Frequently Asked Questions
Do I need clamps for this hose?
Yes. This hose requires hose clamps on both the 2.00" and 2.75" ends to secure it to your fittings. Pick stainless steel clamps rated for your application (boost, coolant, or vacuum).
Can I use this for turbo boost lines?
Silicone handles boost duty. Confirm your clamp rating matches your system's maximum PSI before installation — undersized clamps can slip under pressure.
Will this fit my specific diameter pipes?
This reducer steps from 2.00" down to 2.75", so both your donor and destination fittings must match those diameters. Measure your existing hose barbs or adapter ports before ordering.
