User Reviews & Q&A Summary:
A 30" screw-in thermocouple used on compatible Weil-McLain boilers to support standing-pilot safety operation by sensing pilot flame and enabling gas valve operation.
Key Features:
- Screw-in thermocouple replacement part
- 30" length
- Listed for use with Weil-McLain CG Boilers, CGa Boilers, EG Boilers, and EGH Boilers
Compatibility & Applications:
- Used With : CG Boilers; CGa Boilers; EG Boilers; EGH Boilers
- Q&A guidance indicates this part is used for certain natural gas (NG) applications, and a different thermocouple part number may be required for LP/propane versions
- Must only be used where the manufacturer specifies this exact part number: 511-724-254
Installation & Operation Notes:
- Installation should be performed by a qualified boiler/HVAC service professional
- Refer to the boiler's service/installation manual for the correct thermocouple replacement procedure, pilot/gas valve connection details, and post-service safety checks
Maintenance & Troubleshooting:
- This thermocouple is commonly replaced when a standing-pilot boiler won't stay lit or loses heat due to a failed/weak thermocouple
- Q&A highlights that confirming a failed thermocouple requires proper troubleshooting steps; follow the boiler's service manual or a qualified technician's diagnostics
- If the boiler is LP/propane or if issues persist after replacement, confirm the correct fuel-specific part number and continue troubleshooting per the boiler's service documentation
User Reviews & Q&A Summary:
- Reviews commonly report an exact OEM-style fit and straightforward replacement, with many noting it restored heat/pilot operation quickly
- Frequent themes include good quality/longer-lasting performance compared with "universal" thermocouples, plus fast shipping and good service
- Q&A themes emphasize model-specific verification (often requiring full model/serial), and confirm it is not a universal fit for other brands/models
- Q&A also notes fuel and thread considerations: users ask about LP/propane and special thread types (e.g., left-hand), and responses emphasize using the exact manufacturer-specified part for the specific boiler configuration

Good quality products at good prices
Thermocouple was exact fit, identical to 25yr old original for radiant floor Weil Mclain boiler. Been doing business with SH for years. They have a great business model. Fitment database is accurate, products are top quality, prices fair. Never a problem. Keep up the good work.

WEIL-McLAIN OEM PART
Got this as a backup, was told by a technician that the oem thermocouple is better quality than the universal ones they use.

Exact part, fast delivery, excellent price
What more can I say? Much lower price than some suppliers. Very reasonable next day delivery for under $5 to my doorstep. Simple part, but I had no heat without it. Will shop here in future.
