25mm Metric 90° Elbow Fitting
The 25mm Metric 90° Elbow is a premium plumbing component designed for precision water routing in high-end marine and freshwater systems. This fitting is specifically sized for 25mm Metric PVC pipe, which is the primary diameter used for the discharge and recirculating lines on a wide variety of Reef Octopus protein skimmers and European-spec filtration equipment.
When plumbing a sump or an under-cabinet manifold, space is often at a premium. This 90-degree elbow allows you to route water around tight corners while maintaining the structural integrity required for pressurized lines. Constructed from heavy-duty, saltwater-safe grey PVC, this fitting is engineered to resist the corrosive effects of marine environments and the mechanical stress of continuous pump operation. The precision-molded internal walls ensure a seamless flow path, reducing noise and preventing organic buildup within the pipe.

Connection Type: Slip x Slip (Socket)
Material: Industrial Grade Grey PVC
Compatibility: 25mm Metric Pipe ONLY
- Ensure the 25mm metric pipe is cut perfectly square and any burrs are removed from the edges with a deburring tool.
- Perform a dry-fit of the 90° elbow to verify the alignment of your plumbing run before applying adhesive.
- Apply a layer of PVC primer to the outside of the pipe and the internal socket of the fitting.
- Apply a thin, even coat of PVC solvent cement to both the pipe end and the elbow socket.
- Insert the pipe firmly into the elbow with a quick quarter-turn to distribute the glue.
- Hold the joint together for 20 seconds. Allow a minimum of 1 hour for the joint to cure before introducing water pressure.
Pro Tips
Confirm Your Diameter. A 25mm metric fitting will not fit 3/4" or 1" USA standard Schedule 40/80 pipe. 25mm is approximately 0.98 inches. Standard 1" pipe has an outer diameter of 1.315", so they are not interchangeable. Always use a caliper to confirm your pipe size if you are unsure of its origin.
Reduce Splash Noise. If you are using a 90-degree elbow for a skimmer discharge, ensure the exit is submerged or angled against the sump wall to minimize splashing and micro-bubbles.
Professional Aesthetics. Because these fittings are a high-visibility grey, using clear PVC primer rather than purple will keep your plumbing looking clean and professional. This matches the factory aesthetic of Reef Octopus equipment, making your DIY plumbing look like a factory installation.
