A-Premium A/C Discharge Line Hose Assembly for Nissan 4.0L V6 — Direct-Fit, Four-Layer Construction

A-Premium's A/C discharge line hose assembly replaces the high-pressure line from compressor to condenser for Nissan 4.0L V6 models, restoring proper refrigerant flow and system integrity.

If your Frontier, Pathfinder, or Xterra with the 4.0L V6 is showing reduced cooling performance, visible hose wear, or oil residue near the high-pressure line, this A-Premium discharge hose is engineered to be a direct-fit replacement. Built with a four-layer construction to resist collapse and extreme temperatures, the hose matches OEM routing and reference numbers for quick installation and reliable operation.

Which Nissan models and years does this discharge line fit?

This hose is designed for specific Nissan 4.0L V6 applications. It fits the Frontier, Pathfinder, and Xterra model years where factory routing and connections match the listed part references.

• Frontier 2005–2019 V6 4.0L (DOHC; Petrol) and 2018–2019 Flex V6 4.0L.
• Pathfinder 2005–2007 V6 4.0L (DOHC; Petrol).
• Xterra 2005–2015 V6 4.0L (DOHC; Petrol).
• Crosschecks with reference numbers HA11203C, 34-64468, 3464468 for fit verification.

How is this discharge hose constructed and why does that matter?

Manufactured with a four-layer hose design, the assembly improves resistance to abrasion, internal collapse, and high thermal loads. That construction helps maintain refrigerant pressure and prevents premature failure under demanding driving conditions.

• Four-layer wall reduces risk of collapse under high pressure.
• Wider operating temperature range for hot engine bays or cold climates.
• Reinforced ends and fittings to preserve seals and prevent leaks.

Will this part restore my vehicle’s air conditioning performance?

Replacing a failing high-pressure discharge line can eliminate leaks and restore proper refrigerant containment, which often brings cooling performance back to expected levels. While the hose addresses the critical compressor-to-condenser path, full system recovery depends on refrigerant charge and condition of other components.

• Direct-fit replacement helps re-establish correct refrigerant pressure.
• Reduces risk of oil and refrigerant loss at worn hose connections.
• Works best when combined with leak testing and correct refrigerant recharge.

What warranty and buying assurances come with this A-Premium hose?

A-Premium provides a one-year unlimited-mileage guarantee on this A/C hose assembly, allowing confident use after installation. The brand also pools a broad selection of automotive replacement parts to simplify sourcing matching components if further repairs are needed.

• One-year unlimited-mileage warranty from A-Premium.
• Reference numbers listed for straightforward cross-referencing with OEM parts.
• Customer support options for fitment questions or replacement guidance.

Who is this for? This discharge line assembly is aimed at Nissan owners and independent mechanics who need a reliable, direct-fit high-pressure hose for Frontier, Pathfinder, or Xterra trucks with the 4.0L V6 engine. It’s especially useful if you’ve identified leaks, visible hose damage, or repeatedly low refrigerant pressure—prospects who want an OEM-style replacement with reinforced construction and a one-year parts guarantee.
