BOCK FKX40/755K Bus AC Compressor – Genuine New & Remanufactured 755cc 4-Cylinder Unit | R134a

OEM Verification: This Is a Documented BOCK Configuration

The FKX40/755K is not an aftermarket invention – it is a catalogue configuration of the BOCK FK(X) vehicle compressor family, verified against the official Danfoss-BOCK product data (BOCK identity FKX40/755 K). The 755K is the top displacement member of the FK(X)40 4-cylinder series, rated for air-conditioning duty with a documented configuration: R134a / R513A / R407C refrigerants, BOCKlub E55 oil, unpainted aluminium housing, suction and discharge valves with braze-free connections.

We supply the FKX40/755K as a genuine brand-new unit and as a professionally remanufactured unit. Every new unit carries the original BOCK nameplate – with the theoretical displacement (Vth 65.6 m³/h at 1450 rpm) and maximum pressure ratings (LP 19 bar / HP 28 bar) printed on the plate – together with the BOCK parts kit (mounting bolts and gaskets) as delivered from the factory.
