Eaton FD49 — NFPA T3.20.15 HTMA Interchange Hydraulic Tool Coupler

The Eaton FD49 — NFPA T3.20.15 HTMA Interchange Hydraulic Tool Coupler is a hydraulic quick-disconnect coupling from Eaton's Aeroquip range. NFPA T3.20.15 HTMA-interchange coupler developed with the Hydraulic Tool Manufacturers Association — for hydraulic impact tools. Eaton Twin-Guard™ sealing prevents weepage and allows connect/disconnect against pressure to 500 psi.

Working pressure to 207 bar (3002 psi) at the smallest body size, with minimum burst pressure of 621 bar. Push-to-Connect connection — flush face (no-spill) variant.
