The Multiquip 18329ZB4000 is a genuine OEM Seal GA 3.6H 6HH designed for Multiquip GA and GAW series gasoline-powered generators and arc welders, including the GA6HB, GA6HEB, GA3.6HZ, GA3.6HA, GA6HR, GA6HRS, GA6HRSNC2, GA3.6HR, GAC3.6HR, GAC6HR, GAC6HRS, GAW180HE, GAW180HEA, and GAW180HE1. As a genuine OEM component sourced directly through Multiquip's authorized parts network, part 18329ZB4000 meets the exact material and dimensional specifications of the original seal installed at the factory. Keeping this seal in proper condition is essential to the long-term integrity of the engine assembly on these units. DHS Equipment supplies this part to contractors and equipment operators who demand a verified OEM fit with no guesswork on compatibility.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the exact material grade and compression specification of the original, ensuring a consistent fluid-tight barrier in the engine assembly.
- Direct-Fit Replacement — Engineered to install in the same position as the factory seal, with matching geometry that mates correctly to adjacent engine components without alteration.
- Broad GA and GAW Series Coverage — Confirmed fitment across GA6HB, GA6HEB, GA3.6HZ, GA3.6HA, GA6HR, GA3.6HR, GAC3.6HR, GAC6HR, GAC6HRS, GAW180HE, GAW180HEA, and GAW180HE1 units.
- Sustained Generator and Welder Output — A properly seated seal prevents oil migration and contamination that can degrade engine performance, protecting the consistent power output these generators and welders depend on.
- Fuel and Oil System Safety — On gasoline-powered equipment, a compromised seal can allow fuel or oil to reach ignition sources; replacing a worn seal with a genuine OEM part directly supports safe operation.
An engine seal serves as a precision barrier between rotating or stationary components, preventing oil or other fluids from escaping the controlled environment of the engine assembly. In gasoline-powered generators and arc welders like the GA and GAW series, maintaining this barrier is critical — a failing seal can lead to oil leaks, fluid contamination, loss of lubrication, and ultimately engine damage. Replacing a worn or cracked seal promptly with a correctly specified OEM part restores the engine's fluid management system and protects the components around it.
