Lochinvar & A.O. Smith 100233625 Gasket
The Lochinvar & A.O. Smith 100233625 Gasket is a critical copper tube sealing component engineered for high-recovery commercial water heaters and hydronic boiler systems. This water tube gasket is designed specifically for a precision fit on Lochinvar SNR126, SNRA151, and SNR201 models, as well as NKC 110-199 (N,L) combi boilers. Featuring dimensions of 1.2" OD x 0.78" ID x 0.13" Thickness, this high-grade copper gasket provides a robust thermal and pressure seal, preventing bypass leaks and maintaining system head pressure during peak firing rates. As a direct OEM replacement part (superseding 100276509 and GKT20023K), it ensures material compatibility with copper heat exchanger manifolds, eliminating the risk of galvanic corrosion often seen with inferior aftermarket alternatives. For field technicians, using the correct Lochinvar 100233625 is essential for restoring the watertight integrity of the heat exchanger assembly after routine descaling or manifold maintenance.
Key Benefits:
- Precision Dimensions: Exact 0.78" ID and 1.2" OD sizing ensures a drop-in fit for Lochinvar SNR and NKC series water tubes.
- High-Grade Copper Construction: Optimized for high-temperature hydronic applications, providing superior deformation properties for a reliable metal-to-metal seal.
- Broad Compatibility: Validated for use in Lochinvar Knight Combi and A.O. Smith commercial water heating units.
- OEM Integrity: Prevents system pressure loss and potential water damage by meeting original manufacturer pressure ratings.
- Direct Cross-Reference: Replaces legacy part numbers GKT20023, GKT20023K, and 100146354 for simplified inventory management.
Common Questions:
Can I reuse the old gasket if it looks intact?
Copper gaskets are designed to crush and conform to the seating surface upon initial torque. Once compressed, they lose their elasticity. Always install a new 100233625 gasket kit whenever the water tube connection is broken to prevent pinhole leaks under pressure.
Which Lochinvar models use this specific copper tube gasket?
This part is the standard spec for SNR126, SNR151, and SNR201 models, and is also required for the water tube connections on NKC 110-199 residential combi boilers.
Does this gasket require additional pipe dope or sealant?
No. When installed between clean, burr-free copper surfaces and torqued to manufacturer specifications, the copper material creates a mechanical seal. Use of unauthorized sealants may interfere with the seat and lead to premature failure.
