Frequently Asked Questions
What hose clamps do I need for this?
Standard worm-gear or t-bolt clamps sized for 4.00" diameter hose will work. Most builders use clamps rated for hose sizes in the 3.5" to 4.5" range — verify clamp sizing against your hose before assembly.
Can I use this on a supercharger or turbo boost line?
Silicone hose is rated for high temperatures. Confirm maximum pressure rating for your specific application — some forced-induction setups demand reinforced braided lines instead. Check your turbo or blower manufacturer's hose specs.
Do I need to prep or seal the connections before installing?
No prep needed on the hose itself. Ensure clamp surfaces and hose barbs are clean and dry before tightening clamps. Tighten securely but do not overtighten — excessive force can distort the barb connection.
