The Multiquip 3131 O-Ring is a genuine OEM sealing component designed for the MS-40H masonry saw and WM-700S, WM-700P, WM-900S, and WM-900P Whiteman plaster and mortar mixers. As an authentic Multiquip OEM part, the part is manufactured to the same specifications as the original, ensuring a proper compression fit and long-lasting seal integrity. Sourced directly through authorized channels, this O-Ring is a direct replacement that installs exactly as the factory-original component. If you're servicing your masonry saw or mixer and need a seal you can count on, Multiquip part 3131 is the correct choice.
Key Features
- OEM-Grade Seal Material — Manufactured to Multiquip's original compound and durometer specifications, delivering consistent compression and resistance to the fluids and pressures present in mixer and saw hydraulic circuits.
- Drop-In Seating — Sized to seat precisely in the original groove geometry, eliminating gaps or misalignment that lead to leaks during operation.
- Broad Fitment Across Two Equipment Families — Confirmed for the MS-40H masonry saw and WM-700S, WM-700P, WM-900S, and WM-900P Whiteman mortar and plaster mixers.
- Leak Prevention Where It Counts — A properly seated O-Ring maintains fluid containment and system pressure; a worn or degraded seal causes fluid loss, contamination, and eventual component damage.
- Genuine OEM Confidence — Supplied as an authentic Multiquip replacement part, so you're installing the same component the machine was built with — not an approximation.
An O-Ring is a simple but critical sealing element used throughout hydraulic, fluid, and mechanical assemblies to prevent leaks at joints, fittings, and mating surfaces. When correctly installed and in good condition, it forms an airtight or fluid-tight barrier under compression. Over time, O-Rings can harden, crack, or deform due to heat cycling, chemical exposure, or age — any of which allows fluid to bypass the seal, leading to pressure loss, contamination, or damage to surrounding components. Replacing a worn O-Ring promptly with the correct OEM part is one of the most cost-effective ways to keep fluid systems operating cleanly and efficiently.
