Frequently Asked Questions

What clamps do I need for this hose?

Standard worm-drive or t-bolt clamps in 3" and 3.5" sizes work here. Grab stainless steel for corrosion resistance in engine bays.

Can I use this for boost lines or just coolant?

Silicone handles coolant, heater, intake, vacuum, and boost applications — check your specific pressure requirements against the hose's rated range for your setup.

Does this hose need any prep before installation?

Run it under warm water or use a heat gun for 30 seconds before sliding it onto barbs — silicone stretches easier when warm and seals tighter as it cools.
