Do I need clamps to install this hose?

Yes. Hose clamps are not included — you'll need to source appropriate stainless or worm-gear clamps for your 3.00" diameter application. Size depends on your fitting barbs.

Can I use this on a supercharger or turbo coolant loop?

Silicone handles high heat and pressure cycling well, making it suitable for forced-induction coolant circuits. Confirm your system's max temperature and PSI rating fall within silicone's limits before committing.

Will this hose leak if I don't apply sealant to the fittings?

A proper clamp seal on clean barbs should hold without sealant, but adding a small bead of silicone-safe thread sealant at each connection eliminates seep risk on high-pressure loops.
