- A cheap part that stops a leak A hardened or flattened o-ring is the usual cause of a weep at a filter joint.

Product details
The Sta-Rite 35505-7438 is a replacement o-ring for the System 3 modular DE filter, covering models S7D75 and S8D110.
Which o-ring is it
The source data is not consistent about the position. The listing name calls it the System 3 elbow o-ring, while the product record for the same part number calls it a tank o-ring. The part number itself, 35505-7438, is the reliable detail, so check it against the parts diagram for your filter before ordering rather than going by the name alone.
When to replace it
O-rings harden, flatten and take a set with age and heat, and that is the usual reason a filter starts to weep at a joint. Any time that joint is opened, fitting a new o-ring is cheaper than going back a second time.
Fitting
Clean the groove and the mating face before the new ring goes in, and use a pool grade silicone lubricant. Petroleum based grease swells rubber and ruins an o-ring quickly.
