Frequently Asked Questions
Do I need clamps to install this hose?
Yes. Hose clamps are not included — you'll need two clamps (one for the 1.00" end, one for the 1.25" end) to secure it to your barbed fittings or ports. Worm-drive or constant-tension clamps work best.
Can this handle coolant loops, or is it turbo-only?
It's rated for both. Silicone handles coolant, turbo intake, intercooler discharge, and other high-temp fluid applications. Just match your actual hose temps to silicone's heat rating — verify your system won't exceed its limit before install.
Will this fit directly onto my existing barbed ports, or do I need to order adapters?
Test-fit first. If your ports are straight 1.00" and 1.25" barbed, this reducer connects them without additional fittings. If your ports use SAE or metric threads, you'll need barbed adapters — confirm port style before committing to this hose.
