Illinois 0036909 Repair Kit

The Illinois 0036909 Repair Kit is a comprehensive internal rebuild solution specifically engineered for Series G 6G-3/4 float and thermostatic steam traps. Designed for high-demand hydronic and steam heating systems, this kit includes a seamless copper float, thermostatic air vent element, stainless steel seat, and high-temperature cover gasket. This rebuild set is rated for systems operating up to 15 PSIG, ensuring precise condensate drainage and efficient air venting in modulating pressure applications. By replacing the internal bucket and thermostatic bypass, contractors can restore the 230 lbs/hr capacity of the 3/4" NPT 6G-15 trap without replacing the entire cast iron body. Utilizing genuine Illinois/Watts replacement parts ensures technical compatibility with existing horizontal in-line piping and maintains the specific sensitivity required to prevent steam loss into the return lines. This assembly is the industry standard for maintaining F&T steam traps in industrial and commercial boiler systems.

• Full Internal Rebuild: Includes the 6G-15 bucket, valve seat, and thermostatic cage to restore original factory performance.
• High-Temperature Durability: Features stainless steel internal components and a copper float resistant to corrosion and water hammer.
• Rapid Air Venting: The integrated thermostatic element handles large start-up air loads, essential for modulating pressure systems.
• Simplified Maintenance: Designed for in-line repair, allowing for quick component swap-outs without disconnecting the 3/4" NPT pipe connections.

Does this kit work with all Illinois Series G traps?
This specific 0036909 kit is optimized for the 6G model with 3/4 inch connections and a 15 PSI maximum operating pressure. Verify your trap body casting specifically lists the 6G-15 designation for proper seat and float alignment.

What is the primary cause of failure in these traps?
Most 6G-15 trap failures result from a water-logged copper float or a failed thermostatic air vent. This kit addresses both failure points by providing a brand-new float and thermostatic bypass assembly.

Is the cover gasket included in the 0036909 kit?
Yes, this internal rebuild kit includes the essential trap body gasket required to re-seal the cast iron housing after the internal components have been serviced.
