Multiquip 050200950 O-Ring DR-65 MT-70

The Multiquip 050200950 O-Ring DR-65 MT-70 is a genuine OEM seal designed for MTX70HD, MTX70HDR, MTX70HF, and MTX80HDR rammers. As a factory-sourced component, it matches the original material grade and dimensional profile specified for these machines. Verified fitment across the MTX70 and MTX80 rammer series means no guesswork when ordering a direct replacement. DHS Equipment stocks this part to keep your Multiquip rammer running without unnecessary delay.

Key Features

• Genuine OEM Sealing Material — Factory-specified elastomer compound ensures correct compression set and chemical resistance for the fluid and pressure conditions inside these rammers.
• Exact Dimensional Match — DR-65 profile seats into the original groove without adjustment, maintaining the intended sealing surface contact on installation.
• Confirmed Rammer Fitment — Compatible with MTX70HD, MTX70HDR, MTX70HF, and MTX80HDR models across the MTX rammer series.
• Leak Prevention at the Source — A worn or cracked O-ring allows fluid bypass that degrades stroke performance and accelerates wear on surrounding components; replacing it restores full sealing integrity.
• Fuel System Safety Relevance — Where this O-ring interfaces with the fuel circuit, a correctly seated OEM seal prevents fuel leakage and the associated fire and vapor hazard on active jobsites.

An O-ring is a precision-molded loop of elastomer that creates a pressure-tight seal between two mating surfaces or around a moving shaft. In a rammer, O-rings are used throughout the fuel system, carburetor, and internal hydraulic or pneumatic circuits to prevent fluid and air leaks that would otherwise rob the machine of striking force or cause a fuel hazard. When an O-ring ages, hardens, or takes a compression set, it can no longer conform to its mating surfaces under pressure, resulting in visible leaks, rough running, or a loss of impact energy. Replacing it promptly with the correct OEM part restores the designed seal and protects the components around it.
