COMPATIBILITY & APPLICATIONS
What This O-Ring Fits
This silicone O-ring is engineered for Pentek, Ametek, and Plymouth Products Slim Line filter housings in 5-inch, 10-inch, and 20-inch sizes. It fits housings with cap ports ranging from 1/4 inch to 1/2 inch and a 6-rib internal design. The 3-1/2 inch diameter provides a precise seal between the housing body and cap, preventing leaks and maintaining system pressure. Silicone construction offers superior resistance to temperature extremes and chemical exposure compared to standard Buna-N rubber O-rings, making it ideal for challenging water conditions or installations subject to heat.
💧 Replace your housing O-ring every 2–3 filter changes or whenever you notice stiffness, cracking, or deformation. A degraded seal is the most common cause of housing leaks and can compromise filtration performance by allowing unfiltered water to bypass the cartridge.
