40mm Metric 90° Elbow Fitting
SKU: PVC-EL90-40
- Professional Grade: Engineered for high-volume water management in large-scale reef and aquaculture systems.
- Metric Precision: Specifically sized for 40mm metric PVC pipe (approx. 1.5" OD), the standard for large Reef Octopus discharge assemblies.
- Space-Saving: Provides a sharp 90-degree turn to maximize space in dense sump or cabinet plumbing layouts.
- Saltwater Tough: High-impact, industrial-grade grey PVC construction built for permanent marine use.
- Superior Seal: Deep-socket slip connections provide maximum surface area for a leak-proof solvent weld.
- Ideal For: Large skimmer outlets; 40mm metric return manifolds; high-flow drain lines.
40mm Metric 90° Elbow Fitting
The 40mm Metric 90° Elbow is a robust plumbing component designed for the most demanding water management tasks in large reef aquariums and commercial aquaculture installations. This fitting is precision-sized for 40mm Metric PVC pipe, which is the primary diameter used for the main discharge plumbing and gate valves on large-scale Reef Octopus Regal and Elite series protein skimmers.
In large-scale systems where space is at a premium but flow requirements are high, this 90-degree elbow allows you to route water effectively around tight corners or through cabinet bulkheads without the bulk of standard plumbing. Constructed from industrial-strength, saltwater-safe grey PVC, this elbow is engineered to handle the vibrations of high-wattage pumps and the corrosive nature of marine environments. The smooth internal bore is designed to reduce turbulence and prevent the accumulation of organic debris, ensuring your filtration system runs at peak efficiency.
Key Features
Accurate Metric Calibration: Fits 40mm OD metric pipe—essential for maintaining and modifying factory Reef Octopus hardware.
Industrial Durability: Heavy-walled PVC construction designed for high-pressure applications and resistance to environmental stress.
Flow-Optimized Bore: Precision-molded internal walls help maintain flow velocity and reduce noise in high-volume plumbing runs.
Corrosion Proof: 100% non-metallic and chemically inert; will not leach or degrade in saltwater.
Permanent High-Strength Weld: Slip x Slip configuration ensures a fail-safe connection with standard PVC solvent cement.
Ideal For
Large Skimmer Output Customization: Redirecting the primary discharge of 40mm Reef Octopus skimmers.
Commercial Return Manifolds: Routing high-volume flow for systems 250 gallons and larger.
Public Aquarium Displays: Heavy-duty plumbing for large-scale exhibit life support.

What’s Included:
(1) 40mm Metric 90° Elbow Fitting
Specifications:
Size: 40mm
Angle: 90 Degrees
Connection Type: Slip x Slip (Socket)
Material: High-grade Grey PVC
Compatibility: 40mm Metric Pipe ONLY
- Ensure the 40mm metric pipe is cut square and the edges are deburred with 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 layer of PVC primer to the pipe end and the internal socket of the fitting.
- Apply a liberal layer of 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 seconds. Allow a minimum cure time of 2 hours before pressure testing.
Pro Tips
Metric vs. Standard 1.5-Inch.
A 40mm metric fitting will not fit 1.25" or 1.5" USA Standard Schedule 40/80 pipe. 40mm is approximately 1.57 inches, whereas standard US 1.5" pipe has an outer diameter of 1.90 inches. Always measure your existing pipe with a caliper before beginning your installation.
Reduce Vibration Noise. In large 40mm plumbing runs, high-flow pumps can cause significant vibration. When using a 90-degree elbow near a pump, ensure the plumbing is properly supported with pipe hangers to prevent "pipe chatter" and stress on the solvent joints.
Industrial Aesthetic. Because these fittings are high-visibility grey, use clear PVC primer rather than the traditional purple variety. This results in a much cleaner, professional appearance that matches the professional look of high-end Reef Octopus life support systems.
