Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring correct tube diameter, length, and material grade for proper crankcase venting performance.
- Direct-Fit Replacement — Engineered to connect directly to the existing breather port, matching the original routing and retention points on supported models.
- Broad Multiquip Fitment — Compatible with AR13H, AR13HA/HAR, AR13HC, MRH800GS, V305EH, MC12PH, and GA9.7HE series equipment, covering ride-on rollers, walk-behind rollers, mixers, and generators.
- Crankcase Pressure Control — A correctly functioning breather tube maintains balanced crankcase pressure, protecting engine seals and preventing oil contamination of the air intake.
- Long-Term Engine Protection — Replacing a cracked or collapsed breather tube prevents oil blow-by, excess emissions, and accelerated internal engine wear on your Multiquip equipment.
The breather tube routes crankcase gases away from the engine's internal components and back into the air intake or atmosphere, depending on the engine design. It relieves pressure that builds up inside the crankcase during normal combustion cycles, preventing oil from being forced past seals and gaskets. When the breather tube cracks, collapses, or becomes blocked, crankcase pressure rises unchecked, leading to oil leaks, increased oil consumption, and potential seal damage that can shorten engine life significantly.
