Within a year, nearly every fitting had begun to leak, resulting in countless hours of troubleshooting and repair. This is a costly lesson on the importance of investing in quality components from reputable manufacturers.

Tip 2: Master the Art of Bending; Precision is Paramount. Kinks, ovalization, and inconsistent bends compromise flow and undermine aesthetics. A slight mistake can cause turbulence, pressure drop, and reduced performance of air suspension system. There is the memory of a young fabricator who attempted to bend stainless steel tubing without the proper tools. The resulting bends were misshapen and uneven, detracting from the system’s overall appearance and hindering its performance. A skilled craftsman, armed with a mandrel bender and a steady hand, can transform a straight length of tubing into a work of art, ensuring smooth, unrestricted airflow and a visually stunning result.

Tip 3: Plan the Routing Strategy Meticulously; Accessibility and Protection Matter. Haphazard routing can lead to damage and make maintenance a nightmare. Think of a system where the lines are routed too close to the exhaust manifold, or are left exposed to road debris. The heat and abrasion quickly take their toll, leading to premature failure. A wise installer spends ample time planning the routing strategy, ensuring that the lines are protected from heat, abrasion, and impact, while also remaining easily accessible for inspection and maintenance. A well thought plan ensures the longevity and reliability of the system.

Tip 4: Pressure Test Rigorously; Verify the Integrity. Skipping this crucial step invites disaster. A system may appear flawless at first glance, but hidden leaks can lurk beneath the surface, waiting to manifest at the most inconvenient time. Imagine a show car, its air suspension system meticulously assembled, only to develop a major leak moments before it’s scheduled to roll onto the stage. A thorough pressure test, employing specialized gauges and leak detection methods, can identify these hidden flaws, ensuring that the system is truly airtight and ready to perform. This prevents the system from complete malfunction in important situation.

Tip 5: Address Vibration; Isolation is Critical. Ignoring vibration is a recipe for fatigue and failure. The constant tremors of the road can wreak havoc on rigid lines and fittings, leading to cracks, leaks, and component failures. The implementation of flexible connectors and the strategic use of damping materials can mitigate the effects of vibration, extending the lifespan of the system and ensuring its long-term reliability. A system with good vibration isolation reduces the noise and increases safety for the vehicle.

Tip 6: Verify Compatibility; Matching Components is Crucial. Components must work in harmony. The pressure ratings, flow rates, and electrical signals must be carefully matched to ensure optimal performance and prevent damage. Mismatched components will cause the whole system to malfunction. Ensure everything works with each other will give the installer a piece of mind.

Tip 7: Prioritize Proper Tube Preparation; Cleanliness is Essential. Burrs, scratches, and imperfections on the tube’s surface can compromise the seal, creating a pathway for leaks. Meticulous deburring of each tube end, careful cleaning of the surface, and precise cutting of the tubing are essential steps in ensuring a leak-free system. Skipping on this crucial will cost the user more money and cause headache.
