• Block Compatibility Note: 6680018 fits the older FFI or FI stamped manifold block only — it is not compatible with the newer FFH or FH block. Check the stamp on the side of your manifold block before ordering. The male counterpart for this coupler is part 6679837
• Application: Female flat face hydraulic quick coupler cartridge — screws into the 4BD4FI manifold block to allow quick, no-spill connection of attachment hydraulic lines on applicable Bobcat skid steer loaders, compact track loaders, and compact excavators
• Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the female coupler leaks at the face seal, will not lock onto the male coupler, is difficult to connect or disconnect, or the internal poppet is worn or stuck open — a failed female coupler allows hydraulic fluid loss during attachment changes and reduces flow to powered attachments such as augers, breakers, and brush cutters on applicable Bobcat equipment.

Why Choose Broken Tractor:

• ✅ Block Identification Made Easy: The FFI/FI stamp is on the side of your manifold block — visible when the block is accessible. If your block is stamped FFI or FI, this is the correct female cartridge. Do not order this for an FFH or FH stamped block.
• ✅ Two Interchange Numbers Cross-Referenced: 6680018 interchanges with Kubota V0511-77150 and 84390118 — cross-platform compatibility confirmed across Bobcat and Kubota equipment using the same 4BD4FI block standard.
• ✅ Exceptional Multi-Generation Coverage: Fits over 60 Bobcat skid steer, compact track loader, and excavator models spanning more than two decades of production — one of the most widely used auxiliary hydraulic couplers in the Bobcat lineup.
• ✅ Fast Shipping from a U.S.-Based Team: In-stock and ready to ship from our U.S. warehouses.
