Nissens 840004 A/C Hose Assembly Refrigerant Line

The Nissens 840004 is a direct-fit A/C hose assembly engineered to restore proper refrigerant flow in your vehicle's air conditioning system. Nissens is a globally recognized manufacturer of thermal and climate control components, and this hose assembly is built to meet or exceed OEM specifications for reliable, leak-free performance.

A/C hose assemblies are critical components that carry refrigerant between the major parts of the air conditioning system — such as the compressor, condenser, and evaporator. A worn, cracked, or leaking hose can cause refrigerant loss, reduced cooling efficiency, and potential compressor damage if left unaddressed.

Key Features:

• Designed to meet or exceed original equipment manufacturer (OEM) specifications
• Constructed with durable, heat- and pressure-resistant materials to withstand engine bay conditions
• Pre-assembled with fittings for a direct-fit, no-modification installation
• Resists refrigerant permeation to maintain system efficiency
• Compatible with common refrigerants including R-134a and R-1234yf (verify for specific application)
• Manufactured by Nissens, a trusted global supplier of automotive thermal components

This Nissens A/C hose assembly is an ideal replacement for a damaged or deteriorated OEM hose, helping restore your air conditioning system to proper operating condition with a straightforward installation.
