Eaton FD35 — 10,000 psi Arc Latch Hydraulic Quick Coupler

The Eaton FD35 — 10,000 psi Arc Latch Hydraulic Quick Coupler is a hydraulic quick-disconnect coupling from Eaton's Aeroquip range. Heavy-duty 10,000 psi quick coupler with Arc Latch™ design — greater latch surface contact area for long service life in rugged high-pressure hydraulic applications.

Working pressure to 700 bar (10153 psi) at the smallest body size, with minimum burst pressure of 2800 bar. Arc Latch connection — valved (self-sealing poppet) variant.

Construction & features

• Connection method: Arc Latch
• Valving: Valved (Self-sealing Poppet)
• Arc Latch™ design with extended latch contact surface
• Safety sleeve lock prevents accidental disconnection
• Heavy-duty back-up ring prevents O-ring extrusion at 10,000 psi
• Heat-treated and plated steel for wear and corrosion resistance
• Self-sealing poppet valves for excellent high- and low-pressure sealing
• 125 psi bleed-valve variant available (FD-1044) — relieves disconnected pressure build-up
• Interchanges with: UP10P-37F, UP10S-37F (Stucchi)
