This O-ring seals the joint on the Triton C-3 Sand Filter. A degraded or compressed O-ring at this location allows water to bypass the seal, resulting in leaks at the filter head connection. Replacing both O-rings at the same service interval restores a proper pressure-tight seal and prevents water loss at the filter.

Pro Tip

Always replace both O-rings as a matched pair even if only one shows visible damage. O-rings at this location are subject to the same age, heat cycling, and compression fatigue, so replacing only one often leads to a repeat leak within a short period. Before installation, apply a thin, even coat of Pentair R172351 Lifeguard Silicone Lubricant to each O-ring to help it seat evenly and prevent tearing during assembly. Never use petroleum-based lubricants they will degrade rubber O-rings and cause premature failure.
