OASE Connection Pipe Black (DN110/75/50) for pond plumbing
These black PVC-U connection pieces are the unglamorous parts that make a pond filter system actually work: angled elbows in DN110, DN75 and DN50 sizes that let you route gravity-fed flow around tight corners between pump, filter box and waterfall. Made from PVC-U, they match standard OASE pipe diameters so your joins stay secure and watertight rather than relying on improvised fittings that leak.
In a Singapore landed-home or courtyard pond, plumbing usually has to snake through planters, paving and limited side-of-house space, so having the correct 45-degree and reducing elbows on hand saves you forcing pipe at awkward angles. Dry-fit the run first, account for the slight head loss every bend adds to your pump’s flow, and seal joints properly so the system holds during heavy monsoon downpours when water levels and pressure fluctuate.
Find matching pipe, pumps and filters under cleaning & maintenance. For overall system design, read our complete pond filtration guide and how to build a garden pond in Singapore.
