Overview

This Nissens A/C expansion valve, part number 9991050, is a block-style thermal expansion valve for R134 refrigerant systems. It is built to OE matching standards for pressure control, tightness, opening behavior, set-point accuracy, and internal finish.

Compatible With Nissan and INFINITI applications, this valve is a fitment-based replacement for a wide range of late-model HVAC systems. The 9991050 part number is also referenced in cross applications such as 922006GU0A and EX10698C.

Key Features

• Aluminum block-style expansion valve for R134 A/C systems
• Built to precise OE matching standards
• Validated for pressure performance, tightness, and opening control
• O-rings included for applicable installations
• Mounting bolts included when applicable

Detailed Description

Nissens 9991050 is an A/C expansion valve used to regulate refrigerant flow through the HVAC system. Its aluminum construction and block design support consistent refrigerant metering in systems that use R134, while Nissens testing focuses on pressure performance, sealing, opening characteristics, set-point setting, and internal finish. This part number is a direct fitment-based option for Nissan Altima, Rogue, Sentra, Murano, Frontier, TITAN, Maxima, 370Z, Z, Armada, and INFINITI QX50, QX55, and QX80 applications listed below.

This part cross-references Monroe Shocks & Struts (e.g., 922006GU0A, EX10698C) for the same application.

What It Is Used For

• Uneven cabin cooling caused by incorrect refrigerant metering
• Restricted A/C performance from a worn or sticking valve
• HVAC pressure control issues in the refrigerant circuit
• Sealing concerns related to aging valve components
• Replacement during A/C service on listed Nissan and INFINITI models

Installation Notes

Verify refrigerant type, valve style, and system configuration before installation. Use the listed fitment data to confirm the correct application for your Nissan or INFINITI vehicle, including model year and position notes where shown. Replace seals as required by the service procedure and follow proper evacuation and recharge practices after installation.

Quality Assurance

Nissens manufactures this expansion valve to strict OE matching standards and validates it for pressure performance, tightness, opening behavior, set-point setting, and internal finish. O-rings and mounting bolts are supplied whenever applicable.
