Lochinvar & A.O. Smith 100187862 Elbow
For veteran technicians and mechanical contractors, the Lochinvar & A.O. Smith 100187862 Elbow is a critical replacement component designed specifically for high-efficiency appliance venting. This 3-inch aluminum exhaust/condensate elbow is engineered to withstand the corrosive environment of a condensing boiler exhaust system or high-output commercial water heater. Unlike standard PVC fittings that may fail under high thermal stress, this OEM Lochinvar replacement part features a heavy-duty aluminum construction that ensures a secure, leak-proof seal for HVAC exhaust venting. This specific elbow, often identified as a 3" AL exhaust/condensate elbow, provides the necessary structural integrity for the evacuation of flue gases and acidic condensate. It serves as a direct boiler exhaust elbow replacement for several A.O. Smith and Lochinvar families, supporting optimal airflow and preventing backpressure issues in high-efficiency units. When performing a commercial water heater repair, using this authentic venting component is essential for maintaining system safety and long-term reliability in demanding applications.
Key Benefits for the Job Site- Precise 3-inch Diameter: Engineered for an exact fit on high-efficiency condensate drainage systems and exhaust ports.
- Corrosion-Resistant Aluminum: Built to handle the aggressive moisture and heat inherent in condensing appliance venting.
- OEM Integrity: Ensures full compatibility with specific A.O. Smith and Lochinvar model numbers, reducing troubleshooting time.
- Optimized Flow: Designed to maintain low-pressure drop and efficient exhaust gas expulsion for maximum appliance performance.
Is this elbow compatible with PVC or CPVC piping?
This aluminum elbow is specifically designed for systems utilizing 3-inch aluminum venting. Always verify your appliance's venting requirements in the technical manual before mixing materials, as transition adapters may be required for hybrid setups.
Can this be used for both intake and exhaust?
While physically capable of handling air intake, this component is professionally rated as an exhaust/condensate elbow, meaning it is built to handle the high temperatures and acidic discharge of the exhaust side.
Does this include mounting hardware or gaskets?
This part is typically supplied as the elbow assembly itself. We recommend inspecting the existing gaskets and seals during the removal of the old part and replacing them if any signs of compression set or degradation are present.
