A spring-free flow path allows more chemicals to pass through these tube couplings at lower line pressures than other quick-disconnect couplings.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated.
