The Multiquip 18329ZB2000 is a genuine OEM GX160 Muffler Protector Seal designed for GAC2.2HZ, GA2.5HR, and GAC2.5HR gasoline-powered generators. As a direct OEM replacement, this seal delivers the exact material grade and dimensional tolerances required for proper muffler sealing on GX160-equipped units.

Keep a spare on hand to minimize unplanned service interruptions during peak operation.

Key Features

• OEM-Grade Sealing Material — Manufactured to the same heat-resistant material specification as the original, maintaining a proper exhaust seal at the muffler interface on GX160-equipped generators.
• Direct Drop-In Replacement — Engineered to match the original mounting profile exactly, seating against the muffler protector assembly without rework or trimming.
• Confirmed Fitment for GAC and GA Series Generators — Verified for GAC2.2HZ, GA2.5HR, and GAC2.5HR Multiquip gasoline-powered generator models.
• Preserves Exhaust Integrity — A correctly seated muffler protector seal prevents exhaust gas escape at the joint, keeping the generator running cleanly and at full rated output.
• Exhaust Safety Compliance — Proper sealing at the muffler protector is critical to preventing hot exhaust gases from escaping near the unit's housing — use only a correctly rated replacement seal.

The muffler protector seal sits between the muffler and its heat shield or protector assembly, forming a gas-tight barrier that contains exhaust gases and directs heat away from surrounding components. On GX160-powered generators, this seal endures sustained high-temperature cycling, and a cracked or compressed-out seal can allow exhaust gases to escape at the joint — reducing engine efficiency and creating a potential heat hazard near the generator's enclosure. Replacing it at the first sign of leakage or visible deterioration keeps the exhaust system functioning as designed.
