Silicone Straight Hose

Silicone Coolant Hose (continuous length) provides reinforced, heat-resistant performance for coolant, water and low-pressure air duties in automotive, motorsport and industrial systems. Produced by AutoSiliconeHoses using premium silicone with multi fabric cord reinforcement, the design balances flexibility with pressure stability to withstand vibration, pulsation and thermal cycling. A smooth internal bore promotes efficient flow and stable system back-pressure, supporting effective heat exchange across radiators, heater cores and auxiliary circuits. Rated for continuous operation from -50°C to +180°C (with peaks to +250°C), the red continuous silicone hose resists ozone, weathering and common under-bonnet contaminants. Offered in core sizes from 13 mm to 51 mm and manufactured to SAEJ20R3, it delivers consistent, professional-grade reliability with colour coding that aids quick circuit identification and maintenance.

The reinforced laminate restrains growth under pressure to preserve hose roundness and clamp compression, reducing leak risk over service life. Silicone’s low compression set and thermal resilience help maintain fitting integrity across heat-soak and cooldown cycles. The smooth bore mitigates turbulence, supporting stable pump operation and consistent coolant velocities, while the tough outer layer resists abrasion during installation and service. Dimensional control across the range enables secure integration with standard beaded pipes and couplers, simplifying system design and maintenance. Engineered with a typical 3:1 burst margin, the hose supports medium-pressure coolant duties found in modern combustion, hybrid and auxiliary cooling loops.

Use cases include radiator and heater connections, degas and bypass lines, auxiliary pump circuits, charge-air cooling auxiliaries, and general industrial water transfer where thermal durability and colour coding are desirable. The red continuous silicone coolant hose is suited to production, fleet maintenance and performance builds requiring dependable, reinforced tubing for industrial fluid handling and automotive cooling applications.
