110mm Metric 90° Elbow Fitting
SKU: PVC-EL90-110
- Engineered for high-volume water management in commercial-scale reef and aquaculture systems.
- Precision-molded 90° angle provides a sharp, space-saving turn for large-diameter plumbing runs.
- Designed specifically for 110mm metric PVC pipe (approx. 4.33" OD), common in heavy-duty Reef Octopus outlets.
- High-impact, industrial-grade grey PVC construction built for permanent saltwater immersion.
- Deep socket "slip" connections provide a massive surface area for a secure, leak-proof solvent weld.
- Ideal For: Commercial skimmer discharge; large exhibit drain lines; 110mm metric plumbing manifolds.
110mm Metric 90° Elbow Fitting
The 110mm Metric 90° Elbow is a heavy-duty plumbing component designed for massive water volume management in professional aquarium, public exhibit, and industrial aquaculture installations. This fitting is specifically sized for 110mm Metric PVC pipe, the primary diameter used for the main discharge assemblies and recirculating loops on large-scale Reef Octopus Commercial protein skimmers and high-capacity European life support systems.
In large-scale life support engineering, 110mm plumbing is used to handle extreme flow rates where standard plumbing would fail or cause significant restriction. This 90-degree fitting allows for clean, sharp turns in tight filtration rooms while maintaining the structural integrity required for high-pressure 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 110mm OD metric pipe—essential for maintaining factory Reef Octopus commercial-spec plumbing.
Space-Saving Design: Allows for 90-degree turns in dense plumbing layouts without sacrificing pipe diameter.
Industrial Grade PVC: Thick-walled construction designed to withstand the vibrations and pressures of high-capacity pump rooms.
Corrosion Proof: 100% saltwater safe and chemically inert; will not degrade or leach in marine environments.
Deep Socket Design: Slip x Slip configuration provides a massive surface area for a fail-safe solvent weld.
Ideal For
Commercial Skimmer Modification: Customizing the primary output of 110mm-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) 110mm Metric 90° Elbow Fitting
Specifications:
Size: 110mm
Angle: 90 Degrees
Connection Type: Slip x Slip (Socket)
Material: Heavy-duty Grey PVC
Compatibility: 110mm Metric Pipe ONLY
- Ensure the 110mm 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 (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 60 seconds. Allow a minimum cure time of 4–6 hours before pressure testing.
Pro Tips
Metric vs. Standard 4-Inch. A 110mm metric fitting will not fit standard 4-inch USA Schedule 40/80 pipe. 110mm is a specific metric outer diameter (approximately 4.33 inches), which is significantly larger than US 4-inch pipe (4.5 inch OD). Always measure your pipe with a caliper before beginning a commercial installation.
Support the Weight. Large-diameter plumbing like 110mm is extremely 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 110mm fittings looking clean and "industrial," matching the professional aesthetic of high-end Reef Octopus life support systems.
