Frequently Asked Questions
Do I need clamps, and what size should I use?
This hose ships bare — you'll need hose clamps sized for 1.00" tubing to secure it. Stainless steel worm-gear or t-bolt clamps work best for engine bay temperatures.
Can I use this for fuel line or brake line applications?
No. This is engineered for coolant, water, boost, and intercooler circuits. Fuel and brake lines require DOT-spec hose — do not substitute.
How do I prep or cut this hose before installing?
Use a sharp utility knife or hose cutter for clean ends. Teflon tape on barbed fittings helps with sealing. Soak the hose in warm water for 30 seconds before pushing onto fittings — it softens slightly and seats better.
