Water pump Gasket LS 1997-Up Metal/Rubber

The Water pump Gasket LS 1997-Up Metal/Rubber from Straub Technologies Inc. is a precision OEM-specification replacement seal designed for LS-platform engine cooling systems. This gasket is essential for anyone rebuilding a stock LS engine, managing a high-mileage vehicle, or assembling a custom LS swap, as it prevents coolant leakage at the water pump mounting surface.

Constructed with a dual-composition of metal and rubber, this gasket ensures both structural integrity and conformability across the pump mounting face. The metal core provides a rigid sealing surface that withstands the cyclic thermal expansion typical of LS engines, while the bonded rubber layer compresses to seal micro-surface irregularities. This design guarantees zero gap intrusion, maintaining coolant pressure integrity across all operating ranges.

Mechanics and engine builders prefer this gasket for any LS platform engine manufactured from 1997 onward, including LS1, LS2, LS3, LS9, and their variants. Its reliable performance is crucial for forced-induction builds, street performance applications, and race engines where sustained heat and pressure are present.
