Automotive Exhaust Solutions:
- 409-grade flex pipes absorb engine vibration (±5mm axial movement)
- 310S exhaust pipes resist turbocharger backpressure erosion
Industrial-Grade Durability:
- 2 1/2 Sch 10 pipes with 1,200 psi rating for compressed air systems
- Triple-layer braided flex hoses (internal corrugation + wire mesh + silicone jacket)
Surface & Safety:
- 120 mesh polished surfaces reduce exhaust turbulence
- Salt spray tested per ASTM B117 (1,500+ hours)
