Socket weld configurations and other materials are available.
Hammer unions work at extremely high pressures. Mismatching components of one series with another (i.e. series 602 with series 1502) can lead to destruction of property, serious bodily injury or death.
Temperature rating: -25°F to 200°F
Note: non-shocking cold water pressure means that the rated value is the maximum pressure at ambient temperature:
no spikes higher than this pressure
no instantaneous pressure increases (0-2000 PSIG in 1/4 of a second)
ambient temperature: 70°F
