Exhaust gas recirc Volvo 140 (1974) (B20F MRA)

The group includes copper washers, nipples and union nuts for the connections, hose and hose clamps for the routing, plus nuts, rubber cap and cone that seal and protect exposed points. Since the fit follows the specific B20F setup, the chassis number and model year should be checked before ordering – small differences in nipple dimension and hose thickness determine whether the joint stays tight. When refurbishing, it is practical to replace the copper washers and clamps at the same time as the hose, so the entire joint becomes clean and leak-free in one go.
