Eaton 5100 — Thread-to-Connect Brass Hydraulic Quick Coupler

The Eaton 5100 — Thread-to-Connect Brass Hydraulic Quick Coupler is a hydraulic quick-disconnect coupling from Eaton's Aeroquip range. Brass body thread-to-connect coupler with steel tubular valving — minimum air inclusion, low fluid loss, and connect-under-pressure capability to 500 psi. Wing or hex-nut configurations; the volume on-highway hydraulic wet-line coupler.

Working pressure to 207 bar (3002 psi) at the smallest body size, with minimum burst pressure of 600 bar. Thread-to-Connect connection — thread-to-connect variant.

Construction & features

• Connection method: Thread-to-Connect
• Valving: Thread-to-Connect
• Connect-under-pressure capability — couplings can be mated against trapped residual pressure
• Tubular valve construction — virtually no fluid loss during disconnection
• Low air inclusion during connection — maintains system performance
• Thread-together latch — vibration-resistant
• Connect-under-pressure capability to 500 psi
• Wing or hex-nut configurations
• Optional steel flange for bulkhead mounting
• NOT rated for continuous hydraulic impulse — for impulse, use FD86 or FD96
• Interchanges with: Parker 5100 / 6800 thread-to-connect, Faster TGI

Performance

• Maximum operating pressure: 207 bar (3002 psi) at the smallest size; derates with diameter
• Minimum burst pressure: 600 bar (8702 psi)
• Rated flow (largest size): up to 379 L/min
• Vacuum rating: 28 in./Hg
• Operating temperature range: -40°C to +100°C (varies by seal compound; specify in RFQ)

Applications

• On-highway hydraulic wet lines
• Dump and refuse vehicles
• Bulk liquid transfer
• Hydraulics and fluid transfer where vibration is high
• Bulkhead-mounted hose feed-through (with optional steel flange)

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.

Companion products

Indus also stocks the matching dust caps, dust plugs, and seal repair kits for this series — ask for them on the same RFQ. For hose assemblies terminated with this coupler, request a complete hose-end assembly quote and we will supply the assembly tested at 1.5× working pressure with witness-test certificate.
