A 20mm CPVC elbow. It takes the run round a corner in one fitting, so the flow rate through the turn is set by the elbow's own geometry rather than by how well someone bent the pipe. It cements into the pipe socket with solvent, and the fitting is rated to PN 10, suitable for cold and hot duty. Chlorinating the PVC raises its temperature ceiling substantially. It looks similar to PVC and solvent-welds the same way, but it is doing a genuinely different job. Hot-water and heating duty, which is what the temperature rating on this range is for. Sold per piece and dimensionally matched to the rest of the CPVC range.
