The Multiquip 502402770 Felt Seal 6X8X188 is a genuine OEM component designed for MDR-9DYE, MDR-9D, and MDR-9GH power trowels.

Verified fitment for MDR-9 series machines means you can install with confidence and get back to finishing concrete without guesswork.
Key Features
- OEM-Grade Felt Material — Manufactured to the original fiber density and compression specification, ensuring the seal seats and retains properly against mating surfaces.
- Exact-Dimension Drop-In Replacement — The 6X8X188 sizing matches the original seal profile precisely, fitting the designated bore and shaft without trimming or modification.
- Confirmed MDR-9 Series Fitment — Verified for MDR-9DYE, MDR-9D, and MDR-9GH power trowels, so you know this is the right part before it ships.
- Keeps Contaminants Out of Critical Rotating Assemblies — A correctly seated felt seal blocks debris, dust, and moisture from reaching bearings and rotating components, preventing accelerated wear.
- Genuine Multiquip OEM Part — Supplied under Multiquip's OEM part program, backed by the same engineering that built the machine — not a generic substitute.
A felt seal serves as a barrier between rotating or reciprocating components and the surrounding environment, preventing the ingress of dirt, concrete dust, and moisture into bearing housings and gear assemblies. On a power trowel operating in abrasive concrete finishing conditions, this protection is critical — a degraded or missing felt seal allows contaminants to work into bearings and rotating shafts, causing accelerated wear and eventual failure of surrounding components. Replacing a worn felt seal promptly is one of the most cost-effective ways to extend the service life of the trowel's drivetrain.
