COMPATIBILITY & APPLICATIONS

Where This O-Ring Works

The Pentek 151117 Viton o-ring is designed specifically for Pentair's natural polypropylene filter housings in 10", 12", and 20" sizes. Viton material makes this o-ring ideal for installations handling chlorinated water, petroleum products, aggressive chemicals, or elevated temperatures where standard Buna-N o-rings would degrade. Common applications include commercial water filtration, industrial process water, food and beverage production, and residential whole-house systems in high-temperature or chemical-exposure environments. Always apply food-grade silicone grease to the o-ring before installation to ensure proper sealing and extend service life.

💧 Replace your housing o-ring every 2-3 filter changes or annually, whichever comes first. A dried or cracked o-ring is the most common cause of housing leaks, and keeping a spare on hand prevents emergency shutdowns.
