Air Tube Outer Diameter Specifications
1. φ4 / φ6 / φ8: Micro/fine-adjustment air lines. Primarily used for low-flow control circuits such as dashboard air pressure gauges, pneumatic solenoid valve control ports, and seat airbag adjustments.
2. φ10 / φ12: Standard medium-duty air lines. Commonly used for intermediate actuation circuits, such as pneumatic gear-shifting assistance for transmissions (e.g., the aforementioned ZF AMT system), clutch boosters, and air dryer inlets.
3. φ16: High-flow main air lines. Specifically used for critical safety circuits with stringent requirements for rapid inflation and deflation speeds, such as the vehicle's main brake master cylinder, main air reservoir supply lines, and primary brake chambers.
Classification of Quick-Connect Fittings
1. Explosion-proof quick-connect fittings: Designed specifically for high-pressure and harsh environments. The fitting body and internal locking claws are reinforced to withstand sudden pressure surges, preventing the air hose from detaching or bursting open under conditions of heavy vibration or extreme cold.
2. Double-layer quick-connect fittings: Feature dual internal O-ring seals and double-layer anti-detachment locking claws. Designed for use with double-layer composite high-pressure air hoses or in high-vibration areas, they provide redundant sealing and ensure an exceptionally low leakage rate (approaching zero).
Spiral Tubing and Clamps
1. Sinotruk Pneumatic Spiral Tubing: Features excellent tensile resilience, as well as resistance to oil and aging. It is commonly used at the connection point between the tractor and trailer (near the 7-core cable area) or for chassis pneumatic lines that require frequent, wide-range swinging or stretching.
2. Pneumatic Tubing Clamps: High-strength stainless steel or galvanized carbon steel hose clamps. These are used to secure traditional push-fit barbed connectors, preventing cracking at the tube base and leakage of air or oil under high-pressure conditions.
