Frequently Asked Questions
What clamps work with this hose?
T-bolt or band clamps rated for 3.75" diameter. Stainless steel or zinc-plated clamps prevent corrosion. Tighten in a cross pattern to avoid pinching the silicone.
Does this hose come with end fittings or adapters?
Straight hose section only—no fittings included. You'll source elbows, barbed adapters, or threaded couplers separately to connect your coolant or boost lines.
Can I use this for both coolant and boost lines?
Yes. The 3-ply silicone handles coolant loop temperatures and intercooler boost pressure. Confirm your system's max pressure rating against the hose's burst tolerance before final installation.
