Carrier 1185498 Txv Kit R-410A 4 to 5 Ton

Product Description

The CARRIER 1185498 is a thermostatic expansion valve (TXV) kit designed for use with R-410A refrigerant systems rated at 4 to 5 ton nominal capacity. The TXV meters refrigerant flow into the evaporator coil, maintaining proper superheat and protecting the compressor from liquid slugging. This kit is built for residential and light commercial split-system cooling and heat pump applications. Licensed HVAC technicians install this component as part of a coil replacement or system retrofit where precise refrigerant metering is required.

This valve kit is suited for split-system air conditioning and heat pump installations operating on R-410A refrigerant at 4 to 5 ton nominal capacity. It is a factory-style replacement intended for systems where the original metering device must be updated or replaced. Installation typically occurs at the evaporator coil inlet, and the kit format provides the necessary components to complete the swap without sourcing additional hardware separately.

Key Features

• Rated for R-410A refrigerant — no refrigerant substitution required
• 4 to 5 ton nominal capacity range covers a wide range of residential and light commercial coil sizes
• Kit format includes components needed for a complete valve replacement
• OEM-style design supports proper superheat control and system efficiency
• Direct replacement format simplifies installation on compatible coil assemblies

Compatibility

Designed as an OEM-style replacement TXV kit for R-410A split-system air conditioning and heat pump evaporator coils in the 4 to 5 ton nominal capacity range.

Installation Notes

A licensed HVAC technician should perform TXV replacement in accordance with local mechanical codes and EPA Section 608 refrigerant handling regulations. Recover all refrigerant from the system before opening any refrigerant circuits. After installation, leak-test all connections, evacuate the system to proper vacuum, and verify superheat readings before returning the system to service. Do not reuse flare fittings or copper connections that show signs of wear or corrosion.
