1" Heavy Duty Double Gripping Nylon Plastic Hose Clamps, 225° F / 200 PSI Rated, 10 Pack (Made in USA/UK)

Sturdy and work well. I use them on 3/4” hose on barbed fittings. Have >500 gal/hr moving through it with a bit of back pressure due to nozzles used.

Good price, works well.

Used this clamp on an air hose for my car worked like a charm. I put ample amount of strength with my pliers thinking it would snap closed up nice did the trick. Let me give it a couple of months and I will re-evaluate.

Best ckamp i have ever seen. Works great, better than the metal ones. We used in pool, no more rot.

I needed two sizes of hose clamps and I found one of them on Amazon but the search didn't find the other. So I saw the company was KoolerTek. So I tried their url. Sure enough they maintained a extensive website, with a contact page that puts other sites contact pages to shame.So I emailed them at like 6AM getting ready to go to work. BAMM three minutes later I get a reply from a guy named Nathan. He sends me the direct Amazon links to the clamps I need in like three minutes. At six o'clock in the morning! So yeah if I were able to give them 10 stars I would! But with only 5 you still get the picture.Where ever you are Nathan, Thank You Sir! My fish and coral made it!

I must agree with the other one star review stating a minimum and maximum outer diameter hose size absolutely should be stated in the product description. The ad description that was presented to me simply stated this to be a one inch hose clamp. No other sizing related information regarding either the I.D. or the O.D. of the hose to be involved was in the information. As the ad claims these are made in the "USA/UK" whenever a one inch hose is referred to in the USA it means a one inch INSIDE hose diameter, not a one inch outside diameter! i.e. A "1 inch barb fitting" fits a one inch I.D. hose. These "1" Heavy Duty Double Gripping Nylon Hose Clamps" have to be used on 3/4 inch I.D. hose, not 1 inch I.D. hose. Even then, because no minimum or maximum range is given, you are taking a chance of a poor fit.

Solid product. As advertised and delivered on time

Quality appears decent but... I ordered these a little oversized due to some of the confusing product reviews & lack of info from the seller/manufacturer. What a MISTAKE! I needed these for my garden hoses to be able to splice them together when they split or crack. The 1" will NOT fit on a garden hose (~.875 diameter)! The working diameter for the 1" is ~.95 to ~1.07 diameter. The seller/manufacture NEEDS to put a MINIMUM & MAXIMUM 'working diameter' in size description. At $12 and change not worth sending back. Might be able to use a piece of bicycle tubing to adapt or will just throw them in a box and go down to Home Depot or Lowes for what I need! Also, seller/manufacturer should offer a mixed bag of these (i.e. 2 each at .75 thru 1.125 or something similar) for those folks who might need different sizes for desired fit. But that's probably asking way too much!
