Description
This discharge line is designed without a switch service port or bracket. It includes the necessary fittings and two green O-rings (part numbers 24677 and 24678) for a secure, leak-free seal. The suction end features a P-nut fitting that is compatible with the original equipment setup. The unit does not include a muffler or switch, aligning with factory configurations for compatible BMW models.
