Silicone Coolant Hose

Flexfab industrial silicone coolant hose is built for cooling systems that run hot, vibrate hard, and can't afford downtime. Compared to standard rubber, silicone holds its shape and flexibility through extreme temperature swings, resisting the cracking, hardening, and swelling that lead to leaks and premature replacement. Our lineup covers the full range of coolant routing needs: straight 3-ply and 4-ply hose for general and higher-pressure applications, formed 90° and 45° elbows for tight engine compartments, wire-reinforced hose that resists collapse under suction, and beaded connectors that improve clamp retention on tube ends.

Every Flexfab coolant hose is engineered and manufactured in Hastings, Michigan, backed by decades of experience supplying OEMs and industrial equipment builders.
