What fittings do I need to connect this hose?

You'll need hose clamps and barbed fittings to match your 3.00" diameter ports. The hose itself is straight tubing — clamp it to your radiator, water pump, or custom manifold using standard automotive hose clamps.

Can I use this hose for coolant and other fluids?

Silicone handles coolant well. For other fluids, confirm compatibility with your specific application — coolant and water circulation are the primary use case.

Does this hose come pre-cut or can I trim it?

This is a hose section sold as-is. You can cut it to length with a sharp blade or hose cutter if needed, but measure twice — once cut, it cannot be lengthened.
