Silicone Hose 3-Ply 1.50" to 2.00" Reducer with 90 Degree - Black

Will this work with both coolant and turbo boost lines?

This hose is rated for coolant systems and intercooler charge air. If you're running it on a turbo intake or boost circuit, confirm your system pressure rating first—most silicone hoses handle boost up to 25–30 psi, but check your setup specs to be safe.

Do I need clamps, or does this come with them?

Clamps are not included. You'll need two hose clamps—one for the 1.50" inlet side and one for the 2.00" outlet side. Pick a clamp size that matches your hose diameter and tighten firmly to prevent weeping.

Can I use this right out of the box, or do I need to prep it first?

This hose is ready to use. Rinse the interior with clean water if you want to remove any manufacturing residue, then dry it before connecting. No sandpaper, primer, or adhesive prep needed.
