I get asked a lot why I prefer Knipex Cobra pliers to other water pump pliers. My answer is simple: Knipex cares about their customers. They design their tools with longevity in mind, even offering replacement parts so you don’t have to throw out a perfectly good tool when a small part fails.
For example, if the push-button assembly on your trusty Knipex Cobra pliers malfunctions, you don’t need to buy a whole new set. You can simply replace the button and get your pliers working like new again.
Durability Meets Repairability
Knipex tools have set a high standard for water pump pliers. Their design for tghe cobras includes only a few moving parts, making them incredibly reliable. However, in rough service situations, the push-button assembly can occasionally wear out, causing the pliers to malfunction.
Thankfully, Knipex offers replacement push-button kits that allow you to extend the life of your Cobra pliers. If the jaws are still in good condition but the button system is failing, a quick replacement is all you need to restore them.
Choosing the Right Replacement
It’s essential to get the right size push-button replacement set for your pliers. The size is typically labeled just like the pliers themselves. For instance, if you have a 10″ Knipex Cobra (model 87 xx 250), the replacement button assembly will also be labeled 87 xx 250.
You can find these replacement kits on Amazon or from reputable Knipex tool vendors like KC Tools. I’ve personally replaced the button assembly on my 10″ Knipex Cobra once when the jaws stopped opening smoothly. After the replacement, it worked just like a new set—no exaggeration!
Pro Tip: Secure the Replacement Properly
When installing a new push-button assembly, make sure to apply a small dab of threadlocker to the screw. This will prevent it from coming loose over time. I use Loctite, but you can go with your preferred brand. This simple step ensures that your repair lasts as long as possible.
Final Thoughts
Knipex Cobra pliers are a solid investment for professionals and DIYers alike. Their durability, coupled with the option to replace worn parts, sets them apart from other water pump pliers. Instead of tossing out a broken tool, you can easily bring your Cobras back to life and continue using them for years to come.
However, if the jaws are worn out or broken, you will need a brand new set. But even then, you can still get your broken cobras replaced for free if they are still under warranty.
