3/4in (19mm) ID x 5 ft l ong Silicone Heater Hose

The VIBRANT PERFORMANCE 3/4in ID x 5 ft Long Silicone Heater Hose is a premium-grade silicone coolant line engineered for high-temperature automotive cooling system applications. This 19mm inner diameter hose delivers reliable thermal transfer performance in engine bay environments where standard rubber tubing degrades under sustained heat stress. The 5-foot length provides flexibility for custom routing in engine compartments, whether in classic restoration builds, high-performance street vehicles, or track-duty setups requiring OEM-quality heater circuit plumbing.

Silicone construction resists degradation from continuous operating temperatures that compromise traditional rubber hoses, offering extended service life in harsh underhood conditions. The 3/4-inch ID specification fits standard heater control valve ports and engine block heater outlets across a wide range of automotive platforms. Black silicone color blends with modern engine bay aesthetics while providing UV protection. At 1.9 lbs, the hose remains lightweight without sacrificing wall thickness or structural integrity, making it suitable for both street and competition applications where weight and reliability matter equally.

This hose serves builders and technicians working on engine swaps, cooling system overhauls, or custom automotive projects requiring point-to-point heater line fabrication. The 5-foot continuous length minimizes connector joints—a critical factor in systems where leak prevention directly impacts engine reliability. Buyers restore vintage vehicles, build modified street engines, or maintain performance cars will find VIBRANT PERFORMANCE hose a proven alternative to OEM-specific heater hoses that may be obsolete or cost-prohibitive for custom applications.
