The pressure values for copper alloy connectors and tubes were produced using brass connectors with phosphorescent soft-annealed copper tubing.
a Metric tubing shall be preferred.
b For working pressure applications higher than those given in Table 1, the manufacturer shall be consulted.
c 1 bar = 10 5 N/m 2 = 10 5 Pa = 0,1 MPa.
