Product details
The Sta-Rite 35505-1429 is an O-ring listed for the System 3 SM cartridge filters, measuring 1-5/8 inches inside diameter with a 1/8 inch cross section.
Fitment
It is listed for the System 3 SM models S7M120, S7M400, S8M150 and S8M500. Because the two dimensions are published, you can measure the ring you are replacing and confirm the match before ordering rather than guessing from a picture.
When to change it
O-rings do not usually fail suddenly. They harden with heat and chemical exposure, take a permanent set in the shape of the groove, and then one day the joint weeps. Renewing them whenever the filter is open costs very little compared with chasing a leak later in the season.
Assembly
Clean the groove, wipe the ring, and use a silicone based O-ring lubricant. Lubricant is not there to help it seal; it is there to let the ring slide into place without being pinched or twisted as the parts come together.
