Frequently Asked Questions
Will this hose work with my existing clamps?
Clamp compatibility depends on your clamp style and the OD of this hose — not confirmed in the product specs. Measure the outer diameter where your clamps will seat, then verify clamp range before ordering. Stainless steel T-bolt or worm-gear clamps are standard for silicone applications.
Can I use this for both coolant and boost applications?
Silicone hose handles both coolant and intercooler duty. Check your system's pressure and temperature specs against silicone ratings for your specific application — boost lines and closed-loop cooling have different demands.
Do I need to prep or seal the connection points before installing?
Clean the barb and connection ports with a dry cloth to remove any debris or coolant residue. Light lubrication inside the hose (water or silicone spray) can help the hose seat onto the barb — this is optional but reduces installation friction.
