Mating ends of the newer couplers are compatible with older style couplers, allowing old and new couplers to connect with each other. However, an FFI coupler will not function in an FFH block and vice versa.
The best way to identify which version block/coupler is installed is by looking for the manufacturers stamp: previous blocks and couplers have an FFI or FI, newer have an FFH or FH. The stamp is visible on the outside sleeve of male couplers. The stamp is also on the side of the block. Blocks that are connected inside the lift arm must be removed to see the stamp.
