DIY aquarium builders, pond keepers, and water tank installers need a bulkhead fitting that threads in once and stays watertight — without cracking, corroding, or warping over time. These PVC 90° elbow pipe fittings are engineered for exactly that job.\u003c\/p\u003e\n    \u003cp\u003eEach fitting is molded from Polyvinyl Chloride (PVC), a rigid, chemical-resistant thermoplastic that holds its shape under sustained water pressure. The grey finish blends cleanly into tank walls and plumbing runs. Inner diameters span 20mm (~¾ in) through 50mm (~2 in), covering the most common pipe sizes used in aquarium sumps, IBC tote outlets, rainwater harvesting tanks, and irrigation manifolds. Wall thickness is proportional to pipe size, typically 2–4mm, ensuring a secure threaded or push-fit seal.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include: routing overflow lines through aquarium sump walls using a 20mm or 25mm bulkhead elbow; connecting 32mm or 40mm drainage pipes at a 90° turn in a greenhouse irrigation system; and installing 50mm tank outlet elbows on IBC totes or large water storage containers for gravity-fed distribution.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard PVC pipe with matching inner diameter (20 \/ 25 \/ 32 \/ 40 \/ 50mm).
