The Multiquip 43963-01 Magnetic Midi Filter O-Ring is a genuine OEM component designed for PRX series ride-on power float machines. Sourced directly from Multiquip, this O-ring delivers an exact seal match for the magnetic midi filter on PRX hybrid trowels, ensuring the hydraulic and fluid systems maintain proper containment without leaks. Keeping this seal in good condition is essential for protecting the filter housing and preventing fluid contamination that can compromise machine performance.
Key Features
- Genuine OEM Seal Material — Manufactured to Multiquip's original compound and durometer specifications, ensuring the correct compression and chemical resistance for this filter application.
- Direct-Fit Installation — Engineered to seat precisely within the magnetic midi filter housing on PRX ride-on power floats, requiring no trimming or adaptation during installation.
- PRX Series Compatibility — Confirmed fitment for PRX hybrid ride-on power float equipment, so you can order with confidence.
- Leak-Free Filter Sealing — A properly seated O-ring maintains a consistent fluid-tight barrier at the filter junction; a worn or cracked seal allows fluid bypass and can introduce contaminants into the system.
- Fuel and Fluid System Integrity — Replacing a degraded O-ring at the filter prevents unintended fluid loss that can lead to system pressure drops and accelerated wear on downstream components.
An O-ring at the magnetic midi filter serves as the primary seal between the filter housing and its mating surface, preventing fluid from bypassing the filter or escaping the circuit entirely. Over time, O-rings harden, crack, or deform due to heat cycling and fluid exposure, causing leaks that reduce system efficiency and can contaminate surrounding components. Replacing the Multiquip 43963-01 at the recommended service interval — or any time the filter is removed — keeps the filtration circuit sealed and functioning as intended.
