2.25" x 8" 3-Ply Silicone Hose - Black
Heavy-duty silicone radiator hose rated for high-temperature coolant lines. Three-ply construction delivers durability under pressure and heat cycles. Black silicone resists UV degradation and maintains flexibility in extreme conditions.
Will this fit my radiator hose setup without couplers?
The 2.25" diameter matches standard radiator hose sizes. Measure your existing line before ordering — if yours is 2.25" ID, this slides over a barbed fitting without adapters needed. If your setup runs larger or smaller, you'll need a tapered coupler.
Can I use this for a custom coolant line I'm building?
Yes. Silicone hose works for both OEM replacements and custom builds. Slide it over barbed fittings and secure with stainless hose clamps rated for your pressure. Test-fit before final assembly to confirm diameter match.
Does this need prep or coating before installation?
No prep needed. Install straight out of the box. If you're running coolant through it, flush the interior with water first to clear any manufacturing dust. Clamp both ends securely — silicone creep under sustained pressure is real.
