Nissens 9991010 A/C Expansion Valve

Overview

The Nissens 9991010 A/C expansion valve is a block-style refrigerant flow control component built for R134 systems. It is a direct-fit service part for select Hyundai and Kia applications, with aluminum construction and included O-rings and mounting bolts whenever applicable.

For Hyundai Elantra, Hyundai Elantra N, Kia Forte, Kia Forte5, and Hyundai Elantra GT applications, this valve is specified to OE-matching standards for pressure performance, tightness, opening behavior, set-point setting, and internal finish. The Nissens 9991010 is a practical replacement when restoring proper refrigerant metering in the HVAC system.

Key Features

• Block-style A/C expansion valve for R134 refrigerant systems
• Aluminum construction for HVAC service applications
• Includes O-rings and mounting bolts whenever applicable
• Manufactured and validated to OE-matching standards
• Part number 9991010 for direct identification

Detailed Description

The Nissens 9991010 regulates refrigerant flow into the evaporator, helping the HVAC system maintain correct pressure balance and cooling performance. Its block design and aluminum body make it a serviceable replacement for vehicles that use this style of expansion valve, including 2021-2025 Hyundai Elantra, 2022-2025 Hyundai Elantra N, 2019-2024 Kia Forte, 2020-2023 Kia Forte5, and 2019-2020 Hyundai Elantra GT. The part number 9991010 is also cross-referenced to 97626M6000 and UAC EX10686C for the same application.

Nissens states that these thermal expansion valves are tested for pressure performance, tightness, opening characteristics, set-point accuracy, and internal finish. That validation focus supports consistent refrigerant control in service work on Hyundai Elantra and Kia Forte HVAC systems.

What It Helps Address

• Inconsistent cabin cooling caused by poor refrigerant metering
• Restricted or unstable evaporator feed
• HVAC performance issues tied to valve wear or contamination
• Pressure control problems in the A/C circuit
• Service replacement needs for R134 expansion valve applications

Installation Notes

Verify refrigerant type, valve style, and system configuration before installation. Replace worn seals during service and confirm all sealing surfaces are clean and undamaged. Follow the vehicle service procedure for evacuation, recharge, and leak checking after installation.
