    • Astro quality
Get this first. I bought a cheaper brand that came with a bunch of other pliers, broke before it removed 2 clamp. Bought the Astro and removed my Clamp with ease. Save time and money and get the quality Astro

    • These are by far the best. Better than Snap On Better than Blue Point ...
I bought these some time ago... At least 2 years. I am an auto technician by trade and I have used several different brands of cable type "remote" hose clamp pliers. These are by far the best. Better than Snap On Better than Blue Point Better than Craftsman Better than the very expensive pair of S-K pliers that I bought (turns out those are re-labeled Mayhews anyway). Though I will say I like the handle on the Mayhew/S-K pliers better. Why is this particular Astro remote hose clamp pliers tool better? Two reasons: The cable is the thickest I've used on ANY of these type that I've used before. I've used it hard for what must be going on 3 years now and haven't noticed any real cable stretch. Every other pair of pliers I've used have noticeable stretch after 6 months. After 1 year, most become stretched beyond usefulness. And it has a threaded adjustment to compensate for any stretch or to just better fit whatever specific spring clamp you happen to be working with. The end that grips the spring clamp itself is a lower profile and seems to grip better than the others I've used as well. The only downside is it seems it takes a lot more effort to compress the handles and release the lock than on some of the other competitors' products. A small trade off for a tool that is otherwise far superior in the important ways. Also, after a couple years of hard use, I broke the spring for the locking lever. I now have to lock the lever manually. No big deal. I still keep on using them. There's a part of me that is tempted to install this Astro cable setup on my old pair of S-K branded Mayhew pliers. That would be the best of all worlds. UPDATE: It's almost 2020. A couple years ago I did infact transfer the Astro cable setup to my S-K/Mayhew pliers and continued using it. Handles definitely work a little easier than the original Astro purple handled ones I had. The locking mechanism tends to skip at times, though. The cable itself is now sticking pretty good and has become a little more time-consuming to use, but it refuses to give up. I have never had a cable last this long. All the previous pliers I've used typically only get me about a year's worth of near daily use until the cable stretches to being not so usable. The profile of the clamp is also better than the others I've used. So, I'm back to order a replacement pair. I'm going to leave my S-K handled ones with the old Astro cable on it as a backup and use the new Astros for everyday. This cable has to be nearly 7 years old and gets very frequent use. I'm still flabbergasted that these have held up so well when every other similar cable type pliers have gotten difficult to use within a year. Well-done, Astro. UPDATE April 2020: I purchased my second set in January 2020 after my first one lasted 7+ years and is still functional on my S-K set of handles. The jaw on my new pair sheared the top piece only 4 months into use. Not sure if that's luck of the draw or if Astro's metallurgy/production methods have gone downhill. Definitely a bit bummed after my original set lasted for so long and technically still works, just sticks a bit and is now installed on different handles... Considering downgrading my rating. ... show more

    • It's good. Fair price.
OK. I had a no name spring clamp tool before, this is almost identical, but definitely better in a few important ways. Thicker steel, so presumably stronger. Same for the thicker cable, which is also available as a replacement part. The lock mechanism is similar, but the pawl has two teeth (vs one), and less freeplay keeps the teeth aligned better. The lock/ratchet on the non-astro one seemed soft,, wore quickly and started slipping. I hope and expect this one to last longer. The lock/ratchet on the Astro, like the cheap one, is too coarse. The "sector " has 8 teeth, but only 3 clicks moves the "business end" from full open to full closed, two when actually squeezing a clamp, as the travel is then less due to the thickness of the clamp ears. This is somewhat made up for by having a threaded fine adjustment on the cable. I'd still prefer finer teeth on the ratchet. So, I'd like a thing or two different, but am happy with it. It's pretty good, and, like all Astro tools seem to be, a good deal. This cable thing is almost always better than pliers of any sort. ... show more

    • Amazing Tool That I Could Not Have Done Without
This thing is amazing, I didn't even know they existed until I had such a complicated car repair on a luxury German vehicle. This tool allowed me to reach a hose clamp that would have been otherwise impossible to reach with any conventional plier remover. After trying for several hours I gave up, found this when searching a forum on the repair, 2 days later I had it and it was able to lock on and remove the clamp that I could not reach or even see deep behind the engine, simply amazing. I knocked off a star for quality only because my sheathing has already torn using it to remove two clamps, but I'm sure it is b/c of the cramped quarters and all the sharp edges around it when using it. Still would be nice to not have it rip. ... show more

    • A most important tool for clips on coolant lines.
I spent two days trying to replace small coolant lines which go to the oil cooling assembly using pliers and long needle nose pliers but with no luck. Frustrated without a clue how I was going to get those ltght fitting clamps back on new hoses. Finally I saw these and bought them. It worked and it was tight requiring careful placement of the chops for access to the tool in tight places. After some time and as I got use to the tool it worked and I am set and happy. 2000 Toyota tundra SR5 runs like new, though it needs a paint job. Am thankful I was able to find these. They seem good quality as they did not show any weaknesses. I will keep these and throw them in my special tools box as they have been expensed to this project and will only serve me again later or I will buy another one, ... show more

    • You need this tool, good value, adjustment hints in review
This tool is designed to clamp onto and expand factory hose clamps so they can be re-positioned or removed. This style has the added bonus of being able to get into some hard to reach places thanks to the cable. There needs to be enough room at the clamp for the pliers head. I've fought with those clamps for years and usually mangled them so badly I would end up having to replace them with the screw-type. After using these pliers, I wish I'd bought them a long time ago. I am very happy with my purchase and would buy them again. They really are an excellent value and function well when adjusted properly. At about $30, you really can't go wrong getting these. If you've never used this type of pliers before there are a couple things that might not be obvious right away but will make all the difference: 1. On the end of the cable is a small metal barrel that keeps the cable from just sliding out. The not-obvious part is that the barrel is held in place with an Allen wrench set-screw and is intended to be moved depending on the size of the clamp you're working on. Loosen it up and adjust the length of the cable to adjust the initial jaws opening. 2. There is a threaded tube that screws in or out that will fine-tune the size of the jaws opening. If you do not use these two adjustments, the pliers are not able to work as well as they are designed to. Some of the negative reviews are because the users did not have the pliers adjusted properly. I know I didn't on the first couple clamps and it was very frustrating. I was working on smaller hose clamps and hadn't found #1 (above) yet and was trying to get it to work by just using #2 (above). I had to use way too much force and still could barely get the clamp to release. Once properly adjusted, the pliers worked great. It's been over six months since I bought them, but I'm pretty sure there wasn't much in the way of instructions on the package. Other than that I can't think of anything to complain about. ... show more

    • Worked on a small clamp
I am working on a 2003 Dodge Durango and it needs the power steering hoses replaced. The return hose goes from the steering rack straight to the reservoir and is secured with a pinch clamp. The ears were on the bottom and I could not get a pair of pliers on it. I heard of these type of hose clamp pliers but, never had to use one. A lot of comments were reported that most of these units are cheaply made and won’t work on small clamps. I decided on the one made by astro. Probably because all their tools are made excellently. Took me less than 5 minutes to unpack, figure this thing out and remove the hard to get to clamp. The unit is well made with what appears to be a powder coating finish. The clamping portion turns so you can easily position it with one hand while operating the clamp. One has to squeeze it enough to engage the locking pawl. This locks the clamp in an open position. Very happy with this purchase and recommend it. ... show more

    • Not Suitable For Clamps Over 2 Inches
Will not open to 2.5 inches as described. Only opens to 2 inches and is not strong enough to open a 2 inch hose clamp. The primers work on smaller Corbin clamps, just not the big stuff.
