Eaton FD83 — Full-Flow Dual-Interlock Stainless Coupler (Electronics Cooling)

The Eaton FD83 — Full-Flow Dual-Interlock Stainless Coupler (Electronics Cooling) is a specialty quick-disconnect coupling from Eaton's Aeroquip range. Full-flow dual-interlock stainless steel coupler with identical halves — engineered for electronics liquid cooling and thermal-management systems. Dual interlock prevents accidental opening when disconnected and prevents disconnect with valves open.

Working pressure to 10 bar (145 psi) at the smallest body size, with minimum burst pressure of 20 bar. Push-Pull Ball Latch connection — valved (self-sealing poppet) variant.
