The Multiquip 4802 Mechanical Seal Sleeve O-Ring is a genuine OEM sealing component designed for a range of Multiquip rollers and hydraulic ride-on power trowels, including the RW1504HF, RW1403HF, RW1404, RW1404MR, MD105, and MD80, as well as the QP205SH centrifugal pump. As a direct OEM replacement sourced through authorized supply channels, the 4802 delivers the same material grade and dimensional tolerancing as the original part — so you can be confident it will seat and compress correctly in the mechanical seal sleeve. Verify your model and serial number against the fitment list before ordering, particularly for RW1504HF units up to S/N and RW1404MR units from S/N 326075 and up.
Key Features
- OEM-Grade Seal Material — Manufactured to the same compound specification and cross-section tolerances as the original, ensuring correct compression against the mechanical seal sleeve without under- or over-sealing.
- Drop-In Sleeve Fit — Dimensioned to seat directly into the mechanical seal sleeve housing with no trimming or sizing required, maintaining proper sealing geometry on installation.
- Broad Multiquip Fitment — Covers multiple equipment families including RW-series walk-behind rollers (RW1504HF, RW1403HF, RW1404, RW1404MR), MD-series hydraulic ride-on trowels (MD105, MD80), and the QP205SH centrifugal pump.
- Leak Prevention at the Mechanical Seal — A correctly installed O-ring at the seal sleeve interface prevents fluid ingress and egress that would otherwise contaminate bearings, degrade hydraulic fluid, or cause pump seal failure.
- Serial Number Specific Fitment Available — Fitment data accounts for serial number breaks on the RW1504HF (up to S/N 1534188) and RW1404MR (S/N 326075 and up), reducing the risk of ordering the wrong seal profile.
The mechanical seal sleeve O-ring forms the secondary sealing barrier around the mechanical seal sleeve, preventing fluid from bypassing the seal interface and escaping along the shaft or into surrounding components. In rollers and trowels, this seal protects critical drivetrain or hydraulic interfaces from contamination; in pump applications it keeps the pump chamber pressurized and leak-free. When this O-ring hardens, cracks, or takes a set from heat cycling, it loses its ability to maintain that seal — leading to visible leaks, accelerated seal wear, and potential damage to adjacent components if left uncorrected.
