Frequently Asked Questions
Do I need clamps to install this hose?
Clamps are not included with this segment. Use stainless steel hose clamps sized for 4-inch diameter tubing at each end to secure the hose to your fittings — standard practice for any custom coolant or boost line setup.
Can I use this for coolant, or is it boost-only?
Three-ply silicone handles both coolant and boost pressure without issue. Material resists oil, fuel, and thermal stress equally well, so application depends on your fitting selection and system design.
Is this one piece or does it come with connectors?
This is a straight hose segment only — no connectors, reducers, or adapters included. You'll source fittings separately based on your line diameter and male/female thread needs.
