Straight Silicone Black Couplers 250/500/750mm Lengths

Straight Silicone Couplers in 250 mm, 500 mm, and 750 mm lengths provide reinforced, high-performance connections for intake, intercooler, turbo, and coolant systems. Manufactured by AutoSiliconeHoses from premium-grade silicone with multi-ply polyester reinforcement, these couplers deliver exceptional heat resistance, flexibility, and durability compared to standard rubber alternatives. The extended lengths allow for greater adaptability in complex installations, eliminating the need for multiple short connectors and reducing potential leak points. Operating within -50°C to +220°C (short peaks to +250°C) and built to SAEJ20R3 standards, these silicone couplers ensure long-lasting performance in demanding automotive, motorsport, and industrial environments.

The Straight Silicone Couplers in extended 250 mm, 500 mm, and 750 mm lengths offer flexibility for a wide variety of custom and professional installations. Their smooth internal bore supports efficient airflow and fluid transfer, reducing turbulence and ensuring consistent system performance. The reinforced wall structure provides stability under boost or coolant pressure while maintaining flexibility for routing in confined spaces. Longer coupler lengths reduce the need for multiple joints, improving reliability and simplifying installation in intercooler, turbocharger, and radiator setups. Resistant to ozone, oil mist, vibration, and high heat, these couplers provide long-term service life in harsh environments.

Applications include intercooler piping, turbo intake and outlet connections, radiator and coolant joins, and general high-performance or industrial fluid transfer where durable, extended-length hose connectors are required. Distributed under the AutoSiliconeHoses brand, Straight Silicone Couplers in 250 mm, 500 mm, and 750 mm lengths provide a robust and versatile solution for enthusiasts, engineers, and technicians seeking strength, durability, and flexibility in silicone hose installations.
