110mm Metric Tee Fitting
SKU: PVC-TEE-110
- High-Flow Distribution: Enables the creation of 90-degree branches in 110mm metric plumbing lines for complex commercial manifolds.
- Commercial Capacity: Sized specifically for 110mm metric PVC pipe (approx. 4.33" OD), the standard for massive Reef Octopus life support discharge.
- Industrial Build: Constructed from thick-walled, high-impact grey UPVC for superior pressure resistance and long-term structural integrity.
- Saltwater Proof: 100% non-corrosive and chemically inert; safe for permanent immersion in large-scale marine exhibits and aquaculture.
- Professional Finish: Smooth internal bore minimizes turbulence and head loss in high-volume water transport systems.
- Ideal For: Creating manifold take-offs; splitting main discharge lines; installing sensors or bypass loops in 110mm runs.

110mm Metric Tee Fitting
The 110mm Metric Tee Fitting is a heavy-duty structural component designed for high-volume water distribution in professional aquarium exhibits, public aquariums, and industrial aquaculture facilities. Precision-molded for 110mm Metric PVC pipe, this 3-way joiner is a critical part of the primary life support infrastructure, allowing for the branching of main return headers and the construction of large-scale filtration manifolds.
In commercial-grade life support engineering, fittings must withstand immense hydraulic surges and the significant weight of water-filled 110mm plumbing. This tee features exceptionally deep sockets, providing the massive surface area required for secure solvent welding. Manufactured from industrial-grade grey UPVC, it matches the professional "factory" aesthetic of Reef Octopus commercial equipment and is built to withstand the rigors of high-pressure pump rooms.
Key Features
True Metric Calibration: Fits 110mm OD metric pipe—the standard for Reef Octopus commercial-spec and European large-scale hardware.
Hydraulic Optimization: The smooth 90-degree internal transition is designed to maintain flow velocity while minimizing friction loss.
Marine-Grade Material: 100% non-metallic; will not rust, pit, or leach chemicals into sensitive aquatic environments.
Heavy-Wall Construction: Engineered to handle the mechanical stresses and vibrations common in industrial filtration racks.
Slip x Slip x Slip: Features three female socket connections for permanent, leak-proof solvent welding on all ends.
Ideal For
Commercial Manifolds: Creating 110mm distribution blocks for multi-tank systems or public exhibits.
Bypass Loops: Installing maintenance bypasses or sensor arrays on primary 110mm life support lines.
Drainage Systems: Branching main 110mm gravity-drain headers for high-volume water evacuation.

What’s Included:
(1) 110mm Metric Tee Fitting
Specifications:
Size: 110mm
Connection Type: Slip x Slip x Slip (Socket)
Material: Industrial Grade Grey UPVC
Compatibility: 110mm Metric Pipe ONLY
- Ensure all 110mm metric pipe ends are cut perfectly square and thoroughly deburred.
- Clean the pipe ends and the internal sockets of the tee with a dedicated PVC cleaner.
- Apply a layer of PVC primer to the pipe ends and all three internal sockets of the tee.
- Apply a liberal coat of heavy-duty solvent cement (specifically rated for large-diameter pipe) to both components.
- Push the pipes into the tee until they seat fully, giving a slight quarter-turn to ensure even glue distribution.
- Hold firmly for 60 seconds per joint. Allow at least 8–12 hours to cure before introducing high-pressure water.
Pro Tips:
- Metric vs. Standard 4-Inch. A 110mm metric tee will not fit standard US 4-inch pipe. 110mm is approximately 4.33 inches, while US 4-inch pipe has a 4.5-inch OD. Always verify your pipe diameter with a caliper before beginning a permanent installation.
- The Support Requirement. Due to the size and weight of 110mm plumbing, it is critical to use 110mm Pipe Carriers on all three sides of the tee. This prevents the weight of the water-filled pipes from stressing the solvent joints over time.
- Clean Aesthetics. Use clear PVC primer instead of 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.
