The COUPLING BOSS FOR E2M28 PK1 is a replacement part made for the Edwards E2M28 rotary vane vacuum pump. This small metal part is a key piece of the drive coupling assembly. It connects the motor shaft to the pump shaft. Without a good coupling boss, the motor cannot turn the pump. If your pump is not pulling vacuum or making strange noises, this part may be worn out. Replace it to get your pump running again.
