About This Item
The Pentair Clamp Retaining Ring (24850-0016Z) is the OEM replacement clamp retaining ring for the Sta-Rite System 3 D.E., Modular Media, and Sand Filter series. This ring secures the filter's clamping assembly, maintaining the sealed integrity of the filter tank during operation.
⚠️ IMPORTANT: QUANTITY REQUIRED VARIES BY MODEL
The number of clamp retaining rings required depends on your specific filter model. System 3 Modular Media Filter model S7M120 requires 7 rings; model S8M150 requires 8 rings. System 3 Sand Filter model S7S50 uses seven rings; model S8S70 uses eight rings. This listing is for one (1) ring — order the correct quantity for your model before servicing.
The clamp retaining ring holds the filter tank clamp band in position, preventing lateral movement and ensuring the clamp applies even clamping force around the tank flange. A cracked, deformed, or missing retaining ring can allow the clamp to shift under pressure, compromising the tank seal. Replace this ring whenever the clamp assembly is serviced or when the ring shows visible deformation or cracking.

Pro Tip
Before ordering, confirm the number of clamp retaining rings your filter requires — this varies by model and the rings are sold individually. Count the existing rings on your filter's clamp band or check your equipment manual for the correct quantity. For the Modular Media Filter series, the S7-prefix models (S7M120, S7M400) use seven rings and the S8-prefix models (S8M150, S8M500) use eight. Ordering the full set at once avoids a second service call if a second ring is found damaged once the clamp is fully disassembled.
