Heil Quaker ICP 1003687 Tube

The Heil Quaker ICP 1003687 Pressure Switch Tube is a critical OEM replacement part designed for precise vacuum signal transmission between the inducer housing and the pressure switch. Measuring 1/8" ID x 24" length, this high-temp silicone tubing is engineered to withstand the rigorous thermal cycles found in modern condensing furnaces and packaged units. Maintaining a clear, airtight connection is non-negotiable for system safety; a cracked or brittle hose often leads to pressure switch stuck open errors, preventing ignition and causing immediate system lockout. This genuine ICP replacement tubing ensures a perfect friction fit on specialized 1/8" ports, eliminating the risk of vacuum leaks that commonly occur with lower-grade universal hoses. When performing HVAC preventative maintenance, replacing a weathered 1003687 tube sensor is a standard best practice to ensure the draft inducer motor correctly signals the control board. This part replaces several legacy numbers, including 1071343S, 1000782, and 105580, providing wide compatibility across Heil, Tempstar, and Comfortmaker equipment.

Key Benefits:

• Genuine ICP OEM Component: Ensures exact fit and wall thickness for 1/8-inch furnace pressure switch ports.
• High-Temperature Resistance: Constructed from professional-grade silicone to prevent hardening and cracking near the heat exchanger.
• Optimized Length: The 24-inch hose provides ample reach for custom routing, allowing for the creation of proper moisture traps in high-efficiency systems.
• Safety Restoration: Resolves furnace ignition failure and frequent short-cycling caused by degraded sensor lines.

Common Questions:

• Why is my furnace pressure switch not closing? Often, a clogged or cracked suction tube prevents the inducer's negative pressure from reaching the switch diaphragm. Inspect this 1/8" tubing for blockages or signs of heat damage.
• Can I use standard vinyl tubing instead? No. Standard vinyl cannot handle the operating temperatures of an HVAC burner compartment and will collapse or melt, leading to unsafe operating conditions and system failure.
• Does this tube fit multiple brands? Yes, the ICP 1003687 is the direct replacement for most Heil Quaker, Arcoaire, and Day & Night furnaces requiring 1/8" ID pressure hoses.
