About this item

  • 【Package Include】1PCS 3/4" Female thread check valve.
  • 【Solid Brass】The entire body of this check valve is made of solid brass, which is strong and not easily corroded, suitable for long time use. Can work normally under 232PSI pressure. No cheap and flimsy aluminum or plastic material.
  • 【Heavy & Thick】The port of the premium forged brass check valve is carefully designed with precision threads, which is easy to install and connect. Large-caliber connection means higher working efficiency, greater flow, and compact and reliable valve body structure.
  • 【Great Tool】The non-return valve are respectively for tube connecting, mainly used for the one-way flow of the medium in the pipeline, which only allows the medium to flow in one direction to prevent the medium from back-flow. Mark the direction of the liquid inlet, which is convenient to use and effectively prevents the liquid from flowing back.
  • 【Widely Used】The large-caliber, large-flow check valve can be used in fluid systems to prevent fluid back-flow, or in pneumatic systems to prevent compressed air back-flow, reducing accidents and ensuring normal work. It is widely used in water purifiers, solar energy, gas water heaters, faucets, etc.

I could not get the fittings tight enough to prevent leaking. One side bottomed out against the inside flange while hand tightening. The other side bottomed out on the male pipe fitting. Both sides leaked.
