DI Buttress 4.5″ O-Ring | 10436

The 10436 DI Buttress 4.5″ O-Ring is a replacement sealing gasket used on 4.5″ DI buttress-style filter housings. Over time, housing O-rings can flatten, crack, or swell—leading to seepage, pressure loss, and recurring service calls. This O-ring is intended as a dependable replacement to help maintain a leak-free seal and consistent system performance.

Ideal for routine maintenance, rebuilding kits, and service technicians, this housing seal supports clean reassembly after filter changes and helps reduce downtime caused by worn gaskets. For best results, inspect the groove and sealing surfaces, clean debris, and lubricate with a compatible O-ring lubricant before reinstalling.
