Oetiker Clamps

The crimp styled clamps have been around for over 75 years. Oetiker patented this and improved the original design over the years to perfection.  There is now a 360 degree clamping action around the hose ensuring the rubber is squeezed uniformly around the hose barb.   This is the best clamp once you have the hose and barb sized accurately as a mate.  This has been done with this pair when combined with the GTH hose.  Note - It is best not to overtighten on a barbed fitting. Made in the USA.
