Multiquip 1136 Bracket Seal

The Multiquip 1136 Bracket Seal is a genuine OEM component designed for ST4 and ST6 series submersible pumps as well as HHN and J series walk-behind and ride-on power trowels. As a direct OEM replacement, this seal is manufactured to the same specifications as the original part, ensuring a consistent, dependable fit across all compatible equipment. Confirmed fitment includes the ST61230, ST61460, ST41230, ST41460, HHNG5, HHN34TVD, HHN31V, and J36E2, among other models in these families. Sourcing the correct bracket seal by part number 1136 helps maintain the integrity of the bracket assembly and prevents premature wear or fluid intrusion.

Key Features

• Genuine OEM Sealing Material — Manufactured to the original compression and material grade specifications, ensuring the seal performs consistently under the operating conditions of both submersible pump and power trowel applications.
• Direct Bracket Drop-In Replacement — Engineered to seat correctly within the existing bracket housing with no rework to mating surfaces or mounting points.
• Broad Confirmed Fitment — Compatible with ST4 and ST6 series submersible pumps and HHN and J series power trowels, including the ST41230, ST41460, ST61230, ST61460, HHNG5, HHN34TVD, HHN31V, and J36E2.
• Protects Bracket Integrity — A correctly seated bracket seal prevents contaminant ingress and moisture migration into the bracket assembly, which can accelerate corrosion and bearing wear if left unchecked.
• Fluid Containment Compliance — On submersible pump models, maintaining an effective bracket seal is critical to preventing internal fluid bypass that can reduce pump output and damage surrounding components.

The bracket seal forms a tight barrier at the junction between the bracket housing and adjoining components, preventing water, slurry, or environmental contaminants from entering the assembly. In submersible pump applications, a compromised seal can allow fluid to migrate into the bearing cavity, leading to accelerated wear and eventual mechanical failure. On power trowel models, the seal helps protect the bracket and shaft interface from debris intrusion during concrete finishing operations, maintaining smooth rotation and consistent blade performance.
