GPD 1411403 Heavy-Duty A/C Accumulator Drier 3/8 Male Insert O-Ring

The GPD 1411403 is a heavy-duty aftermarket A/C accumulator/drier designed for demanding commercial and off-highway air conditioning systems. Featuring 3/8" male insert O-ring (MIO) inlet and outlet fittings, this drier is engineered to meet or exceed OEM specifications for heavy-duty applications including trucks, agricultural equipment, and construction machinery.

The accumulator/drier plays a critical role in the A/C system. Positioned on the low-pressure side between the evaporator and the compressor, it removes moisture and contaminants from refrigerant before it reaches the compressor — protecting system components and extending service life. Replacement is recommended any time the A/C system is opened for service.

Key Features:

• Heavy-duty construction for commercial and off-highway applications
• 3/8" male insert O-ring (MIO) inlet and outlet fittings
• Desiccant core absorbs moisture and filters debris from refrigerant circuit
• Protects the compressor from liquid slugging and contamination
• Manufactured by GPD (Global Parts Distributors), a leading aftermarket A/C brand
• Direct-fit replacement designed to meet or exceed OEM performance standards

GPD part number 1411403 is also commonly referenced as an HD Drier with 3/8 MIO porting. Always replace the accumulator/drier whenever the A/C system has been opened or when compressor failure has occurred to prevent contamination of the new components.
