Lennox 44H12 Tubing

The Lennox 44H12 Pressure Switch Tubing is a critical 19-inch OEM replacement part designed for precise pressure monitoring in commercial HVAC systems and residential furnaces. With a 3/16-inch ID and 5/16-inch OD, this specialized tubing connects the inducer motor or collector box to the furnace pressure switch, ensuring the control board receives accurate pneumatic signals for safe ignition sequences. Constructed from high-grade, flexible elastomers, the 44H12 is engineered to withstand the thermal stress and chemical exposure typical of Lennox 80MGF series units and high-efficiency condensing systems.

For technicians troubleshooting "Pressure Switch Open" fault codes, replacing worn or brittle lines with this genuine Lennox replacement part is essential to prevent system lockouts and short-cycling. The 19-inch length provides ample slack for proper routing around the inducer housing, minimizing the risk of kinking or heat-related degradation. By maintaining a clear, airtight connection between the sensing ports, this tubing facilitates optimal HVAC system performance and safety. Compatible with multiple legacy Lennox, Armstrong, and Ducane models, it serves as a direct substitute for part numbers LB-51467DE and 60G10.

Key Benefits
  • Precise Signal Transmission: Ensures the pressure switch accurately detects the vacuum or pressure required to engage the burner.
  • OEM Compatibility: Guaranteed fit for Lennox 80MGF units and various condensing furnaces, replacing outdated or brittle factory lines.
  • Durable Material Construction: Resists cracking, moisture accumulation, and high-temperature environments within the furnace cabinet.
  • Ease of Installation: Flexible 3/16" ID tubing allows for clean routing in confined spaces without restricting airflow to the switch.
Common Questions
  • Is this tubing compatible with multi-stage condensing furnaces? Yes, the 44H12 is frequently used in condensing systems that utilize two hoses to monitor pressure differentials between the burner enclosure and collector box.
  • Will this fix a "Pressure Switch Stuck Open" error code? If the error is caused by a cracked, clogged, or brittle hose leaking air, replacing it with this new tubing will resolve the issue.
  • What does the 19-inch length cover? This length is standard for most Lennox cabinet configurations, allowing enough slack to avoid points of high heat or mechanical vibration.
