Diversitech m-3g Glass Refill for M-3

Product Description

The DIVERSITECH m-3g is a replacement glass refill designed for use with the M-3 moisture indicator. Moisture indicators are small sight glass assemblies installed in refrigerant lines to allow HVAC technicians to visually monitor system moisture levels and refrigerant flow. When the sight glass element in the M-3 indicator becomes damaged, fouled, or discolored beyond reliable use, the m-3g provides a direct replacement glass element to restore accurate visual indication without replacing the entire indicator body. Licensed refrigeration and HVAC technicians typically handle this type of component service during system maintenance or repair.

The m-3g glass refill is intended for use specifically with the DiversiTech M-3 moisture indicator. It is suited for residential and light commercial refrigeration and air conditioning systems where inline moisture indication is part of the service and diagnostic workflow. Technicians performing refrigerant system service who find the M-3 indicator glass element compromised can swap in this refill rather than replacing the full assembly.

Key Features

• Direct replacement glass element for the M-3 moisture indicator
• Restores visual moisture and flow indication without full indicator replacement
• Designed for compatibility with the existing M-3 indicator body
• Supports cost-effective field repair during refrigerant system service

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Before servicing any moisture indicator or sight glass assembly, recover refrigerant and depressurize the system in accordance with EPA Section 608 regulations and applicable local codes. Follow the M-3 indicator manufacturer instructions for glass element replacement to ensure a leak-free reassembly.
