Multiquip 21046 Gasket Seal Kit

The Multiquip 21046 Gasket Seal Kit is a genuine OEM replacement designed for a wide range of Whiteman and International walk-behind power trowel series, including J36, JA, B46, BA, CA, BH, and BS series machines. As a factory-sourced kit, it delivers the exact sealing materials and gaskets needed to restore proper function during service or overhaul. This kit covers an extensive list of compatible models — from BH11C and BH90C to JH90C, BS46H90, CA4HC, HPHA36C5H, and the J36 family — making it a reliable go-to for technicians working across multiple trowel platforms. Keeping a 21046 Gasket Seal Kit on hand simplifies scheduled maintenance and unplanned repairs alike.

Key Features

• Genuine OEM Sealing Materials — Manufactured to Multiquip's original material and compression specifications, ensuring each gasket and seal performs exactly as designed for trowel applications.
• Complete Kit Format — Includes all required gaskets and seals in a single kit, so technicians have every component needed for a full service without sourcing individual pieces separately.
• Broad Walk-Behind Trowel Coverage — Compatible with J36, JA, B46, BA, CA, BH, BS, JH, JS, HPHA, HPLA, PRO36, PRO46, and SCT series walk-behind power trowels from the Multiquip portfolio.
• Restores Proper Sealing Integrity — Worn or degraded gaskets and seals allow oil and fluid migration that accelerates internal wear; replacing them with OEM-spec components brings the machine back to proper operating condition.
• Correct Drop-In Replacement — Engineered to match original dimensions and mate surfaces, allowing straightforward installation without machining or modification during teardown and rebuild.

A gasket and seal kit serves as the critical barrier between fluid passages, mating surfaces, and the external environment inside a power trowel's gearbox and engine assemblies. Gaskets prevent oil and other fluids from leaking past joined surfaces, while seals keep contaminants such as dirt and water from entering rotating or reciprocating assemblies. When these components deteriorate — through heat cycling, age, or mechanical wear — fluid leaks and contamination can cause accelerated internal damage, leading to costly repairs. Replacing gaskets and seals at recommended service intervals, or any time an assembly is opened, is one of the most effective ways to extend the working life of a walk-behind trowel.
