Line Adapter Manifold - SD7 A/C Compressor

The Holley Line Adapter Manifold – SD7 A/C Compressor (HLY199-202) is a precision 2-port aluminum adapter designed for seamless integration with Sanden SD7 air conditioning compressors. This component bridges the gap between refrigerant line connections and the compressor inlet, making it essential for custom A/C system builds, retrofit installations, and OEM compressor replacements. Whether you're restoring a classic vehicle, upgrading an off-road cooling system, or servicing fleet equipment, this adapter ensures proper refrigerant flow and system integrity.

Manufactured from durable aluminum in natural (unpainted) finish, the Line Adapter Manifold delivers corrosion resistance and lightweight construction without sacrificing strength. The two-port configuration allows controlled routing of high-pressure and low-pressure refrigerant lines, reducing installation complexity and pressure drop across connection points. Holley's engineering ensures tight tolerances and reliable sealing, critical for maintaining system efficiency and preventing refrigerant leakage that can compromise cooling performance and damage the compressor over time.

Technicians and enthusiasts working with Sanden SD7 compressor platforms will find this adapter indispensable for custom air conditioning installations. Its compact footprint (3.15 x 2.05 x 3.35 inches) facilitates installation in tight engine compartments common to retrofit and hot rod builds. The natural aluminum finish pairs well with both show-quality and functional restorations. Proper installation requires alignment with your refrigerant line sizing and system pressure specifications to ensure optimal cooling and compressor longevity.
