REHAU announced the addition of R-20 manifold connectors to its EVERLOC+ compression-sleeve fitting line. The new R-20 connectors are designed for use with RAUPEX crosslinked polyethylene (PEXa) pipes and PRO-BALANCE manifolds. Machined from solid brass with a nickel-plated swivel nut, the manifold outlets are available in 3/8”, 1/2”, 5/8” and 3/4”sizes. The design features reconfigured bushings for increased accessibility when using larger hydronic circuits. All EVERLOC+ R-20 fittings include an EVERLOC+ insert with a pre-installed O-ring and swivel nut in a one-piece assembly to support connection security. The R-20 fitting uses the swivel nut to connect to the manifold, then joins to the hydronic circuits using the EVERLOC+ connection technology.
