Key Features

• OEM Sealing Material: — Manufactured to the correct compression and material spec for the thermostat housing, ensuring a pressure-tight seal without over-compression or distortion.
• Drop-In Thermostat Housing Fit: — Seats directly into the thermostat housing with no trimming or modification, matching the original gasket profile exactly.
• Broad Diesel Equipment Compatibility: — Fits DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, DAC7000SSA, and DLW300ES series units from Multiquip.
• Cooling System Integrity: — A properly sealed thermostat gasket keeps coolant flowing through the correct circuit and prevents bypass leaks that cause overheating and engine damage.
• Genuine OEM Part: — Supplied directly by Multiquip, so you receive the same component installed at the factory — critical for maintaining cooling system performance on high-output diesel generators and welders.

The thermostat gasket forms the sealing layer between the thermostat and its housing in the engine cooling circuit. Its job is to prevent coolant from bypassing or leaking at the thermostat junction, keeping the system pressurized and directing coolant flow correctly as the engine reaches operating temperature. When this gasket fails or deteriorates, coolant can seep past the housing, leading to coolant loss, erratic temperature regulation, and ultimately engine overheating — making timely replacement essential to protecting the engine.
