3-Ply Silicone Hose 1.00" to 1.25" Reducer Black/Red

Do I need clamps to install this hose?

Yes. This hose requires clamps on both the 1.00" and 1.25" ends. Spring clamps or worm-drive clamps work depending on your space constraints — measure twice before ordering clamps.

Can I use this for a radiator or heater hose setup?

It's rated for coolant flow, vacuum lines, and intake applications where temperatures and pressures stay within silicone limits. If you're unsure whether your system's pressure or temp matches, check your vehicle's cooling diagram first.

Will this hose need prep before I connect it?

Clean the barbed fitting ends and hose bores with a clean cloth to remove dust. No adhesive or sealant is needed — mechanical clamp pressure does the job if you tighten properly.
