🛠️ HVAC Depot Pro Tip

The 10M23 / 103881-01 is a 3/8-inch liquid line service valve. Do not confuse it with the larger suction-line service valve that may be installed on the same condenser or heat pump.

Before ordering, verify:

  • Cat # 10M23
  • Part # 103881-01
  • 3/8-inch line size
  • Liquid line application
  • Existing valve configuration
  • Connection type
  • Outdoor unit model number
  • Equipment serial number
  • Refrigerant requirements

Service valves may look very similar externally, so always match the OEM part number and equipment model rather than relying only on line size.

Equipment / Model Compatibility

The Lennox 10M23 / 103881-01 is used with select Lennox outdoor HVAC equipment, including compatible:

  • Lennox air conditioners
  • Lennox heat pumps
  • Outdoor condensing units
  • Central air conditioning systems
  • Select 13ACX Series equipment
  • Select XC13 Series equipment
  • Other Lennox systems specifically calling for 103881-01

Always verify the complete equipment model and serial number before ordering.
