- Grey sub, blue nut.
- O-ring mounted sub provides excellent sealing properties.
- Temperature rating: -25 deg. F to 200 deg. F
- Note: 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.
- 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 deg.
