A-Premium A/C Discharge Line Hose Assembly for Chevrolet & GMC — First-Design Direct-Fit, OEM-Style Sealing

A-Premium A/C Discharge Line Hose Assembly is a direct-fit high-pressure hose that connects the compressor to the condenser for certain 1st-design Chevrolet, GMC, Buick, and Saturn models.

This replacement discharge line restores proper refrigerant flow and pressure routing in compatible factory air-conditioning systems. Built to meet OEM-style dimensions and sealing points, the hose is supplied ready to install and includes reference numbers for cross-checking fitment. Before ordering, confirm your vehicle uses the 1st-design discharge configuration, since this assembly is not compatible with the 2nd-design layout (with the exception noted below).

How does this discharge line improve A/C performance?

Replacing a worn or leaking high-pressure discharge hose eliminates loss points that reduce system efficiency. With correct routing and secure fittings, the new hose helps maintain refrigerant charge and prevents pressure fluctuations that can impair cooling.

• Restores factory routing from compressor to condenser
• Reduces the chance of refrigerant leaks and pressure loss
• Helps the A/C system reach proper operating pressure more reliably
• Designed to match OEM connection points for a sealed fit

What should I check to confirm this is the right part for my car?

Match the hose layout and connection locations with your vehicle’s existing discharge line to ensure you have the first-design configuration. Use the provided part reference numbers and model-year compatibility to cross-check with factory or aftermarket catalogs.

• Visually compare hose routing and fittings to your current assembly
• Confirm vehicle model and year fall within the listed ranges
• Check part numbers: HA11109C, 15926077, 34-64264, etc.
• Note: 2009 Chevrolet Traverse may have a different nuance—verify design version

What warranty and quality assurances come with this A/C hose?

A-Premium backs this hose with a one-year, unlimited-mileage guarantee against manufacturing defects and workmanship issues. The hose is produced to meet common OEM dimensions and sealing standards to help ensure a dependable replacement experience.

• One-year unlimited-mileage warranty from A-Premium
• Manufactured to match common OEM fit and sealing points
• Shipped as a ready-to-install assembly for faster replacement

Who is this for: This A-Premium discharge line is intended for owners, DIY mechanics, and repair shops working on first-design Chevrolet Traverse, GMC Acadia, Buick Enclave, or Saturn Outlook models listed above. Choose this assembly when the existing high-pressure hose shows signs of leakage, visible damage, or if A/C pressure testing indicates a refrigerant loss point between the compressor and condenser. If your vehicle uses a second-design discharge configuration, this part will not fit—confirm design type before purchase to avoid returns.
