63mm Metric 90° Elbow Fitting
SKU: PVC-EL90-63
- Professional Grade: Engineered for massive water volume management in large-scale reef and aquaculture systems.
- Metric Precision: Specifically sized for 63mm metric PVC pipe (approx. 2.5" OD), common on high-capacity commercial Reef Octopus outlets.
- Space-Saving: Provides a sharp 90-degree turn to maximize space in high-flow filtration rooms and large sump layouts.
- Industrial Strength: Stronger and more professional look than standard white Schedule 40 PVC.
- Superior Seal: Slip-to-slip socket connections provide maximum surface area for a secure, leak-proof solvent weld.
- Ideal For: Commercial skimmer discharge; 63mm metric return manifolds; large-scale exhibit drain lines.
63mm Metric 90° Elbow Fitting
The 63mm Metric 90° Elbow is a robust UPVC plumbing component designed for the most demanding water management tasks in professional aquarium and aquaculture installations. This fitting is specifically sized for 63mm Metric PVC pipe, the primary diameter used for the main discharge assemblies and recirculating loops on large-scale Reef Octopus commercial protein skimmers and heavy-duty life support systems.
In large-scale aquatic engineering, metric UPVC is the standard for handling high flow rates without excessive backpressure. This 90-degree fitting allows for clean, sharp turns in dense filtration rooms while maintaining the structural integrity required for high-volume gravity drain or pressure applications. Constructed from industrial-grade grey PVC, this elbow offers superior chemical and corrosion resistance, ensuring a long service life in harsh saltwater environments.
Key Features
True Metric Calibration: Fits 63mm OD metric pipe—essential for maintaining factory Reef Octopus commercial-spec plumbing.
Industrial Durability: Schedule 80/PN-16 rating provides a much stronger build than standard residential PVC.
Flow-Optimized Design: Plain internal bore facilitates a smooth and secure connection while maintaining optimal flow.
Corrosion Proof: High-quality UPVC construction is safe for marine life and will not degrade or leach chemicals.
Professional Appearance: Dark grey finish provides a cleaner, more industrial look compared to white Schedule 40 PVC.
Ideal For
Commercial Skimmer Customization: Modifying or repairing the primary output of large Reef Octopus skimmers.
Large-Scale Drain Lines: Routing high-volume gravity drains for massive exhibits and public aquarium displays.
Centralized Filtration: Creating professional, high-diameter plumbing manifolds for industrial aquaculture racks.

(1) 63mm Metric 90° Elbow Fitting
Specifications:
Size: 63mm
Angle: 90 Degrees
Connection Type: Slip x Slip (Socket)
Material: Industrial Grade Grey UPVC
Rating: Schedule 80 / PN-16
Compatibility: 63mm Metric Pipe ONLY
- Ensure the 63mm metric pipe is cut perfectly square and deburred using a specialized tool or sandpaper.
- Perform a dry-fit of the 90° elbow to verify the alignment of your large-diameter plumbing run.
- Apply a generous coat of PVC primer to the pipe end and the internal socket of the fitting.
- Apply a liberal layer of heavy-duty PVC solvent cement to both the pipe and the elbow.
- Insert the pipe into the fitting and give it a slight quarter-turn to ensure the adhesive is fully distributed.
- Hold firmly for 30–60 seconds. Allow a minimum cure time of 2 hours before pressure testing.
Pro Tips
Metric vs. Standard 2.5-Inch.
A 63mm metric fitting will not fit standard 2-inch or 2.5-inch USA Schedule 40/80 pipe. 63mm is a specific metric outer diameter (approximately 2.48 inches). Always measure your pipe with a caliper to ensure you are working with metric components before applying adhesive.
Support the Weight. Large-diameter plumbing like 63mm is heavy when filled with water. Ensure that your plumbing run is supported by pipe hangers or brackets every few feet to prevent stress on the 90-degree solvent joints.
Professional Aesthetics. In high-visibility commercial installs, use clear PVC primer rather than purple. This keeps the grey 63mm fittings looking clean and "industrial," matching the professional aesthetic of high-end Reef Octopus life support systems.
