Important Note about Jacuzzi compatibility: This part is an exact replacement for the Waterway 805-0448 and Pentair/StaRite WC9-3 o-ring. It is slightly smaller in diameter and slightly thicker than the original Jacuzzi 78105 o-ring. However, since the 78105 o-ring is discontinued, this is the part we recommend J-C150 owners to order as it has been tested and confirmed to seal these filters as a way to still offer a replacement to the discontinued part.
