What hose clamps work with this diameter?

Standard automotive clamps sized for 2-inch hose will work. Stainless steel T-bolt clamps are your safest bet for pressure applications like turbo boost lines.

Can I use this for my radiator or heater bypass?

Yes. Three-ply silicone handles both low-pressure (vacuum) and moderate-pressure (coolant) applications. For high-pressure fuel lines, step up to a fuel-specific hose.

Do I need to seal or glue the connection points?

No adhesive needed—clamps do the work. Make sure hose ends slide fully onto barbed fittings, then tighten clamps in a cross pattern (like wheel lugs) to keep the seal even.
