Frequently Asked Questions
Do I need hose clamps or barbed fittings to install this?
Yes. This is a bare hose section — you'll need barbed hose fittings and clamps (worm gear or spring-style) to connect it to your radiator, water pump, or throttle body. Measure your existing hard line or fitting diameter to match the barb size.
Can I use this to replace a factory radiator hose?
Absolutely. Silicone handles coolant and sustained engine temps without the stiffening and cracking that stock rubber develops over time. Cut out the old hose section, slide this one in with matched fittings, and secure with clamps.
What's the difference between 2-ply and 3-ply silicone hose?
3-ply adds a middle reinforcement layer that resists collapse under vacuum and kinking at sharp bends. If your run has tight turns or you're running higher pressure, 3-ply is the safer choice. Standard 2-ply works fine for relaxed layouts.
