Reznor 98698 Pilot Tube

Maintain precise combustion control with the Reznor 98698 Pilot Tube, a 1/8-inch outer diameter (OD) aluminum component engineered for gas-fired heating units. Measuring 18 inches in length, this OEM Reznor replacement part is vital for delivering a consistent gas supply from the valve to the pilot burner assembly. Its high-temperature resistant construction ensures the pilot tubing remains structurally sound under the thermal stress of constant operation, preventing the common "lazy flame" or pilot failure issues often seen in older Reznor duct furnaces. This specific line is compatible with various Reznor series, including the EEDU and HEEDU models, as well as F-series units. For a complete installation, note that this tube typically interfaces with a 1/8" male compression nut, which should be inspected for thread integrity during service. Utilizing genuine Reznor 98698 components ensures proper flame impingement on the thermocouple or flame sensor, maintaining safe and efficient burner ignition across all HVAC heating systems.

• Universal Reznor Compatibility: Designed to fit a wide range of Reznor equipment including F-100 through F-400 series and HEEDU duct furnaces.
• Exact 18-Inch Length: Provides sufficient reach for standard pilot assemblies while allowing for precise field bending without kinking.
• Durable Aluminum Alloy: Built to withstand the high-ambient heat of the burner compartment without oxidizing or clogging.
• Stable Pilot Flame: Ensures a crisp, blue flame for reliable thermocouple activation and reduced nuisance lockouts.

Is the 98698 tube pre-flared or threaded?
This is a standard 1/8" OD pilot line that is typically used with compression fittings. Technicians should verify the condition of the existing 1/8" Pilot Male Compression Nut (part number 97572) during replacement.

What causes this pilot tube to fail?
Most failures are due to carbon buildup (soot) clogging the orifice end or physical damage/kinking during previous maintenance. If the pilot flame is yellow or lifting, check the tube for internal restrictions.

Can this be used for both Natural Gas and Propane units?
Yes, as long as the pilot burner orifice is correctly sized for the specific fuel type, the Reznor 98698 is rated for use with both NG and LP gas-fired equipment.
