Molded intake duct projects connecting air-system components, with vacuum, movement, ports and connection geometry specified.
Identify the hose location in the air path and whether it sees only suction or also positive pressure. Include sensor branches, resonator connections and mounting features on the drawing. A visually similar duct may route air differently or interfere with the surrounding assembly.
State vacuum level, any pressure event, air temperature and external heat exposure. Record engine or equipment movement relative to the fixed air box. If a corrugated section is proposed, define the movement envelope and surrounding clearance rather than treating corrugation as proof of flexibility or collapse resistance.
An intake duct is not automatically a turbocharger charge-air hose, fuel hose or emissions-certified part. Fit, sealing, airflow and durability acceptance should be defined for the actual assembly.
Only a construction evaluated for that pressure and thermal duty should be considered. State the circuit clearly.
Use the photo as context and provide dimensioned positions and orientations relative to defined datums.
These references explain general engineering or regulatory context. They are not Xinwei finished-product specifications, test results or compliance evidence.
SPECIFICATION REFERENCE
These are project discussion inputs. Compound, tolerances and validated performance require agreement for the specific part.
| Selection / definition | Reference and project conditions |
|---|---|
| End geometry | Round/oval profile, ID or axes and clamping lengths in mm |
| Routing | Centerline route, end clocking in degrees and installation datums |
| Ports | Branch diameters, positions and connection details in mm |
| Air conditions | Vacuum/pressure, flow requirement and air temperature in °C |
| Movement | Relative displacement, vibration and available clearance |
| Acceptance | Fit, leak/collapse and required system performance tests |
KNOWLEDGE & SELECTION
Knowledge
A practical procurement guide to the installation details that drawings and material names often miss. Learn what to specify for pump tubing, formed elbows, reinforced hoses, appliance connectors, automotive ducts, closures, flexible seals and gaskets—and where product-family descriptions stop short of proving suitability.

Knowledge
A practical purchasing guide for defining custom silicone tubing, formed hoses, appliance rubber parts, automotive hoses and seals. Learn which dimensions, operating conditions, interfaces, evidence and acceptance criteria to provide—and where visual similarity or a material name cannot establish suitability.
Read guide
Knowledge
A practical B2B selection guide for separating pump tubing, transfer tubing, formed elbows, reinforced hoses, appliance connections, automotive ducts and molded seals. Learn which application conditions to define, what drawings and evidence to request, and why similar-looking rubber parts should not be treated as interchangeable.

Drawing-led automotive hose projects for branched, offset or multi-bend routes that need a complete interface and validation specification.
Small-route hose projects for identified ventilation circuits, with vapor, condensate, oil-mist and connection conditions distinguished.
Formed elbow hose projects for coolant routes where end fit, bend geometry and the actual cooling circuit need review.
