Mars 068u4901 Ice Machine Expansion Kit 3/8x1/2 Odf

Product Description

The MARS 068u4901 is a universal thermostatic expansion valve (TXV) kit designed for ice machine refrigeration systems with an internal equalizer configuration. It features 3/8 inch x 1/2 inch ODF connections and serves as the primary metering device controlling refrigerant flow into the evaporator. The internal equalizer design makes it well suited for systems with low-to-moderate pressure drop across the evaporator. Licensed HVAC-R technicians performing ice machine service or refrigerant system repairs are the primary installers of this component.

This expansion kit is intended for use in commercial and light-commercial ice machine applications where a universal TXV replacement is required. The 3/8 inch inlet and 1/2 inch ODF outlet sizing covers a broad range of common ice machine evaporator circuits. It is appropriate for service work on self-contained ice machines and remote condensing unit ice systems where the original TXV has failed or is being replaced as part of a refrigeration system repair.

Key Features

• Universal fit design for ice machine TXV replacement applications
• 3/8 inch x 1/2 inch ODF connections for broad compatibility
• Internal equalizer construction suited for low-to-moderate evaporator pressure drop systems
• ODF (outside diameter flare) fittings compatible with standard refrigeration copper tubing

Compatibility

Designed as a universal OEM-style replacement TXV kit for ice machine refrigeration systems using 3/8 inch x 1/2 inch ODF connections with an internal equalizer configuration.

Installation Notes

Installation should be performed by an EPA 608-certified HVAC-R technician. Recover all refrigerant from the system before removing the existing TXV, in accordance with EPA Section 608 requirements. Ensure the system is fully depressurized and isolated before brazing or making mechanical connections. Verify refrigerant type and system operating pressures are compatible with this valve before returning the system to service.
