Mitsubishi Electric e22151667 Liquid Line Union

Product Description

The MITSUBISHI ELECTRIC e22151667 is a liquid line union fitting designed for use in refrigerant piping systems. This component creates a secure, leak-resistant mechanical connection between two sections of liquid line tubing. It is typically installed by HVAC technicians during new system commissioning or when servicing split-system and multi-split refrigerant circuits. The union design allows for disconnection and reconnection of refrigerant lines without cutting or flaring new tubing, making it a practical service fitting for field repairs and replacements.

This liquid line union is suited for residential and light commercial HVAC applications where refrigerant liquid line connections must be made or broken for service access. It is used in conjunction with MITSUBISHI ELECTRIC mini-split and multi-zone systems that require properly fitted refrigerant piping unions at service points or lineset transitions. Installation is performed by licensed HVAC technicians following applicable refrigerant handling and piping standards.

Key Features

• Union design allows disconnection and reconnection of liquid line sections without cutting tubing
• Engineered as an OEM-specified fitting for MITSUBISHI ELECTRIC refrigerant systems
• Liquid line rated construction suitable for high-pressure refrigerant service
• Supports clean, leak-resistant field connections during service or installation

Compatibility

Designed as an OEM-style liquid line union replacement for MITSUBISHI ELECTRIC split-system and multi-zone HVAC equipment.

Installation Notes

Installation must be performed by a licensed HVAC technician with EPA Section 608 certification for refrigerant handling. Recover all system refrigerant and verify the system is depressurized before disconnecting any refrigerant line fittings. Follow the equipment manufacturer's service documentation and applicable mechanical codes when making refrigerant piping connections. After reconnection, leak-test all joints before recharging the system.
