Reef Octopus Classic 150-S Collection Cup O-Ring
The Reef Octopus Classic 150-S Collection Cup O-Ring (SKU: ROP-CC-ORING150S) is a precision-engineered sealing component vital for the efficient operation of your protein skimmer. Positioned at the neck where the collection cup joins the skimmer body, this O-ring creates a critical airtight seal. If this seal is compromised, air escapes from the junction, causing the foam column to lose stability and significantly decreasing the skimmer's ability to export organic waste.
Specifically sized for the "Super Space Saver" (SSS) version of the Classic 150, this O-ring ensures that 100% of the air-water mixture is directed into the collection cup. Over time, constant exposure to saltwater and regular cleaning can cause the original rubber to become brittle or flattened. Replacing this O-ring eliminates unsightly salt creep on the exterior of the skimmer and restores the smooth, secure fit of the collection cup.
Key Features
• Precision Fit: Specifically engineered for the 6-inch neck dimensions of the Classic 150-S (CLSC-150SSS).
• Airtight Performance: Seals the reaction chamber to maintain the internal pressure necessary for thick foam.
• Saltwater Resistant: Manufactured from high-grade rubber designed for longevity in marine environments.
• Prevents Salt Creep: Stops the slow "weeping" of skimmate that leads to salt buildup at the neck.
• OEM Quality: Genuine Reef Octopus part ensures factory-standard performance and reliability.
Ideal For
• Classic 150-S Owners: Directly compatible with the 150-series space-saving internal skimmer.
• Leaking Skimmer Necks: Fixing units where bubbles or skimmate are escaping from the cup junction.
• Annual Refurbishing: A cost-effective part to replace during yearly deep-cleaning of your filtration system.
• Restoring Friction Fit: Returning the secure, stable feel when seating the collection cup.

- Turn off the protein skimmer pump.
- Carefully remove the collection cup by lifting it vertically.
- Locate the old O-ring on the neck of the skimmer body.
- Remove the old O-ring and clean the groove with a damp cloth to remove any salt or debris.
- Slide the new O-ring into the groove, ensuring it is seated evenly and not twisted.
- Reinstall the collection cup and restart the pump.
Pro Tips:
Use Silicone Lubricant.
Apply a light coating of aquarium-safe silicone lubricant to the O-ring before installation. This prevents the rubber from bonding to the acrylic, making the cup much easier to remove for cleaning and protecting the O-ring from tearing.
Eliminate "Gurgling" Sounds. If you hear a gurgling sound coming from the neck of your skimmer, it is often air escaping past a dry or damaged O-ring. A quick replacement often resolves this noise issue immediately.
Check the Fit. When seating the cup, you should feel a firm, consistent resistance. If the cup feels loose or wobbles, the O-ring is likely flattened and needs replacement to prevent air bypass.
