- Measured size 215 mm by 6 mm, so it can be checked against the ring you have out.

- Also listed with the E91 The source files this ring under both the Model 433 and the Model E91 pump parts, so verify against your pump.

Product details
The Speck 2920341220 is the casing o-ring for the Model 433 pool pump, measuring 215 mm by 6 mm. It is the genuine Speck part.
Where it sits
The casing o-ring seals the split in the pump housing. That joint has to hold on both sides of the impeller, against suction on the way in and pressure on the way out, so a ring that has hardened or taken a set shows up as air pulled into the system or as water weeping from the seam. Neither symptom improves on its own.
Ordering and fitting
Check the measurement, 215 mm by 6 mm, against the ring you have out. The source lists this same part under both the Model 433 and the Model E91 pump breakdowns, so verify the number against your own pump rather than going by model name alone. Clean the groove, dress the new ring with a silicone based lubricant, and draw the casing bolts down evenly.
