GPD 1321406 A/C Expansion Valve Thermal Expansion Valve

The GPD 1321406 is an aftermarket A/C expansion valve (thermal expansion valve / TXV) designed as a direct-fit replacement for the 2002–2003 Mercedes-Benz SLK32 AMG. Manufactured by Global Parts Distributors (GPD), this component is engineered to restore proper refrigerant flow and cooling performance to the vehicle's air conditioning system.

The expansion valve regulates the flow of refrigerant into the evaporator core, controlling the pressure drop that allows the refrigerant to absorb heat and cool the cabin. A failed or restricted expansion valve commonly results in poor A/C performance, inconsistent cooling, or a system that blows warm air.

Key Features:

• Direct-fit replacement designed to meet or exceed OE fit, form, and function
• Engineered specifically for the 2002–2003 Mercedes-Benz SLK32 AMG (R170 chassis)
• Manufactured by GPD (Global Parts Distributors), a leading aftermarket HVAC supplier
• Restores proper refrigerant metering and A/C system efficiency
• Designed for use with R-134a refrigerant systems

GPD products are built to meet or exceed original equipment standards, making the 1321406 a reliable, cost-effective solution for restoring full air conditioning functionality to the SLK32 AMG.
