View Catalog Page in PDF format

These clamps prevent extrusion of the silicone hose cover through the slots found on standard worm-drive (screw-type) hose clamps. The inside of the clamp is fully-lined with a smooth, non-perforated band to prevent hose damage. The liner even protects the hose from the sharp edges of the adjuster crimp. Sold individually.

*Please Note:
These recommendations are appropriate for our thick-wall Silicone Coolant and Turbo Intake Hoses. Thinner-wall hoses may require a smaller clamp. If you are unsure, measure the outside diameter of your hose AFTER it is installed on the tubing.

Protect yourself from scratches by covering the loose clamp end with a Rubber Hose Clamp End Jacket, Part No. 3615-500 (sold separately). The .500" size will fit all of the 1/2" wide clamps. This size can also be stretched to fit on the 9/16" wide clamps.

Made in Mexico...

I needed some high quality clamps for my turbo couplings. Pegasus usually has pretty good hardware. However these clamps were not. I ended up not using them. After some more searching I found some USA made Breeze Liner clamps that were the size I needed. Actually I thought that's what I was buying from Pegasus. I should've asked. There is a noticeable quality difference between these Mexico made clamps and Breeze clamps. The biggest of which is how smoothly Breeze clamps tighten and how these clamps do not. Every time I thought the clamp was tight it was just the screw mechanism binding up. These clamps will work, but if you're looking for top quality clamps I suggest looking elsewhere.

Heavy duty, but a bit clunky for my application

It worked well when I had lots of room for it. But, in a few spots my flange was kind of small and I had to use a thinner clamp. I had some narrow with rolled edges and no holes, so they were ok with the silicone.

Great clamps will not damage hose if over tightened

Prevents damage to silicon hoses

Had to use silicone spray to stop hoses from leaking even w these clamps. Probably need to put a bead on all my aluminum tubes to prevent leaking w silicon hose.

I did not feel the clamp was sized properly. My concern began when I began tightening. Never felt secure. May work on a softer hose but did not for my application.
