A-Premium A/C Discharge Line Hose Assembly for Chevrolet & GMC 1st-Design — Direct-Fit High-Pressure

A-Premium A/C Discharge Line Hose Assembly delivers a direct-fit high-pressure line that reconnects the compressor to the condenser for select Chevrolet, GMC, Buick and Saturn 1st-design models.

If your vehicle's air conditioning isn't cooling properly or you've identified a leaking high-pressure hose, this A-Premium discharge line is designed as a factory-style replacement. Built to match original routing and connections for first-design applications, the hose restores the sealed path between compressor and condenser. It includes reference numbers for quick cross-checking and comes with a one-year unlimited-mile guarantee, giving you confidence when swapping out a worn or damaged line.

Which vehicles will this discharge line fit?

This hose is compatible only with first-design versions of specific models. It fits Chevrolet Traverse 2009–2012 (excluding second-design Traverse units), GMC Acadia 2007–2012, Buick Enclave 2008–2012, and Saturn Outlook 2007–2010 when the vehicle has the first-design A/C routing.

• Chevrolet Traverse: 2009, 2010–2012 (1st-design only)
• GMC Acadia: 2007–2012 (1st-design only)
• Buick Enclave: 2008–2012 (1st-design only)
• Saturn Outlook: 2007–2010 (1st-design only)

How do I confirm my vehicle uses the 1st-design hose?

Identify the hose routing and connector shapes under the hood and compare them with your old high-pressure line or vehicle service manual. Many fitment mismatches occur when owners assume interchangeability; verifying the design prevents returns and ensures proper sealing.

• Visually compare connector types and bends to the original hose
• Check OEM reference numbers: HA11109C, 15926077, 34-64264, 4812238, 56450
• Confirm model year and known 1st-design listing before ordering

What should I expect from installation and performance?

The A-Premium discharge hose replaces the high-pressure line between compressor and condenser and is shaped to follow original equipment routing. Installation typically involves removing the damaged hose, replacing O-rings, and torqueing fittings to factory specs for a leak-free connection.

• Direct-fit design mirrors factory routing for easier installation
• Designed to meet A/C system pressure demands without modification
• Replace O-rings and evacuate/recharge system per standard service procedures

Does this product come with a warranty or guarantee?

A-Premium includes a one-year unlimited-mileage guarantee on the A/C hose, covering manufacturing defects under normal use. This warranty supports confidence in the part’s fit and workmanship but does not replace proper installation or cover damage from improper service.

• One-year unlimited-mile guarantee from A-Premium
• Warranty covers manufacture-related defects, not installation errors
• Retain proof of purchase for warranty claims

Who is this for: This discharge line is targeted at do-it-yourselfers, independent mechanics, and fleet technicians working on first-design Chevrolet, GMC, Buick, or Saturn models who need an OEM-style replacement high-pressure hose. If you confirmed your vehicle’s A/C routing is the 1st-design configuration and you need to repair a leak or replace a damaged compressor-to-condenser line, this A-Premium assembly provides a like-for-like option with cross-reference numbers for fast verification.
