Product usage precautions

Note 1: Fittings without a thread portion and with all resin bodies are copper free specifications.
Note 2: The surge pressure must be under the maximum operating pressure.
Note 3: Do not use the fittings with a leak tester or for vacuum retention because they are not guaranteed for zero leakage.
Note 4: øD1 and øD2 are the maximum diameters.
