Frequently Asked Questions
Will this hose work with clamps I already have?
The 3.5" diameter fits standard hose clamps in that range. Verify your current clamp size before ordering — undersized clamps won't seat properly on silicone's smooth surface.
Can I use this for a radiator coolant line or just custom builds?
Silicone hoses work in both stock cooling systems and custom setups. Confirm compatibility with your specific application before installation — some OEM systems have design requirements that favor factory hose types.
Does this come with end fittings or adapters?
Hose only — no fittings included. You'll need to source adapters that match your line diameter and port thread size.
