EilxMag Air Line Kit for Truck Air Spring Suspension – 30 ft PA12 Hose & DOT Fittings

Designed for heavy-duty truck and trailer airbag suspensions, the EilxMag Air Line Kit combines a 30-foot PA12 hose with durable fittings to deliver reliable air lines and straightforward service. The kit is built to support flexible routing, easy maintenance, and consistent air delivery as you travel demanding roads.

What’s included

• 30 feet of black 1/4" PA12 air line; compact, flexible, and designed for long life
• 2 brass Schrader inflation valves with protective caps
• 2 1/4" OD x 1/4" NPT elbow fittings with 360° swivel
• 1 1/4" OD x 1/4" NPT straight fitting with push-to-connect
• 1 1/4" union tee to link airbags for a single-path installation
• 1 plastic tubing cutter for clean, precise cuts

Premium materials and compatibility

The 1/4" air line uses PA12 polyamide for excellent flexibility and durable wear resistance, meeting DOT standards and SAE J844 requirements for air brake systems. The nylon hose helps reduce fatigue on long runs while staying pliable in varying temperatures.

• The hose is designed to handle everyday road stress with reliable performance
• Materials and design emphasize corrosion resistance and long-term reliability

Brass fittings with thoughtful engineering

All fittings are brass for strength and durability. The kit includes 360° swivel elbow fittings and a union tee to simplify routing and reduce pipe clutter. Push-to-connect options offer quick, tool-free connections, while protective caps keep dirt out of valves.

• 360° swivel elbows enable flexible, clean routing around chassis components
• Brass construction resists corrosion and wear in demanding environments

Installation and use

The 30-foot length provides reach across axles and along the trailer frame, allowing a single-path installation where needed. The kit supports tying a set of air springs together and simplifies maintenance with clearly defined inflations points.

Whether you’re replacing worn lines or upgrading an existing system, this kit offers parts that feel sturdy and dependable, without promising guarantees—what you gain is the potential for smoother suspension operation and easier service on the road.

Real-world scenarios
