Flat-Face Quick-Disconnect Coupling

Non-spill, robust and safe for any application
DBG series, DN 4 to 65
More than 500,000 coupling cycles
Most cost-effective of plain, low-alloy stainless steel

The flat-face sealing design enables non-spill disconnect and inclusion-free coupling operations.

• Temperatures ranging between -80°C and +325°C
• Single-hand operation
• Non-spill disconnection: No environmental damage or hazards to persons due to spilled liquid or exiting gas
