This PVC clamp for 20mm pipe controls thermal movement as well as weight. Both matter on long runs, and both are the clamp's job rather than the fitting's. The material is light, rigid and solvent-welded rather than mechanically joined, so a properly made PVC joint is effectively a continuous piece of pipe. Drainage duty — soil stacks, waste branches and rainwater runs. Rated to PN 10, with a solvent-socket connection.
