Lochinvar & A.O. Smith 100287071 Gasket
The Lochinvar & A.O. Smith 100287071 Gasket is a critical OEM replacement part engineered for high-performance Knight boiler and water tube systems. Labeled as the K Gasket, this component is purpose-built to maintain a hermetic seal within the water tube 56-156 range, specifically compatible with models such as the KHB055N, KHB085N, KHB110N, KHB155N, and WHN156. Designed to withstand the rigorous thermal cycling and pressure differentials found in 1-inch water pipe applications, it prevents bypass and external leakage that can compromise hydronic heating efficiency.
For service technicians, ensuring the integrity of the heat exchanger assembly is paramount. Replacing a worn 100287071 water tube gasket during routine maintenance prevents the common failure point of localized corrosion caused by weeping joints. This gasket is manufactured to exact Lochinvar specifications, utilizing high-grade elastomers that resist degradation from chemically treated boiler water. Whether you are performing a full teardown or addressing a minor leak, using a genuine Lochinvar gasket ensures the system returns to its original design pressure and flow characteristics without the risk of premature seal failure.
Key Benefits:- Precision Compatibility: Engineered specifically for the Lochinvar Knight and A.O. Smith water tube series (56-156), ensuring a perfect fit for 1" pipe connections.
- Leak Prevention: High-density material creates a robust barrier against moisture ingress and pressure loss, maintaining energy efficiency.
- Thermal Resilience: Specialized compound retains elasticity under constant HVACR heating and cooling cycles to prevent hardening or cracking.
- OEM Reliability: Provides the exact technical specifications required for mission-critical boiler maintenance and professional repairs.
- Is this gasket compatible with all Knight XL models? While it fits many in the 56-156 range, always verify the specific SKU 100287071 against your unit’s parts list to confirm the exact water tube diameter.
- What are the signs that this gasket needs replacement? Look for calcium buildup or "whitening" around the tube joints, as well as minor pressure fluctuations within the hydronic system.
- Does this require a specialized sealant? Typically, these OEM gaskets are designed for dry or lubricated installation; check your specific service manual to see if RTV or a thread sealant is recommended for your water tube application.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
