DESO Stems

Swagelok QC series quick connects are engineered for applications where speed and ease of connection are critical. The DESO (Double-End Shut-Off) configuration ensures that the flow is restricted when the stem is uncoupled, significantly reducing fluid loss and environmental contamination.

Safety and Compatibility

• Selection of the correct product requires consideration of the total system design to ensure safe, trouble-free performance.
• Do not mix or interchange Swagelok products or components with those of other manufacturers to maintain system integrity and safety.
