Customers are mixed about the clamp quality. Some mention it's perfect for hose clamps and works well for spring style hoses that are installed in close quarters.

64 customers mention36 positive28 negative

Customers have mixed opinions about the lock of the pliers. Some like that it has a locking mechanism to hold the clamp open for removal. They say it allows them to position the clamp easily. However, others say that it does have trouble locking and the power could be a bit stronger. They also mention that it doesn't lock fully open and closes slightly when the lock engages.

"...The tool has a locking mechanism to hold the clamp open for removal and installation. Good for light use only...." Read more

"...The locking mechanism tends to skip at times, though...." Read more

"...of these, where you can use them, is the fact that you can lock them in the open position and its a lot more solid of a bite than pliers can offer...." Read more

"...The locking power could be a bit stronger, but you can't do without this tool for hard to reach coolant hose clamps." Read more

I love Astros tools, but these aren't the best...
In the photo you'll see a pair of astro and pair of powerbuilt hose clamp pliers. The powerbuilt are made in Taiwan and are significantly better than the Astros. The clamp arms on the end are much bigger and the mechanism is much stronger. Everything about the powerbuilt version is better than the Astros. I have a ton of astro tools in my lineup, so I'm not knocking astro, but these are made in china, and just not as strong as they should be.

I tried another competing item first, but the spring broke after the first use. This Astro-Pneumatic piece is quality. You can see it the first time you pick it up. The only gripe I have is that when you are working with small clamps (less than 1 inch) the adjustment comes up a bit short. That said, it works as it should.

5.0 out of 5 stars These are by far the best. Better than Snap On Better than Blue Point ...
Reviewed in the United States on May 13, 2015
Style: Cable TypePattern Name: Hook SetVerified Purchase
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.

5.0 out of 5 stars A most important tool for clips on coolant lines.
Reviewed in the United States on June 20, 2023

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,

My 1998 VW Jetta ruptured a coolant hose flange (from water pump to oil cooler and engine). So there were 3 clamps to deal with. 2 of them required this tool, which was very important in completing this repair, both getting the old hoses off and putting the new hoses on. The locking power could be a bit stronger, but you can't do without this tool for hard to reach coolant hose clamps.

Style: Hose HooksPattern Name: Hook SetVerified Purchase
This set of hose removal hooks is really one of my best tools for removing or braking loose any old radiator hoses that are stuck. After a couple of years on a vehicle, these hose have a tendency to loose flexibility and getting stuck. These hooks are perfect for getting under them and breaking them loose. It never took me very long to remove any hoses with these. I had successfully removed hoses from radiators, thermostat housing, heater cores and other kind of non-automotive stuff. The metal is of good quality and is strong enough not to deform in any way. I believe that this set of hooks will last me 4ever.
