FREIGHTLINER 1221425002 Part Description
Manufacturer
Features & Benefits
- Consolidated 15-port block design to eliminate multiple firewall penetrations and simplify air line management
- Mixed-diameter port interfaces to accommodate varying line sizes for brakes, seats, and horns
- Internalized O-ring sealing system to maintain cab pressurized integrity and block moisture intrusion
- Engineered composite housing to resist thermal fatigue and cracking in high-heat engine bays
- Standardized Cascadia mounting points to provide a direct bolt-on fit without modifying the firewall
Freightliner Pass-Through Air Manifold
The Freightliner Pass-Through Air Manifold serves as the central junction for pneumatic lines crossing the firewall on Cascadia and M2 chassis. Engineering this block with a high-density port layout allows the Freightliner 1221425002 to manage 15 individual air circuits, including primary and secondary brake feeds, without requiring multiple holes in the cab structure. This consolidated design utilizes internal O-ring seals and mixed 1/8", 1/4", and 3/8" ports to maintain a gastight barrier while preventing hose chafing. Choosing a genuine manifold over individual fittings eliminates disorganized "spaghetti" routing and simplifies leak detection in high-vibration engine environments.
