Multiquip 578014 O-Ring AS-014

The Multiquip 578014 O-Ring AS-014 is a genuine OEM seal designed for SP4 flat saws and SP6457 pavement saws. As a direct OEM replacement, the part is manufactured to the exact material compound and dimensional tolerancing specified for these machines, ensuring a proper seal without modification. Sourced directly through Multiquip's authorized parts network, this is the same component used in original production — the right choice when seal integrity matters.

Key Features

• OEM Material Compound: — Manufactured to the exact elastomer specification for the AS-014 cross-section, maintaining compression set resistance and sealing force under operating pressures.
• Drop-In Replacement: — Matches the original groove dimensions for the SP4 and SP6457, seating correctly without stretching or pinching during installation.
• Confirmed Fitment: — Verified for SP4 flat saws and SP6457 pavement saws; check your model code before ordering to ensure correct application.
• Leak Prevention: — A properly seated O-Ring maintains fluid or pressure containment within the system; a worn or damaged seal can lead to leaks, contamination, and accelerated component wear.
• Fuel and Fluid System Integrity: — Where used in fuel or hydraulic circuits, correct O-Ring material is critical to resisting chemical degradation and preventing hazardous leaks.

An O-Ring is a loop-shaped elastomeric seal seated in a machined groove to prevent the passage of fluid, air, or debris between mating components. In saw applications, O-Rings are commonly found in fuel system connections, water delivery circuits, and hydraulic or blade-drive assemblies. When an O-Ring hardens, cracks, or loses its cross-sectional shape, it can no longer maintain a reliable seal — resulting in fluid leaks, pressure loss, or contamination that degrades the performance and longevity of surrounding components.
