Laars Heating Systems 10391302 Flange Mach

Laars Heating Systems 10391302 Flange Mach

The Laars Heating Systems 10391302 is a precision-engineered cast iron flange designed for high-demand hydronic heating and domestic hot water applications. Featuring a 2-inch 11-1/2 NPT threaded connection, this machined component ensures a leak-proof seal and structural integrity within the header assembly of commercial boilers and volume water heaters. Professionals frequently utilize this OEM replacement part to maintain the factory performance of Laars MightyTherm and Laars Pennant series units, where secure piping alignment is critical to system efficiency.

Built for industrial-grade durability, the 10391302 flange mach resists thermal stress and corrosion common in high-temperature heating loops. Whether you are performing a full header teardown or a routine component swap, the exact machining of this flange's NPT threading allows for seamless integration with existing 2" pipe schedules. This part is a direct replacement for Laars S00636, providing the reliable mechanical connection needed to prevent pressure loss and ensure consistent circulation across the heat exchanger.

Key Benefits
  • Direct OEM Compatibility: Verified for use in Laars MightyTherm (500L-850N) and Pennant (PNCV/PNCH 500-2000) models.
  • Heavy-Duty Construction: High-grade cast iron provides superior resistance to mechanical fatigue and high-pressure environments.
  • Precision Threading: Machined 2" 11-1/2 NPT threads ensure a secure fit and minimize the risk of fluid bypass.
  • Optimized Performance: Maintains exact component alignment, which is critical for the longevity of primary boiler heat exchangers.
Common Questions

What boiler models is this flange compatible with?
This part is specifically engineered for the Laars MightyTherm and Pennant series, covering a range of BTU sizes from 500 up to 2000 units.

Does this include the necessary gasket for installation?
The 10391302 is the machined flange only. It is highly recommended to replace the Laars S0063700 flange gasket simultaneously to ensure a complete, gas-tight and water-tight seal.

What is the primary material of the 10391302?
It is constructed from rugged cast iron, though some variations in specific system designs may require a bronze alternative (10391304) for certain potable water applications. Always verify material requirements based on the specific job site water chemistry.
