumber, Ametek, Culligan, Pentek, and USFilter Plymouth Products. The OR-100 o-ring should be replaced every two filter changes or if there is damage to the OR-100 o-ring. The Pentek OR-100 o-ring gasket should be well-lubricated with silicone lubricant to prevent leaks in the water filtration system.
