Frequently Asked Questions
Do I need hose clamps to install this?
Yes. Silicone hose requires clamps at both ends to seal against barbed fittings or adapter ports. Stainless steel clamps rated for the pressure in your system are standard practice.
Can I use this on a pressurized cooling system?
This hose is rated for the temperature and material compatibility, but maximum pressure depends on your clamp quality and fitting design. Test your circuit pressure before finalizing the install — coolant systems typically run 15–20 psi.
What length do I need?
Measure your routing from barb to barb and add 1–2 inches for clamp overlap and potential re-routing. This product is sold by the foot — order the length that matches your plumbing run.
