Multiquip 49038000 Packing Ring E78G MQ-40TDH

The Multiquip 49038000 is a genuine OEM Packing Ring E78G MQ-40TDH designed for RAMMAX walk-behind roller models RW1404, RW1404MR, and RW1504HF. As a direct Multiquip OEM part, 49038000 is manufactured to the exact material and dimensional specifications required for proper sealing performance in your roller's hydraulic or fluid system. Confirm your serial number range before ordering — this part fits RW1404MR units from S/N 326075 and up and RW1504HF units up to S/N. Sourcing the correct packing ring is critical to preventing fluid leaks and maintaining full compaction output on the job.

Key Features

• Genuine OEM Sealing Material — manufactured to the precise compression and material grade specified for the MQ-40TDH packing application, ensuring an effective fluid seal without improvisation.
• Direct Drop-In Replacement — matches the original profile and dimensions of the production part, seating correctly in the existing bore or housing without rework.
• Confirmed Fitment for RAMMAX Rollers — compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188); verify your serial number before ordering.
• Preserves Hydraulic System Integrity — a properly seated packing ring prevents internal and external fluid bypass, keeping system pressure consistent and drum compaction force at rated output.
• Prevents Costly Fluid Loss and Contamination — a worn or extruded packing ring allows fluid to migrate past the seal, leading to pressure drop, component wear, and potential hydraulic system damage if left unaddressed.

A packing ring is a precision sealing element used within hydraulic cylinders, pumps, or fluid-carrying assemblies to prevent leakage between moving and stationary components. It works by maintaining a compression seal against the bore wall or shaft, containing pressurized fluid and keeping contaminants out of the system. When a packing ring wears, hardens, or becomes extruded from its groove, fluid bypasses the seal — causing pressure loss, visible leaks, and reduced force output that directly impacts the roller's compaction performance.
