Graham-Field3084DZ Grafco Hoffman Screw-Compressor Clamp for Flexible Tubing, Open Style, 5/8" x 3/4", Pack of 12

Quality and the ease of use highly recommended for anyone who has fountains or fishpond that you can attach to tubing without having to disconnect the tubing and reduce the water pressure.

The clamps work well and hold tightly. I tightened them down with pliers and they hang on through some pretty rough treatment. Just know that some of the structure being clamped needs to be under the screw, to keep the plate flat for even pressure.

These clamps are a little grumpy. If you clamp a small hose and the platen gets cocked they start to come apart and hang up. They work pretty well if you make sure to center the hose.

Initially I wasn't too happy about the product because it didn't do the job that well/is cheaply made. It doesn't quite do the job for me because it's a little too cheaply made and the part that clamps down tends to move when tightening the screw which makes it hard for me to use to adjust flow unless positioned in a particular way. As a result, I believe i left a 2 star review based off my own experience/unsatisfactory performance of the product. However, this is now a 1 star review based on my experience with them.They follow up with an email saying that they strive for customer satisfaction and would be willing to refund my purchase without return if I was willing to take down my negative review. I obviously agreed to their proposal. HOWEVER, they took down my review in addition to not initiating a refund/follow up. I have sent several follow up emails and have received no response from them. It's one thing to follow up for customer satisfaction, which is great, but it's another thing to lie about what they would do for you in order to preserve their ratings/image.

A little too chewy for me

I needed this compressor clamp to act as mini-c-clamps and with a slight modification (removing the pressure plate) I was able to and all of my problems were solved!

Nice sturdy little clips. I spray painted them with some Rustoleum Hammered finish paint and used them as "security" to fasten my fender flares to my truck. The front fender flares were attached using the truck's hardware (screws). The rear involved using a pressure fitted clip to pinch the flare to the wheel well opening. These clip worked perfectly. Barely see them.

I purchased these to clamp the floats to the reservior on NEO Manitowoc Ice Machines , they work Great, and keep the float in Place

Very cheaply made. Does not tighten to hold anything. Flimsy. Don’t waste your money......and wasting your money is what you’ll be doing since Amazon won’t do returns on this faulty item.

The small clamps worked well for attaching my insulated skirt under my trailer.

The clamps are good , just a fraction to small for my application.

Very cheaply made, therefore they did not work as advertised.

extremely poor quality
