110mm Metric Pipe Cap
SKU: PVC-CAP-110
- Leak-Proof Termination: Provides a permanent, high-strength seal for the end of 110mm metric piping runs.
- Commercial Capacity: Sized specifically for 110mm metric PVC pipe (approx. 4.33" OD), the industrial standard for Reef Octopus life support.
- Heavy-Duty Build: Constructed from high-impact, industrial-grade grey PVC for superior pressure resistance.
- Saltwater Tough: 100% non-corrosive material, engineered for permanent immersion in high-flow marine environments.
- Clean Design: Smooth, rounded exterior prevents snagging and provides a professional finish to commercial plumbing racks.
- Ideal For: Capping manifold branches; sealing unused skimmer ports; pressure testing 110mm metric lines.
110mm Metric Pipe Cap
The 110mm Metric Pipe Cap is a robust termination component designed for large-scale water management in professional aquarium exhibits and industrial aquaculture facilities. Precision-engineered for 110mm Metric PVC pipe, this fitting is the standard solution for sealing the ends of main discharge lines, recirculating loops, and manifold headers on Reef Octopus Commercial protein skimmers.
In complex life support engineering, pipe caps are essential for closing off unused ports in a manifold or providing a permanent seal for lines intended for future expansion. Constructed from industrial-grade, thick-walled grey PVC, this cap provides the structural integrity necessary to withstand the significant internal pressure and water hammer common in high-diameter plumbing systems. The deep socket design ensures a maximum bonding surface for solvent welding, resulting in a fail-safe termination.
Key Features
True Metric Calibration: Fits 110mm OD metric pipe—standard for Reef Octopus commercial-spec plumbing and large European exhibit builds.
Industrial Strength: Rated for high-pressure applications and built to endure the rigors of commercial pump rooms.
Corrosion Proof: 100% saltwater safe; will not rust, degrade, or leach chemicals into sensitive aquatic environments.
Precision Molded: Smooth internal socket ensures a snug fit for easy alignment during the solvent welding process.
Deep Socket Design: Provides a massive surface area for a secure, permanent solvent weld.
Ideal For
Manifold Termination: Sealing the end of a 110mm distribution header.
System Expansion: Capping off "stub-outs" designed for future filtration modules.
Commercial Skimmer Maintenance: Sealing secondary ports on large-body Reef Octopus commercial skimmers.

What’s Included:
(1) 110mm Metric Pipe Cap
Specifications:
Size: 110mm
Connection Type: Slip (Socket)
Material: Industrial Grade Grey PVC
Compatibility: 110mm Metric Pipe ONLY
- Ensure the 110mm metric pipe end is cut square and deburred thoroughly.
- Perform a dry-fit to ensure the pipe seats fully into the bottom of the cap.
- Apply a generous layer of PVC primer to the pipe end and the internal socket of the cap.
- Apply heavy-duty solvent cement (specifically rated for large-diameter pipe) to both components.
- Push the cap onto the pipe with a slight quarter-turn to ensure the adhesive is fully distributed.
- Hold firmly for 60 seconds. Allow at least 6 hours to cure before introducing high-pressure water.
Pro Tips:
- Metric vs. Standard 4-Inch. A 110mm metric fitting will not fit standard 4-inch USA pipe. 110mm is approximately 4.33 inches, whereas US 4-inch pipe has a 4.5-inch OD. Always verify your pipe diameter with a caliper before beginning your installation.
- Temporary vs. Permanent. If you are using this cap for temporary pressure testing or plan to expand the line later, consider using a short "stub" of pipe and a union before the cap. This allows you to remove the cap later without having to cut into your main 110mm header.
- Professional Aesthetics. Use clear PVC primer instead of purple to maintain the professional, industrial look of the grey UPVC. This matches the factory aesthetic of high-end commercial Reef Octopus equipment for a clean, professional finish.
