Multi-Lumen Hose | PASS | Integrated Fluid Transfer Solutions
Product Overview
PASS multi-lumen tubes are precision-extruded to create two or more independent flow channels within a single, cohesive profile. We specialize in:
Multi-Lumen Tubes: Feature parallel lumens of the same or different diameters for simultaneous transfer of multiple fluids.
Stepped Tubes (Dual-Durometer): Combine lumens of varying sizes and can integrate different materials (e.g., a rigid section for stability paired with a flexible section for connectivity).
Silicone Multi-Lumen Tubes: Utilize high-temperature silicone rubber for extreme thermal environments, offering superior flexibility and longevity.
This advanced co-extrusion technology allows for custom geometry, material combinations, and performance characteristics tailored to your specific system requirements.
Key Features & Benefits
● Space and Weight Optimization: Replaces multiple single tubes with one integrated component, saving crucial space and reducing overall weight for improved vehicle efficiency.
● Simplified Assembly & Routing: One tube installs faster and easier than multiple individual lines, reducing labor costs and complexity in assembly plants.
● Enhanced System Reliability: Minimizes the number of connections and clamps, thereby reducing potential leak points and improving overall system integrity.
● Material Versatility: Each lumen can be engineered with materials best suited to its function (e.g., Nylon for oil resistance in one channel, TPV for coolant in another). Our silicone multi-lumen tubes excel in continuous high-temperature applications.
● Cross-Contamination Prevention: Provides a secure, leak-proof barrier between different fluids (e.g., coolant and refrigerant) running in adjacent channels.
● Design Flexibility: PASS offers unparalleled customization in lumen diameter, wall thickness, geometry (round, oval, D-shaped), and material selection.

Primary Automotive Applications
PASS multi-lumen tubing is ideal for complex systems where space and integration are critical:
● HVAC Systems: Integrated lines for refrigerant, condensate drainage, and sensor lines within a single unit.
● Automatic Transmission & Powertrain: Combined delivery of transmission fluid, coolant, and hydraulic control fluids.
● Thermal Management Systems: For next-gen EVs and Hybrids, managing battery coolant, refrigerant, and PTC heater lines in close proximity.
● Engine Management: Bundled lines for vacuum, crankcase ventilation, and sensor feeds.
● Fuel Systems: Combined vapor recovery and supply lines.
● Hydraulic Control Units (HCU): Integrated delivery for different hydraulic fluids.
