OHOB-COOL Straight Silicone Reducer Hose ,ID 1 1/4"- 1 3/4"（32mm-45mm）,Length 3"(76mm),4-Ply (5.25mm) Reinforced Turbo/Intercooler/Intake Piping Coupler Industrial Hydraulic Hoses Black

Built for performance and durability under real-world under-hood conditions, this LUXERAD silicone straight coupler hose is engineered for turbochargers, intercoolers, intake piping, and industrial hydraulic systems. Made from 100% high-grade, heat-resistant silicone with embedded aramid-reinforced fibers, it handles extreme temperatures—from -65°F to +350°F—without cracking, swelling, or degrading. The precision-molded 4-ply construction (5.4mm wall thickness) delivers superior burst resistance and pressure stability versus standard 3-ply (4.5mm) hoses—ideal for boosted applications where reliability matters most. Its smooth inner bore minimizes airflow restriction, while the black matte finish resists UV fading and oil exposure. Installation is straightforward: simply slide over barbed or flanged fittings and secure with high-temp T-bolt clamps (not included). All LUXERAD couplers are hand-inspected, pressure-tested, and backed by our 100% satisfaction guarantee—if you have questions or need fitment advice, our U.S.-based support team is ready to help.
