clean break (up to 650 bar / 10,000 psi)

Depending on the application, clean-break couplings are also referred to as dry couplings or drybreak couplings. They connect with virtually no air entrapment or fluid ingress; when disconnected, only a minimal, physically unavoidable leakage occurs in the form of a film on the components.

They consist of a coupling and a nipple / adaptor and seal the ends of the lines drip-free using low-leakage valve technology. This is essential, particularly in safety-critical sectors such as medical technology and the chemical and pharmaceutical industries. Furthermore, clean-break couplings enable quick, safe, splash-free and leak-free connection and disconnection – in some cases even under residual pressure. Depending on the application, they convey media such as compressed air, acids, gases, hydraulic oils or cooling water. The designs vary in terms of connection mechanism, material and pressure range (low, medium, high pressure) and are available as flat-face, ball-face or sterilisable (SIP) variants, depending on hygiene and safety requirements.
