The Multiquip 0191300500 Blowby Hose is a genuine OEM component designed for DCA-series ultra-silent and super-silent diesel generators, including the DCA125SSIU, DCA70SSIU, DCA180SSIU, DCA180SSIU, DCA56SPX, and DCA45SSIU2-GEER. As a direct OEM part, the part is manufactured to the same specification as the original, ensuring a correct connection to the crankcase ventilation system without any fitment guesswork. This hose is also compatible with the DCA125SSIU50HZ, DCA125SSIU60HZ, DCA70SSIU50HZ, and DCA70SSIU60HZ frequency variants, as well as the DIS185SSI4F air compressor. When it comes to crankcase system integrity, sourcing the correct OEM hose keeps your generator running clean and within spec.
Key Features
- Genuine OEM Construction — Molded to exact dimensional and material tolerances for proper crankcase ventilation routing in DCA-series diesel power equipment.
- Drop-In Replacement — Connects directly to the existing crankcase ventilation fittings with correct end sizing and hose routing geometry matched to the original installation.
- Broad DCA Series Compatibility — Confirmed fitment across DCA125SSIU, DCA70SSIU, DCA180SSIU, DCA56SPX, DCA45SSIU2-GEER, and multiple 50Hz and 60Hz variants.
- Crankcase Pressure Control — Maintains correct blowby gas routing from the engine crankcase; a cracked or deteriorated hose allows oil mist to escape, creating contamination and potential engine wear.
- Emissions System Integrity — On Tier 4 and ultra-silent generator models, a properly seated blowby hose is essential for maintaining correct crankcase emissions routing and engine compliance.
The blowby hose routes crankcase blowby gases — combustion pressure that escapes past the piston rings — back into the engine intake system rather than venting them to the atmosphere. This keeps the engine bay clean, prevents oil mist from accumulating on external components, and ensures the engine maintains correct crankcase pressure. When this hose cracks, collapses, or pulls loose from its fittings, the engine may develop oil leaks, increased oil consumption, or visible smoke from the crankcase area, all signs that the hose needs immediate replacement.
