Multiquip 15721Z0DV70 Breather Tube Gx100U-Krbf Mtx7-70

The Multiquip 15721Z0DV70 Breather Tube Gx100U-Krbf Mtx7-70 is a genuine OEM component designed for MTX-series rammers including the MTX50HD, MTX60HD, MTX70HD, MTX70HF, MTX60HF, MTX70HDR, and MTX80HDR. Sourced directly from Multiquip, this part matches the original specification for a drop-in installation with no guesswork. Keeping the correct breather tube in service protects engine internals and ensures your rammer runs cleanly across demanding compaction applications. Verify your model code against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Construction — Manufactured to the exact material and dimensional specification of the original tube, ensuring proper airflow regulation for the GX100U engine series.
• Direct-Fit Installation — Engineered to connect at the original mounting points on MTX-series rammers, matching the factory routing path without adaptation.
• Broad MTX-Series Fitment — Compatible with MTX50HD, MTX60HD, MTX70HD, MTX70HF, MTX60HF, MTX70HDR, and MTX80HDR rammers.
• Engine Crankcase Protection — A correctly functioning breather tube vents crankcase pressure safely, preventing pressure buildup that can force oil past seals and contaminate the air-fuel mixture.
• Verified Multiquip Part Number — Order with confidence knowing 15721Z0DV70 is the correct OEM reference for this component across the listed rammer models.

The breather tube on a rammer engine serves as a controlled vent for crankcase gases, allowing internal pressure generated during combustion to escape without allowing contaminants to enter. On Honda GX100U-powered rammers, this tube channels those gases back into the air intake system where they are re-burned, keeping emissions controlled and the engine running cleanly. When the breather tube cracks, collapses, or becomes clogged, excess crankcase pressure builds up and can push oil past gaskets and seals, leading to oil consumption, smoke, and potential engine damage if left unaddressed.
