63mm Metric Pipe Cap
SKU: PVC-CAP-63
- Commercial Termination: Provides a permanent, high-strength seal for the end of 63mm metric PVC plumbing runs.
- Metric Precision: Sized specifically for 63mm metric pipe (approx. 2.5" OD), a standard for commercial Reef Octopus discharge assemblies.
- Industrial Strength: Manufactured from high-impact, thick-walled grey UPVC for maximum durability in professional pump rooms.
- Saltwater Safe: 100% non-corrosive and chemically inert; won't leach toxins into sensitive reef environments or aquaculture systems.
- Professional Finish: Smooth, rounded exterior prevents snags and provides a clean aesthetic for large-scale filtration racks.
- Ideal For: Sealing 63mm manifold headers; capping unused commercial skimmer ports; industrial pressure testing.
63mm Metric Pipe Cap
The 63mm Metric Pipe Cap is a high-capacity termination fitting engineered for professional water management in large-scale aquarium systems, public exhibits, and aquaculture facilities. Specifically designed for 63mm Metric PVC pipe, this cap is the industry-standard solution for sealing the ends of primary manifold headers or closing off large discharge ports on commercial Reef Octopus protein skimmers.
In high-volume life support systems, the integrity of every termination is critical to prevent significant leaks and maintain system pressure. This cap is built to withstand the heavy vibrations and water hammer typical of 63mm plumbing runs powered by high-performance commercial pumps. Constructed from industrial-grade grey UPVC, it provides significantly better impact resistance than standard white residential fittings and perfectly matches the "factory" aesthetic of professional filtration equipment.
Key Features
True Metric Calibration: Fits 63mm OD metric pipe—essential for maintaining and modifying commercial Reef Octopus and European-spec systems.
Heavy-Duty Construction: Industrial UPVC is designed for permanent immersion in saltwater without degradation or chemical leaching.
Precision Interior: Molded to ensure a square, full-depth seat on the pipe, ensuring a straight and professional-looking termination.
High-Surface Bonding: The deep socket provides a massive surface area for a secure, permanent solvent weld.
Streamlined Design: The low-profile, rounded exterior is ideal for clean plumbing runs in tight filtration racks.
Ideal For
Commercial Manifolds: Permanently sealing the ends of 63mm distribution blocks.
Industrial Skimmers: Closing off unused recirculation or drain ports on large-body Reef Octopus units.
LSS Expansion: Capping off 63mm "stubs" designed for future filtration modules or exhibit tanks.

What’s Included:
(1) 63mm Metric Pipe Cap
Specifications:
Size: 63mm
Connection Type: Slip (Socket)
Material: Industrial Grade Grey UPVC
Compatibility: 63mm Metric Pipe ONLY
- Ensure the 63mm metric pipe end is cut perfectly square and thoroughly deburred.
- Perform a dry-fit to confirm the pipe reaches the bottom of the internal socket.
- Apply a generous layer of PVC primer to the pipe end and the internal socket of the cap.
- Apply a liberal coat of heavy-duty solvent cement to both components.
- Push the cap onto the pipe and rotate slightly (approx. 1/4 turn) to ensure even glue distribution.
- Hold firmly for 60 seconds. Allow at least 6 hours of cure time before introducing high-pressure water.
Pro Tips:
- Metric vs. Standard 2.5-Inch. A 63mm metric cap will not fit standard 2-inch or 2.5-inch USA Schedule 40/80 pipe. 63mm is approximately 2.48 inches, while standard US 2.5" pipe has an outer diameter of 2.875 inches. Always verify your pipe size with a caliper before beginning a commercial installation.
- The Union Strategy. If you are capping a main line that you expect to expand later, consider installing a 63mm Metric Union just before the cap. This allows you to unscrew the cap and continue your plumbing run in the future without needing to cut your main header.
- Aesthetic Consistency. Use clear PVC primer rather than 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.
