The Multiquip EM25169 Rubber Gasket is a genuine OEM component designed for the ST-45HRM concrete pump.

Sourced directly through Multiquip's authorized parts network, EM25169 is the correct part for ST-45HRM service and maintenance.

Key Features

• OEM-Grade Rubber Compound — Manufactured from the same rubber material spec as the original, delivering the compression and chemical resistance required in a concrete pump environment.
• Drop-In Replacement — Matches the original gasket profile and dimensions for a straightforward swap during scheduled service or unplanned repairs on the ST-45HRM.
• ST-45HRM Fitment — Confirmed fit for the Multiquip ST-45HRM swing-tube concrete pump; verify your model before ordering.
• Leak Prevention — A correctly seated gasket maintains a tight seal under operating pressure, preventing material bypass and protecting surrounding components from premature wear.
• Genuine Multiquip OEM Part — Supplied as an authorized Multiquip replacement under part number EM25169, ensuring traceability and consistency with original equipment standards.

A rubber gasket creates a compression seal between mating surfaces in the pump assembly, preventing concrete slurry, water, or air from bypassing the joint under pressure. When a gasket deteriorates, cracks, or loses elasticity, it allows material to leak past the sealing surface, which can lead to pressure loss, contamination of surrounding components, and accelerated wear on adjoining parts. Replacing a worn gasket promptly with the correct OEM part keeps the pump operating at its intended pressure and output capacity.
