The Multiquip EM16173 O-Ring is a genuine OEM sealing component built for a wide range of Multiquip equipment families, including MVC64VH, MVC64VHW, MVC90H, MVH304GSB, QP205SH, QP402H, QP3TH, WM120PH, WM120SH, WM70S/P, MC44S, MC64P/S, MP series masonry saws, SP series flat saws, CA-4-4H, CA4HM, R2000H, G55H, GA6HZ, and Essick mixer series. As a genuine OEM part, EM16173 is sourced directly through Multiquip to ensure the correct material grade, cross-section diameter, and compression characteristics for each application it serves. When an O-ring fails, it can lead to fluid leaks, loss of pressure, contamination ingestion, and accelerated wear on surrounding components — making prompt, correct replacement essential. DHS Equipment stocks the EM16173 to get your machine back in service with the part Multiquip specifies.
Key Features
- Correct Sealing Material — Manufactured to OEM-specified elastomer grade, ensuring proper compression set, chemical resistance, and temperature tolerance for the fluid and environment it seals against.
- Exact Cross-Section and Diameter — Matches the OEM groove dimensions exactly, so the ring seats flush and forms a consistent seal without under- or over-compression upon installation.
- Broad Multi-Family Fitment — A single verified part number covering plate compactors (MVC64VH, MVC90H, MVH304GSB), centrifugal and trash pumps (QP205SH, QP402H, QP3TH), Whiteman and Essick mixers, masonry and flat saws (MP and SP series), walk-behind trowels, and more.
- Leak Prevention at the Source — A correctly installed O-ring maintains fluid or air pressure boundaries that keep pumps primed, hydraulic circuits responsive, and fuel systems sealed — a failed ring can cascade into pump cavitation or fuel starvation.
- Genuine OEM Traceability — Sourced through Multiquip's authorized parts channel, so part number EM16173 is the exact component validated for these applications — no guesswork on material or sizing.
An O-ring is a molded elastomeric loop seated in a machined groove to create a static or dynamic pressure seal between two mating surfaces. It works by deforming slightly under compression when the joint is assembled, blocking the passage of fluids, fuel, air, or contaminants at that interface. When an O-ring ages, hardens, cracks, or is damaged during disassembly, it loses the ability to maintain that seal — resulting in leaks that can compromise pump output, introduce air into fuel systems, or allow abrasive contaminants to reach precision internal components. Replacing a worn O-ring with the correct OEM-specified part restores the integrity of the sealed joint and protects the surrounding assembly from secondary damage.
