Eaton FD45 — ISO 7241/1 Series B Non-Valved Hydraulic Quick Coupler

The Eaton FD45 — ISO 7241/1 Series B Non-Valved Hydraulic Quick Coupler is a hydraulic quick-disconnect coupling from Eaton's Aeroquip range. Non-valved variant of the FD45 ISO 7241/1 Series B coupler — straight-through bore for maximum flow with minimum pressure drop. Will not operate with valved coupling halves; intended for systems where line valving is upstream of the coupler.

Working pressure to 350 bar (5076 psi) at the smallest body size, with minimum burst pressure of 1260 bar. Push-Pull Ball Latch connection — non-valved variant.

Performance

• Maximum operating pressure: 350 bar (5076 psi) at the smallest size; derates with diameter
• Minimum burst pressure: 1260 bar (18275 psi)
• Rated flow (largest size): up to 189 L/min
• Vacuum rating: 28 in./Hg
• Operating temperature range: -40°C to +200°C (varies by seal compound; specify in RFQ)

Applications

• Bulk fluid transfer where line valves provide isolation
• Suction-side hydraulic returns
• Tool change-over where flow restriction is critical
• Lubrication and cooling line transfers

How to order

Confirm (a) the exact Eaton part number you require, or (b) the configuration parameters: coupling half (male / female / complete set / repair kit / dust cap), body size, port thread type and designation, seal compound, body material. Indus will quote ex-Eaton with full mill certification, NACE / ABS / Lloyd's options on request, and air-freight or sea-freight options to UAE / GCC. Standard lead time 14 days from order; in-stock items ship same week.
