Oovivat Pipe Clamps NPS1-1/4 Inches （Φ38MM）- 304 Stainless Steel & Rubber Lin...

Good product. Made well.

Ordered these to secure 3/4 inch copper pipes. The old clamps were all metal, and a leak actually started in the copper pipe due to metal to metal contact. These clamps have a nice, insulated inside that prevents this and helps them from letting pipe slide. They come in set of 10, with 20 screws and a nice touch of a Phillips bit. They are a bit pricey at over $1 each but will be worth it by stopping formation of leaks.

I got these to secure a pipe in my basement. It ‘hangs’ a 3” pipe with some space around it as I would expect. The strap is about ¾” wide, which is wide enough to not dig into a pipe. It is very bendable, so if you need to put the final tab/screws at a weird angle, that will not be problem. The rubber sleeves are a snug fit on the strap, so they stay in place. I was actually pleased to have the self-tapping hex screws provided, saving me from having to locate some. The seller also went so far as to include the hex driver bit, which was a nice surprise; all I needed was my drill for the install.

These are perfect for attaching 4 inch ducting, both flexible and ridged to my walls and ceiling. Using this as part of my dust collection system for a wood shop. These are a great size and come with some good, robust hardware. I appreciate that they have a "rubber" cover to it is snug but not metal on metal or metal on plastic.

They are true to size. At least the 1/2" clamps i received. They measure a true 7/8" ID. The rubber coating is a tad on the thin side though. Its half the thickness of pretty much all the other clamps like this that I have used. I'm not sure if it really matters though, although if there was a spot that might vibrate or chafe (mobile installation) I would prefer the thicker EDPM rubber of a better quality clamp. If you dont need that protection and cost is your biggest factor, I would use these if they are significantly cheaper than other brands. They would have to be cheaper by a fair margin though...

Just seems overpriced at $14.99 for a pack of 10. I have a pipe at the side of the house that is already clamped but not sufficiently well and I needed these to match. Not the easiest thing to find. So I was happy to get these for review. They are well made and good quality. They come in various sizes and serve their purpose. But the price, for me, is too high. A pack of 10 should not cost more than $10...if anything they should be like 50-60 cents each at most! So yes, I recommend ....on sale!

The brackets themselves are nice. Seem sturdy. Just make sure you get the right size. I saw "1 1/2 in" and thought it would fit my "1 1/4 in" PVC pipe with room to spare, but I got the size mixed up with the schedule and turns out they are too small.

I ordered these pipe clamps to secure 1 1/2” pvc conduit in my garage. The big box store sells a plastic version, but to me they seemed fragile and vulnerable to failure. These straps/clamps, on the other hand, are built tough. The metal of course provides a nice solid surface to keep the screw head from popping through while the rubber like liner squeezes the pvc tight. I don’t know if I used them as they are intended to be used, but they are working great for me. These clamps are easy to install and they have enough flex to be manipulated in awkward spaces. They fit my pvc great.
