A 20mm CPVC adaptor, for connecting two different jointing systems. Every installation has at least one of these, usually at the appliance or the meter. CPVC holds its strength at temperatures that soften ordinary PVC. That single difference is why it is used on hot feeds where uPVC would not be suitable at all. It cements into the pipe socket with solvent, and the fitting is rated to PN 10, suitable for cold and hot duty. Suited to hot-water distribution and heating circuits.
