Important: Unlike injection-moulded fittings, these fittings are thermally formed from pipe. Dimensions and design may therefore vary slightly.
The PVC 90° bend in short design has the lowest resistance to flowing liquids compared to a PVC-U 90° Elbow or a PVC-U Short Bend. Every change in direction – and even every pipe – causes frictional resistance, which negatively affects the flow rate. When a liquid passes through fittings such as elbows, vortices occur that slow down the flow. The smoother the directional change – when comparing Elbow to Short Bend to Long Bend – the fewer vortices form, resulting in a more stable flow rate.
Long Bend vs Short Bend vs Elbow
The PVC-U elbow is certainly the most commonly used fitting, allowing a 90° turn over a short distance. Because of its compact shape, it is also known as a knee piece. PVC elbows or PVC knee fittings are the standard components in any piping system. Two elbows installed consecutively form a semicircle – i.e. a 180° change in direction – while opposite bonding creates an S-bend. Due to its low cost, the PVC-U elbow is the best choice when flow losses are not a concern.
However, high frictional resistance slows down the flow and leads to an unstable stream. In systems where a high and constant flow rate is required, PVC elbows are not ideal because the vortex formation inside the elbow significantly reduces the flow speed. Where high flow rates are crucial – for example with pumps that deliver a high volume but low head (e.g. pond systems) – PVC bends are the better option.
