Multiquip 1576673330 Water Flange Gasket

The Multiquip 1576673330 is a genuine OEM Water Flange Gasket designed for the DAW-500S diesel arc welder and DCA15SPX3 and DCA10SPX3 ultra-silent diesel generators. As a direct OEM replacement, this gasket is manufactured to the exact material grade and compression specifications required by these machines, ensuring a leak-free seal at the water flange connection. Sourced directly through Multiquip's authorized parts network, the part is the correct service part for keeping coolant passages properly sealed during maintenance or repair work on compatible units.

Key Features

• OEM-Grade Sealing Material — Manufactured to the exact compression and material specifications required at the water flange, ensuring consistent coolant containment under operating temperatures and pressures.
• Drop-In Flange Replacement — Matches the original flange geometry exactly, seating flush against the mating surfaces without trimming or reworking the surrounding hardware.
• Confirmed Fitment — Correct service part for the DAW-500S diesel arc welder, DCA15SPX3, and DCA10SPX3 ultra-silent diesel generator models.
• Coolant System Integrity — A properly seated water flange gasket maintains pressurized coolant flow through the engine, preventing overheating that can cause costly engine damage or unplanned shutdowns.
• Fuel and Coolant Safety Compliance — A failed or improperly seated coolant gasket can allow fluid migration near hot engine surfaces; replacing with the correct OEM part supports safe, compliant operation of fuel-and-cooling-adjacent systems.

The water flange gasket seals the joint between the water flange fitting and the engine's cooling passage, keeping pressurized coolant contained within the system. Without an intact seal at this point, coolant can leak externally or migrate into areas where it causes corrosion or overheating, ultimately leading to engine failure. Replacing a worn or damaged gasket with the correct OEM part restores the integrity of the cooling circuit and protects the engine from the thermal stress that follows any loss of coolant flow.
