20mm Metric Tee Fitting
SKU: PVC-TEE-20
- Versatile Branching: Allows for the creation of 90-degree lateral branches in 20mm metric plumbing lines.
- Precision Metric Fit: Sized specifically for 20mm metric PVC pipe (approx. 0.78" OD), the standard for Reef Octopus skimmer and reactor plumbing.
- Industrial Durability: Constructed from heavy-walled, high-impact grey UPVC for superior strength compared to standard residential fittings.
- Saltwater Safe: 100% non-corrosive and chemically inert; safe for sensitive reef systems and specialized aquatic life.
- High-Flow Interior: Smooth internal transitions minimize turbulence and maintain water velocity through the branch.
- Ideal For: Creating manifold take-offs; splitting feed lines for media reactors; custom Reef Octopus skimmer modifications.
Reef Octopus
Globally trusted for premium protein skimmers and pumps, engineered in-house for unmatched reef filtration performance.
20mm Metric Tee Fitting
The 20mm Metric Tee Fitting is a professional-grade 3-way joiner designed for complex water distribution in modern aquarium systems. Precision-molded for 20mm Metric PVC pipe, this tee is a fundamental component for building custom manifolds, branching feed lines to multiple reactors, or modifying the internal plumbing of Reef Octopus protein skimmers.
In high-end reef plumbing, precision and reliability are paramount. This tee features deep slip-fit sockets that provide a large surface area for solvent welding, ensuring a permanent, leak-proof bond. Unlike common white PVC fittings, this component is made from industrial-grade grey UPVC, which offers higher impact resistance and an aesthetic that perfectly matches factory-spec European filtration hardware. Its compact design makes it ideal for use in the tight confines of an aquarium cabinet or sump area.
Key Features
True Metric Calibration: Fits 20mm OD metric pipe—essential for maintaining factory Reef Octopus and European-spec hardware.
90-Degree Precision: Ensures perfectly square branches for clean, organized plumbing layouts.
Marine-Grade Material: 100% non-metallic; will not rust, degrade, or leach harmful chemicals into the water column.
Full-Flow Design: Engineered to maintain hydraulic efficiency across the branch, reducing head pressure on your pumps.
Slip x Slip x Slip: Features three female socket connections for permanent chemical welding on all sides.
Ideal For
Dosing & Feed Manifolds: Splitting a single 20mm feed line into multiple reactor branches.
Skimmer Customization: Adding or modifying recirculating loops on Reef Octopus skimmer bodies.
Sensor Integration: Providing a branch point for inline probe holders or flow meters.

What’s Included:
(1) 20mm Metric Tee Fitting
Specifications:
Size: 20mm
Connection Type: Slip x Slip x Slip (Socket)
Material: Industrial Grade Grey UPVC
Compatibility: 20mm Metric Pipe ONLY
- Ensure all three 20mm 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 light coat of PVC solvent cement to both the pipe and the sockets.
- Push the pipes into the tee until they seat fully, giving a slight quarter-turn to distribute the cement.
- Hold firmly for 30 seconds. Allow at least 1 hour of cure time before introducing water pressure.
Pro Tips:
- Metric vs. Standard. A 20mm metric tee will not fit 1/2" or 3/4" USA standard pipe. 20mm is approximately 0.78 inches. Always verify your pipe diameter with a caliper to ensure you are using metric components.
- The "Clean Look" Strategy. To maintain the professional, industrial look of your grey UPVC plumbing, use clear PVC primer rather than the common purple variety. This prevents unsightly stains on the fittings and keeps your sump area looking like a factory Reef Octopus installation.
- Support Your Branches. Even with small 20mm plumbing, weight can add up. Use 20mm Metric Pipe Carriers near the tee to prevent the weight of the water-filled pipes from putting leverage stress on your solvent joints.
