SKU: PVC-CPLG-110
- Seamless Connection: Designed to join two lengths of 110mm metric pipe with a permanent, high-strength solvent weld.
- Commercial Capacity: Sized specifically for 110mm metric PVC pipe (approx. 4.33" OD), the industrial standard for Reef Octopus life support.
- Full-Flow Interior: Features a smooth internal bore with a center stop to ensure perfect alignment and zero flow restriction.
- Industrial Durability: Constructed from thick-walled, high-impact grey UPVC for superior pressure and chemical resistance.
- Saltwater Proof: 100% non-corrosive; engineered for permanent immersion or high-humidity pump room environments.
- Ideal For: Extending long 110mm pipe runs; repairing main discharge lines; manifold construction.
Reef Octopus
Globally trusted for premium protein skimmers and pumps, engineered in-house for unmatched reef filtration performance.
110mm Metric Standard Coupling
The 110mm Metric Standard Coupling is a heavy-duty straight joiner engineered for the permanent connection of large-diameter plumbing in professional aquarium exhibits and industrial aquaculture facilities. Precision-molded for 110mm Metric PVC pipe, this fitting is the primary method for extending main discharge assemblies and recirculating loops on Reef Octopus Commercial protein skimmers.
In large-scale life support engineering, structural integrity is non-negotiable. This coupling features deep sockets and a thick-walled UPVC construction designed to handle the significant weight and hydraulic pressure of 110mm plumbing systems. The internal center stop (bridge) ensures that both pipe ends are inserted to the correct depth, creating a symmetrical, high-strength bond that effectively becomes as strong as the pipe itself. Finished in industrial grey, it provides a professional aesthetic that matches high-end commercial filtration equipment.
Key Features
True Metric Calibration: Fits 110mm OD metric pipe—the standard for Reef Octopus commercial-spec and European large-scale hardware.
Zero-Leak Construction: Deep slip-fit sockets provide a massive surface area for a permanent, high-pressure solvent weld.
Hydraulic Efficiency: The internal diameter matches the pipe's bore, preventing turbulence or pressure drops in your main lines.
Marine Grade Material: 100% saltwater safe; will not rust, degrade, or leach chemicals into sensitive aquatic exhibits.
High-Impact Resistance: Built to withstand the environmental stresses and vibrations common in commercial pump rooms.
Ideal For
Main Exhibit Plumbing: Extending 110mm return or drain lines across long facility spans.
Manifold Construction: Joining valves and specialized fittings in high-volume distribution blocks.
System Repairs: Splicing in new sections of 110mm pipe during filtration upgrades or modifications.

What’s Included:
(1) 110mm Metric Standard Coupling
Specifications:
Size: 110mm
Connection Type: Slip x Slip (Socket)
Material: Industrial Grade Grey UPVC
Compatibility: 110mm Metric Pipe ONLY
- Ensure both 110mm metric pipe ends are cut square and thoroughly deburred.
- Clean the pipe ends and the internal sockets of the coupling with a dedicated PVC cleaner.
- Apply a layer of PVC primer to both the pipe ends and the inside of the coupling.
- Apply heavy-duty PVC solvent cement (rated for large-diameter pipe) to both the pipe and the coupling sockets.
- Push the pipes into the coupling until they hit the center stop, giving a slight quarter-turn to ensure even glue distribution.
- Hold firmly for 60 seconds. Allow at least 6–8 hours to cure before introducing high-pressure water flow.
Pro Tips:
- Metric vs. Standard 4-Inch. A 110mm metric coupling will not fit standard 4-inch USA pipe. 110mm is approximately 4.33 inches, while US 4-inch pipe has a 4.5-inch OD. Always verify your pipe diameter with a caliper before beginning a permanent solvent weld.
- Don't Skip the Primer. On 110mm pipe, the surface area for the bond is massive. Using a quality primer is essential to "soften" the UPVC, allowing the solvent cement to create a true chemical weld that can handle commercial pressures.
- Aesthetic Consistency. For a clean, professional finish that matches factory Reef Octopus gear, use clear PVC primer rather than purple. This prevents messy stains on the grey fittings and maintains a sleek, industrial look in your filtration room.
