Stainless Steel Dry Break Coupling for Hose Flow Control

A tank unit & a hose unit of stainless steel dry break coupling

Stainless steel dry break coupling full set

Stainless steel dry break coupling is composed of tank unit and hose unit. It provides an automatic mechanism to seal off both the hose and the fixed pipe end. It is used to control the flow of low-viscous liquid, such as coolants by controlling the opening and closing of the dry break coupling. Besides, it can also help to extract liquid samples and conduct pressure test.

Stainless steel dry break coupling has very robust structure, which makes it have excellent damage & wear resistant performance and their surface are hardened with suitable metal coatings such as zinc or nickel, which makes them have excellent corrosion resistant performance.

Characteristics

  • Quick coupling/de-coupling without significant loss of media
  • Reduce the possibility of human error in transfer operations
  • Couplings reduce spillage to virtually zero
  • Ease of handling
  • Prevent cross-contamination between products
  • Safety of human health and the environment

Operation Principle

Connect and disconnect tank unit & hose unit

Stainless steel dry break coupling operation principle

Push the tank unit and hose unit together, and turn the hose unit 105° clockwise to make them coupled and form a full flow channel for liquid transfer.

If you want to disconnect them, simply turn 105° counterclockwise and pull them away to release them without spillage.

Note:

  • Tank unit and hose unit are generally used together, but if you need a separate tank unit or hose unit, we can also provide you with one.
  • You can operate stainless steel dry break coupling refer to the following video.
