Threaded Couplings

Applications involving higher fluid pressure or vibration require couplings offering a more secure connection. SafeWay S30 and S51 series threaded couplings are 100% leak-tested and completely field serviceable with seal repair kits.

  • S30 Series is a special purpose, double shut-off threaded connection coupling with a sleeve locking mechanism that mates the coupling halves and allows connection under operating pressures up to 10,000 psi.
  • S51 Series is a heavy-duty, double shut-off threaded coupling with a minimum spill design. This series offers compatibility with most industrial fluids and is designed for applications with operating pressures up to 3,000 psi. Wing or hex nut locking style.
