The S30 Series is a special purpose, double shut-off fluid transfer quick coupling that provides significantly less pressure drop than couplings of the same type produced by other manufacturers. A threaded sleeve locking mechanism mates the coupling halves and allows connection under pressure up to a maximum of 1,000 psi. Our heavy-duty poppet valving, while fully interchangeable with ball check models (including older SafeWay product), eliminates low pressure leakage. The S30 is designed for extreme high pressure applications including portable hydraulic rams, wire pullers, and frame straightening equipment.
