gpd 4812378 A/C Refrigerant Manifold Hose Line

The gpd 4812378 is a direct-fit A/C refrigerant manifold hose line designed to restore proper air conditioning system function. Manifold hose assemblies combine suction and discharge lines into a single unit: the suction (low-side) hose runs from the compressor to the evaporator, the discharge (high-side) hose runs from the compressor to the condenser, and the liquid line connects the condenser to the evaporator. Replacing a worn or leaking manifold line with a properly engineered replacement helps maintain system pressure, refrigerant flow, and cooling performance.

Key Features:

• Designed to meet or exceed OE fit, form, and function
• Direct-fit replacement for straightforward installation
• Application-specific design for precise compatibility
• Durability tested on every new design

This gpd manifold hose line is built to deliver reliable, long-lasting performance. Fits select 2004–2005 Chevrolet, Cadillac, and GMC models.
