40/25mm Metric Reducing Tee Fitting
SKU: PVC-RDTEE-4025
- High-Flow Manifold Design: Permits seamless integration of a 25mm auxiliary branch off a primary 40mm main water line.
- Triple Slip Sockets: Features smooth female slip connections on all three ports, designed for permanent, leak-free solvent-welded joints.
- Aquarium-Grade Dark Gray Finish: Neutral industrial aesthetic matches professional sumps, reef reactors, and custom under-cabinet manifolds.
- 100% Reef Safe Construction: Molded from premium, virgin uPVC entirely free from heavy metal stabilizers and plasticizers.
- Heavy-Wall Structure: Injection-molded with high-thickness unplasticized PVC to prevent stress cracking from water hammer and structural vibration.
CoralVue 40/25mm Metric Reducing Tee (SKU: PVC-RDTEE-4025)
The CoralVue 40/25mm Metric Reducing Tee (SKU: PVC-RDTEE-4025) is a premium, professional-grade fluid management component engineered for building advanced aquarium return manifolds. Setting up a high-performance marine system often requires feeding multiple auxiliary components, such as calcium reactors, algae scrubbers, UV sterilizers, or media cups. Attempting to use multiple individual reducers and standard tees consumes valuable space and creates unnecessary friction. This integrated, single-piece reducing tee solves that issue by splitting a compact 25mm branch takeoff directly from your main 40mm plumbing loop.
Molded to precise aquaculture tolerances, this dark gray uPVC fitting features smooth female slip sockets on all three ports. By solvent welding this fitting inline, you maintain a robust 40mm flow path for your main return while creating a dedicated port for auxiliary equipment. The interior branch entry features a smooth, swept transition to minimize dynamic friction, ensuring your main pump's kinetic energy is preserved while providing reliable pressure to the auxiliary branch.
Key Features
Built-in Landing Shoulders: Molded internal pipe stops inside all three ports prevent over-insertion, ensuring consistent solvent-weld depth.
Compact Footprint: Eliminates the bulk of a standard tee combined with separate reduction bushings, saving valuable space inside tight aquarium stands.
Exceptional Chemical Resistance: Formulated from uPVC to withstand aggressive marine salts, ozone, and typical chemical aquarium additives.
(Note: This retail SKU contains (1) individual standalone CoralVue 40/25mm Reducing Tee. Solvent primers, cements, and rigid piping are sold under separate product categories).

- Ensure all metric rigid pipes (two 40mm and one 25mm) are cut squarely at a true 90-degree angle and completely deburred.
- Thoroughly clean the interior sockets of the reducing tee and the exterior tips of the mating pipes using a clean, dry cloth.
- Apply a thin, even layer of PVC primer to the inside of the tee sockets and the outside of the pipe ends.
- While wet, apply PVC solvent cement over the primed areas.
- Insert the pipes firmly into their respective sockets, rotating each roughly 1/4 turn to distribute the cement evenly.
- Hold each joint under firm pressure for 15 to 20 seconds to prevent the pipe from backing out while the cement sets.
- Allow the plumbing assembly to cure undisturbed for a full 24 hours before filling with saltwater or testing under dynamic system pressure.
- Do Not Attempt to Glue Imperial Pipe Directly Into This Metric Fitting.
CRITICAL AQUARIUM PLUMBING DESIGN TIP: This reducing tee is engineered to exact metric dimensions. The slip ports accept only standard 40mm and 25mm metric rigid pipes. Do not attempt to force standard domestic 1-1/4" or 3/4" Schedule 40 or Schedule 80 pipe into the sockets. The dimensional variances will cause structural joint failure or immediate leaks under pressure.
- Use Ball Valves on Your Auxiliary Branch Line. When tapping a 25mm line off your main 40mm return line using this reducing tee, always install a high-quality metric ball valve (or gate valve) on the 25mm branch run. This allows you to fine-tune the exact water volume feeding your reactor or UV sterilizer without altering the main return flow back into the display tank.
- Plan Manifold Spacing Wisely. When building a multi-port manifold using several reducing tees in a row, allow at least 2 inches of straight 40mm pipe between each tee. This gives you enough clearance to install pipe hangers or secure the manifold to your cabinet walls, keeping the plumbing run neat, concentric, and secure.
