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.
Products received may vary slightly from images due to manufacturing tolerances or supply chain variables.
