Polished 90 Degree Compressor Manifold Block for SD7B10 Sanden Compressors. Block features a #8 pressure port and a #10 suction port. This manifold is a handy addition to many aftermarket front accessory drive systems that use a SD7B10 compressor that is mounted with the ports oriented horizontally. We typically use straight service port hose end fittings when we use this manifold.
