1/4in DOT Airline 30ft

The 1/4in DOT Airline 30ft from RIDETECH is a heavy-duty pneumatic hose designed for air suspension systems, air tools, and compressed air delivery applications in automotive, industrial, and workshop environments. This 30-foot airline serves as the backbone of air system installations, connecting compressors to components with reliable, leak-free performance. Whether you're building a custom air suspension, installing pneumatic tools, or maintaining existing compressed air networks, this DOT-certified airline meets regulatory standards for safety and durability.

Constructed from durable black plastic, the 1/4in DOT Airline features a 1/4-inch inner diameter engineered to handle standard pressure loads while minimizing pressure drop over its full 30-foot length. The plastic tubing resists UV degradation, moisture intrusion, and temperature fluctuations common in garage and outdoor installations. DOT certification ensures the hose meets Department of Transportation safety specifications for compressed air transport, making it compliant with industry codes. The lightweight design at 0.88 lbs allows for easy routing through engine bays, suspension components, or workshop spaces without requiring excessive support or reinforcement.

Technicians, fabricators, and DIY builders installing air suspension systems will find this airline essential for connecting manifolds, accumulators, and air springs with consistent performance. The 1/4-inch diameter is ideal for moderate flow applications where space is limited; for higher-volume systems, larger diameter lines may be required. Installation requires standard push-to-connect fittings or barbed connectors compatible with 1/4-inch tubing—ensure all connections are tight and tested for leaks before pressurizing. This product ships as a single 30-foot spool, offering flexibility to cut and configure the line to your specific layout requirements.
