Mitsubishi Electric CMY-R160-J1 Wye Joint Pipe Adapter

Product Description

The MITSUBISHI ELECTRIC CMY-R160-J1 is a wye joint pipe adapter used in multi-zone mini-split refrigerant piping systems. This fitting splits a single refrigerant line set into two branch runs, transitioning from a 3/8-inch to 3/4-inch main line down to two 3/8-inch to 5/8-inch branch connections. It is a factory-engineered component designed for use with Mitsubishi Electric multi-split systems where one outdoor unit serves multiple indoor air handlers. Licensed HVAC technicians install this adapter during new system installations or when reconfiguring existing multi-zone refrigerant piping layouts.

This adapter is used in residential and light commercial multi-zone ductless mini-split applications. It fits into the refrigerant distribution piping network between the outdoor condensing unit and multiple indoor evaporator units. Proper sizing of the branch connections is critical to maintaining correct refrigerant flow and system efficiency. Installation typically occurs during the rough-in or commissioning phase of a multi-split system build-out.

Key Features

• Wye configuration splits one main refrigerant line into two branch circuits
• Main line sizing: 3/8 inches to 3/4 inches
• Branch line sizing: 3/8 inches to 5/8 inches
• Factory-engineered OEM component for Mitsubishi Electric multi-split systems
• Supports proper refrigerant distribution across multiple indoor units

Compatibility

Designed as an OEM-style wye joint pipe adapter for Mitsubishi Electric multi-zone mini-split refrigerant piping systems requiring a main line transition of 3/8 inches to 3/4 inches splitting to dual branch runs of 3/8 inches to 5/8 inches.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 regulations. Recover all refrigerant and confirm the system is fully depressurized before disconnecting or modifying any refrigerant piping. Braze or flare connections according to the manufacturer specifications and applicable mechanical codes. Do not mix pipe adapter sizes outside of the intended branch configuration, as improper sizing will affect refrigerant charge balance and system performance.
