Three-way CPVC tee in 20mm. Use it wherever a line has to serve two destinations rather than one — the most-used fitting in most distribution layouts after the elbow. 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. Rated to PN 10, with a solvent-socket connection, suitable for cold and hot duty. It belongs on hot-water and heating service, including radiator and underfloor circuits. Sold per piece and dimensionally matched to the rest of the CPVC range.
