Thread-to-connect design eliminates premature wear or brinelling associated with locking ball designs subjected to high impulse pressures. The internal valve allows connection and disconnection with high residual pressures. Flat face design avoids loss of hydraulic fluid during connection/ disconnection. Flat face design is easly to clean, limiting contamination into the circuit. - High working pressures: 40-60 MPa/5800-8700 psi range based on size- Thread coupling system eliminates brinelling, premature leakage- Connect/disconnect under residual pressure up to 25 MPa/3625 psi- Valve limits fluid movement during connection avoiding damage to other elements of circuit- Low connection force required- Excavators w/auxiliary line for attachments: thumbs, grapples, hammers, and compactors/hopaks- Oil Field, well head drives, porta-power- Cranes, drilling machines, all large equipment needing junction points in circuit- All construction equipment applications with higher pressure requirements or issues of  connecting/ disconnecting tool attachments under residual pressure- Eliminates brinelling, reduces leakage- Save time changing toolsINTERCHANGESTUCCHI FLAT FACE VEP SERIES, VOSWINKEL FT SERIESPERFORMANCETEMPERATURE RANGE-20oC+120oC/-4oF+250oFWith standard seals: Buna-N(Nitrile)-20oC+175oC/-4oF+347oFWith standard seals: VitonOn request seals: Viton, Neoprene, EPDM or other seals.Art.
