Vibrant 2047 Nylon Reinforced Silicone Heater Coolant Hose 1 in. 25mm ID 20 ft.

Vehicle Fitment

• Universal - No vehicle-specific fitment. Compatible with any heater core, coolant, oil, water, or vacuum line application requiring 1 in. (25mm) 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.
• Verify 1 in. (25mm) I.D. compatibility with all mating fittings, barbs, and nipples before purchase.
• Suitable for coolant, oil, water, and vacuum service. Not suitable for direct fuel transfer applications.
• Use silicone-compatible hose clamps for secure installation. Standard worm-gear clamps are acceptable for most applications.

Features

• Nylon-reinforced silicone construction provides excellent flexibility and pressure resistance without kinking
• Wide operating temperature range of -65°F to +350°F (-54°C to 177°C) - significantly superior to standard rubber heater hose
• Suitable for coolant, oil, water, and vacuum service across a wide range of street and performance applications
• Exceeds SAE J20R3 heater hose requirements for reliable, standards-compliant installation
• Gloss black finish provides a clean, professional appearance in any engine bay or chassis plumbing build
• Silicone resists hardening, cracking, and degradation caused by heat cycling, ozone exposure, and coolant additives
• Highly flexible design simplifies routing in tight spaces without pre-forming or heat application
• Sold in a 20-foot roll - sufficient material for most full plumbing runs including heater core, intercooler, and overflow lines
• One-year limited manufacturer warranty included

Product Description

The Vibrant Performance 2047 is a 1 in. (25mm) inner diameter nylon-reinforced silicone heater hose sold in a 20-foot roll. At 1 inch I.D., this is one of the larger sizes in Vibrant's silicone heater hose lineup, making it well suited for heater core connections, intercooler coolant lines, oil cooler plumbing, overflow reservoir routing, and other large-diameter fluid transfer applications in both street and performance builds. Rated from -65°F to +350°F (-54°C to 177°C), it comfortably handles the thermal demands of high-output naturally aspirated and turbocharged engines alike.

The nylon reinforcement braid provides the structural backbone needed to maintain hose shape under both positive pressure and vacuum conditions, while the silicone compound itself delivers long-term resistance to heat cycling, ozone, and the full spectrum of modern coolant and oil additives. Unlike rubber alternatives that stiffen and crack over time, silicone retains its original pliability and sealing capability for the life of the build. The gloss black finish is consistent across Vibrant's full silicone hose lineup, providing a unified, professional appearance whether used for a single connection or a complete chassis plumbing overhaul.

The 20-foot roll provides generous material for complete heater core inlet and outlet runs, large-bore intercooler water lines, oil cooler feeds, or multiple vacuum connections without requiring additional purchases. This hose exceeds SAE J20R3 heater hose standards and is suitable for coolant, oil, water, and vacuum service. Not suitable for direct fuel 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.
