Vibrant 2042 Polyester Reinforced Silicone Heater Coolant Hose 3/8 in. ID 20 ft

Vehicle Fitment

• Universal - No vehicle-specific fitment. Compatible with any heater core, coolant, or vacuum line application requiring 3/8 in. (10mm) I.D. hose on any car, truck, hot rod, or motorcycle.

Fitment Notes

• This is a universal hose sold by the roll. Fitment is determined by the builder based on system diameter and routing requirements.
• Not suitable for fuel or oil transfer applications. For coolant and vacuum service only.
• Verify 3/8 in. (10mm) I.D. compatibility with all mating fittings and barbs before purchase.
• Use silicone-compatible hose clamps for secure installation. Standard worm-gear clamps are acceptable for most applications.

Features

• Polyester-reinforced silicone construction provides excellent flexibility without kinking across a wide range of routing configurations
• Extreme operating temperature range of -58°F to 392°F (-50°C to 200°C) - far exceeding standard rubber heater hose ratings
• Exceeds SAE J20R3 heater hose requirements for coolant and vacuum service applications
• Gloss black finish delivers a clean, professional appearance in any engine bay or chassis plumbing install
• Silicone construction resists hardening, cracking, and degradation caused by heat cycling, coolant additives, and ozone exposure
• Highly flexible design simplifies installation in tight routing areas without the need for heat guns or pre-forming
• Sold in a 20-foot roll - provides ample material for complete heater core plumbing, coolant overflow lines, and vacuum routing runs
• Compatible with all standard coolant types and vacuum applications found in street and performance builds

Product Description

The Vibrant Performance 2042 is a 3/8 in. (10mm) inner diameter polyester-reinforced silicone heater hose sold in a 20-foot roll. Designed to replace or upgrade standard rubber heater hoses, this silicone hose delivers dramatically superior longevity and temperature performance - rated from -58°F to 392°F (-50°C to 200°C), it handles the thermal demands of high-output engines, boosted applications, and heavy-duty cooling systems with ease. The polyester reinforcement braid provides structural rigidity under pressure and vacuum while maintaining the exceptional flexibility that makes silicone the preferred hose material for both professional builders and serious enthusiasts.

Unlike rubber heater hose, silicone does not harden, crack, or degrade from extended exposure to heat cycling, ozone, or modern coolant additives. The result is a hose that maintains its original flexibility and seal integrity for years longer than OEM-style rubber alternatives. The gloss black finish provides a clean, uniform appearance that complements any engine bay build style, from stock restorations to full custom performance builds. This hose exceeds SAE J20R3 heater hose standards, making it a reliable choice for both street-driven and motorsport cooling system plumbing.

The 20-foot roll provides more than enough material for complete heater core inlet and outlet runs, overflow reservoir connections, vacuum line routing, and additional coolant plumbing on most builds, often leaving usable material for future repairs or modifications. Important: this hose is intended for coolant and vacuum service only and is not suitable for fuel or oil transfer. This is a universal part - compatibility is determined by inside diameter and system requirements. Hose clamps are sold separately. One-year limited warranty included.
