Multiquip 25389-503 T350 Seal Kit

The Multiquip 25389-503 T350 Seal Kit is a genuine OEM Seal Kit designed for the T-350 trash pump. As a factory-sourced component, this kit delivers the exact seals specified for the T-350, ensuring a proper fit and restored pump integrity right out of the box. Sourced directly through Multiquip's OEM supply chain, this kit is the correct choice when servicing T-350 units and keeping fluid containment where it belongs.

Key Features

• OEM Sealing Material Match — Genuine Multiquip seals are manufactured to the correct material grade and compression specification for the T-350 pump's fluid environment, delivering consistent sealing under operating pressure.
• Complete Kit for a Full Service — Includes all seals needed for a proper service interval, so you are not hunting for individual components or making multiple orders.
• Direct Fitment for the T-350 — Engineered specifically for the Multiquip T-350 trash pump, this kit installs into the existing pump housings and seal seats without adaptation.
• Restores Pump Efficiency — Worn or failed seals allow fluid bypass and pressure loss inside the pump. Replacing with this part restores proper prime, flow rate, and discharge performance.
• Fuel and Fluid System Integrity — Correct sealing prevents external leaks that can create hazardous conditions on the jobsite, making timely seal replacement an important safety and compliance step for pump operators.

A seal kit serves as the primary barrier between the internal fluid passages of a pump and the outside environment. In a trash pump like the T-350, seals are subjected to continuous exposure to abrasive slurry, water, and debris, causing gradual wear that leads to leaks, loss of prime, and reduced discharge pressure. Replacing worn seals with the correct OEM components restores the pump's ability to move fluid efficiently and prevents contamination of bearings and other internal parts that accelerate broader pump failure.
