Lennox 71L17 Tubing

Lennox 71L17 Tubing

The Lennox 71L17 Tubing is a critical OEM replacement part designed for precise HVAC pressure switch integration. Engineered to maintain the pneumatic link between the combustion air inducer and the pressure switch, this high-grade silicone tubing ensures accurate monitoring of negative pressure within the collector box or inducer housing. For veteran technicians, this 71L17 pressure switch hose is the standard for resolving "Pressure Switch Open" or "Stuck Closed" fault codes (often alerts 223 or 224 in Lennox communicating systems) caused by cracked, brittle, or clogged lines.

This 3-inch Lennox furnace tubing is built to withstand high-temperature environments without collapsing, providing a reliable air signal to the diaphragm. It is specifically compatible with a wide range of Lennox GH19P series furnaces, including the GH19P-100-1 and GH19P-125-1 models. Utilizing genuine Lennox parts like the 71L17 ensures the inducer limit circuit operates within factory-specified inches of water column (w.c.), preventing premature system lockouts and maintaining the integrity of the heat exchanger safety loop.

Key Benefits
  • Precise Pressure Response: High-quality silicone construction prevents kinking and maintains a clear signal for pressure switch calibration.
  • Exact OEM Fit: Pre-sized at 3 inches for the Lennox 71L17 specification, eliminating the need for field modifications on GH19P models.
  • Enhanced Durability: Heat-resistant material prevents the hardening and cracking common in generic aftermarket vinyl pressure switch tubing.
  • System Reliability: Critical for clearing furnace alert codes related to combustion air inducer performance and flue blockages.
Common Questions
  • Can I use standard vacuum hose instead of the 71L17? While standard hosing might fit, the 71L17 is specifically rated for the thermal demands and precise internal diameters required by Lennox furnace safety circuits to prevent false trips.
  • Does this tubing include the plastic connectors? This SKU specifically covers the pressure switch tubing; if your barbed connectors or inducer orifice ports are damaged, they must be sourced separately.
  • How do I check if this tubing is the cause of my "Switch Open" code? Inspect for moisture/condensate buildup, cracks at the connection points, or internal obstructions that disrupt the vacuum signal to the pressure switch.
