The Multiquip 0481100120 O Ring is a genuine OEM O Ring designed for the DAW-500S diesel arc welder. As an authorized Multiquip OEM part, it is manufactured to the exact material and dimensional specifications required for proper sealing performance on the DAW-500S. Sourced directly through the Multiquip parts network, this O Ring is the correct replacement when the original seal shows signs of wear, compression set, or leakage.
Key Features
- OEM-Grade Seal Material — Manufactured to the exact elastomer compound and durometer rating specified for the DAW-500S, ensuring consistent compression and a leak-free seal under operating conditions.
- Drop-In Replacement — Matches the original groove dimensions and cross-section of the factory-installed O Ring, seating correctly without modification to mating surfaces.
- Confirmed Fitment — Verified for use on the Multiquip DAW-500S diesel arc welder series.
- Prevents Fluid or Air Loss — A correctly seated O Ring maintains system pressure and prevents contamination ingress, keeping fuel, hydraulic, or coolant circuits functioning as designed.
- Fuel and Fluid System Safety — A failed or swollen O Ring in a fuel or hydraulic circuit can lead to leaks that create fire or operational hazards; replacing with a genuine OEM part restores the original sealing integrity.
An O Ring is a circular elastomeric seal used to close the gap between two mating components, preventing the passage of fluids, gases, or contaminants. On equipment like the DAW-500S, O Rings are found throughout fuel delivery, hydraulic, and cooling circuits where maintaining a pressure-tight connection is critical to safe and consistent operation. When an O Ring degrades — through heat cycling, chemical exposure, or mechanical compression set — it loses its ability to seal, resulting in leaks, pressure loss, or contamination that can impair performance and create hazardous conditions if left unaddressed.
