4.00" x 12" Red Silicone Hose - 3-Ply Construction
High-temp silicone radiator hose rated for serious coolant flow. Three-ply reinforced construction handles pressure spikes and vibration without degradation. The 4-inch diameter and 12-inch length fit common cooling system applications where stock rubber fails.
Do I need clamps for this hose?
Yes. Hose clamps are not included — you'll need to source stainless steel clamps sized for 4-inch diameter hose to secure both ends. Spring clamps or T-bolt clamps both work; worm-gear clamps are most common.
Can this handle coolant additives and different coolant types?
Silicone hose is compatible with traditional coolant, long-life glycol blends, and most aftermarket additives. Always verify your coolant type with the hose supplier if you're running something non-standard.
What's the actual temperature limit on this hose?
Temperature spec not provided — reach out directly to confirm exact rating. Silicone typically holds 250°F+ in sustained service, but your application might demand a specific threshold.
