Goodman 158555J Liquid Stop Valve Assembly

Product Description

The Goodman 158555J is a liquid stop valve assembly designed for use in refrigerant circuit applications. Stop valves of this type control or isolate refrigerant flow on the liquid line of a split-system HVAC unit, allowing technicians to service components without a full system evacuation. The assembly provides a positive shutoff point on the high-side liquid line and is built to withstand the pressures typical of modern refrigerant systems. HVAC technicians working on Goodman equipment will recognize this as an OEM replacement part engineered to factory specifications.

This valve assembly is installed on the liquid refrigerant line in split-system air conditioning and heat pump equipment. It is suited for residential and light commercial applications where an OEM-style replacement is required to restore proper system isolation capability. When the original valve shows signs of leakage, corrosion, or mechanical failure, replacing it with the factory-specified 158555J restores the integrity of the refrigerant circuit and supports safe, code-compliant service work going forward.

Key Features

• OEM replacement valve assembly sourced directly from Goodman manufacturing specifications
• Designed for liquid refrigerant line service and isolation
• Provides positive shutoff to allow component-level servicing without full system recovery
• Built to withstand high-side refrigerant line operating pressures

Compatibility

Designed as an OEM-style replacement liquid stop valve assembly for Goodman split-system air conditioning and heat pump units. Verify compatibility against the original equipment model number and service documentation before installation.

Installation Notes

Installation should be performed by an EPA 608-certified HVAC technician. Recover all refrigerant from the system in accordance with EPA regulations and relevant local codes before removing the existing valve assembly. Ensure all refrigerant pressure is relieved from the liquid line before beginning disassembly. Follow the equipment manufacturer's service documentation for torque and connection procedures specific to the unit being serviced.
