EilxMag Air Line Kit for Air Spring Suspension — 30ft PA12 Hose, Brass Fittings & Schrader Valves

EilxMag Air Line Kit is a complete 30-foot PA12 air hose set with brass DOT-approved fittings and Schrader inflation valves for installing and connecting air spring suspension systems.

This kit supplies the core components needed to route, join and inflate vehicle air springs: flexible 1/4" PA air line, brass push-to-connect and swivel elbow fittings, a union tee, two 1/4" Schrader inflation valves with caps, and a plastic tubing cutter for clean, reliable installations. Components meet DOT and SAE J844 requirements for air brake system materials, offering resistance to abrasion and impact so lines stay intact under normal road stresses.

How does this kit make installing air spring bags easier?

The kit groups every common small-part item installers need into one package so you avoid multiple trips to suppliers. Pre-sized 1/4" OD tubing and compatible 1/4 NPT threaded brass fittings fit many air spring setups, and the included tubing cutter speeds clean, leak-free connections.

• 30 feet of 1/4" PA12 air line sized for standard air spring ports
• 360° swivel 1/4" OD elbow fittings for tight routing
• Push-to-connect straight fittings for fast joins and disassembly
• Plastic tubing cutter for square, burr-free cuts

What materials and standards define the hose and fittings?

The air hose is manufactured from PA12 polyamide, chosen for flexibility, abrasion resistance and compliance with DOT and SAE J844 air system specifications. Brass fittings resist corrosion and provide solid threaded connections; the Schrader inflation valves are brass as well to withstand repeated use and road exposure.

• PA12 polyamide hose—flexible and impact resistant
• DOT and SAE J844 material compliance for air systems
• Brass push-to-connect, elbow and union fittings for durability
• Brass Schrader valves with protective caps to keep contaminants out

Can I use this kit to tie multiple air springs together or create a single inflation path?

Yes — the included 1/4" union tee lets you combine multiple air spring lines into a single supply route for synchronized inflation or simpler valve access. Threaded 1/4 NPT fittings match many common inflation points; ensure your existing ports accept 1/4 NPT before assembly.

• 1/4" union tee enables single-path or split-path layouts
• 1/4 NPT thread standard fits most air spring ports (verify port size first)
• 360° swivel elbows help route lines around frame or suspension components
• Protective valve caps reduce dirt ingress at inflation points

How do I maintain leak-free performance and what tools are included?

Clean, square cuts and fully seated push fittings are key to leak-free lines; the included plastic tubing cutter delivers consistent cuts. Periodically inspect fittings for corrosion or looseness, and keep Schrader valve caps in place to stop grime from affecting seals.

• Use the supplied cutter for even, burr-free hose ends
• Hand-tighten brass fittings, then test with soapy water for leaks
• Replace caps on Schrader valves when not in use to block debris
• Check hoses for wear or compression after heavy road use

Who is this kit intended for? EilxMag designed this air line kit for DIY mechanics, professional installers and vehicle owners fitting or repairing air spring suspensions on trucks, vans or trailers. It suits anyone who wants a single, compliant package with tubing, fittings, inflation valves and a cutter—especially useful when routing lines through tight spaces or tying multiple springs to one inflation source. Note: verify port threads and system compatibility before installation; use recommended safety precautions when working under vehicles.
