50mm Metric 90° Elbow Fitting
SKU: PVC-EL90-50
- Professional Grade: Engineered for massive water volume management in large-scale reef and aquaculture systems.
- Metric Precision: Specifically sized for 50mm metric PVC pipe (approx. 2" OD), common on commercial Reef Octopus outlets.
- Space-Saving: Provides a sharp 90-degree turn to maximize space in high-flow filtration rooms and large sump layouts.
- Saltwater Tough: High-impact, industrial-grade grey PVC construction built for permanent saltwater immersion.
- Superior Seal: Deep-socket slip connections provide maximum surface area for a secure, leak-proof solvent weld.
- Ideal For: Commercial skimmer discharge; 50mm metric return manifolds; large-scale exhibit drain lines.
50mm Metric 90° Elbow Fitting
The 50mm Metric 90° Elbow is a robust plumbing component engineered for the most demanding water management tasks in professional aquarium and aquaculture installations. This fitting is specifically sized for 50mm 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 European life support systems.
In large-scale aquatic engineering, 50mm plumbing is the standard for handling extreme 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-pressure return lines or high-volume gravity drain applications. Constructed from industrial-grade, saltwater-safe grey PVC, this elbow features a smooth internal bore to minimize detritus buildup and ensures a permanent, high-strength bond when solvent-welded.
Key Features
True Metric Calibration: Fits 50mm OD metric pipe—essential for maintaining factory Reef Octopus commercial-spec plumbing.
Industrial Durability: Heavy-walled PVC construction designed to handle the high vibrations and pressures of large-scale pump rooms.
Flow-Optimized Bore: Precision-molded internal walls help maintain water velocity and reduce noise in high-volume plumbing runs.
Corrosion Proof: 100% non-metallic and saltwater safe; will not degrade or leach chemicals in marine environments.
Permanent High-Strength Weld: Slip x Slip configuration ensures a fail-safe connection with standard PVC solvent cement.
Ideal For
Commercial Skimmer Modification: Customizing the primary output of 50mm-diameter 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.

What’s Included:
(1) 50mm Metric 90° Elbow Fitting
Specifications:
Size: 50mm
Angle: 90 Degrees
Connection Type: Slip x Slip (Socket)
Material: Heavy-duty Grey PVC
Compatibility: 50mm Metric Pipe ONLY
- Ensure the 50mm 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 PVC solvent cement (suitable for large-diameter pipe) 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 seconds. Allow a minimum cure time of 2 hours before pressure testing.
Pro Tips
Metric vs. Standard 2-Inch.
A 50mm metric fitting will not fit standard 1.5" or 2" USA Schedule 40/80 pipe. 50mm is approximately 1.97 inches, whereas standard US 2" pipe has an outer diameter of 2.375". Always measure your pipe with a caliper before beginning a commercial installation.
Support the Weight. Large-diameter plumbing like 50mm 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 50mm fittings looking clean and "industrial," matching the professional aesthetic of high-end Reef Octopus life support systems.
