Frequently Asked Questions
Do I need clamps, and what size should I use?
Clamps aren't included — you'll need hose clamps to secure both ends. Use clamp sizes appropriate for your 3-inch and 4-inch connections; stainless steel clamps are ideal for durability.
Can I use this for coolant, boost, or vacuum lines?
Yes. Silicone handles all three, including boost pressure and vacuum draw. Confirm your system's pressure rating matches silicone's capability on your specific application before installation.
Will this hose fit my existing connections without modification?
The taper is designed to connect 3-inch and 4-inch ports directly. Test-fit it in place before ordering clamps to confirm both ends seat properly on your fittings.
