The DEX2400K o-ring is the large tank/body seal that sits between the filter’s top and bottom halves. Over time, constant compression can wear the gasket. When you notice leaks at the seam, replacing the o-ring can restore a tight seal and help the filter return to peak performance.

Installation is straightforward for most filter setups. If you’re replacing the o-ring after a leak or maintenance check, the DEX2400K offers a trusted path to reestablishing a reliable seal.

Keep a spare on hand as part of routine upkeep to minimize downtime and keep your filter working as intended.
