PEX Crimp vs Sharkbite: Key Differences
PEX crimps are copper or stainless steel rings that help you seal joints in water pipes. This is widely used in plumbing.
SharkBite is also used in PEX tubing works with the same purpose. However, these two fittings have a few differences that you should consider before using them.
Some of the key differences are:
Longevity
PEX crimp and SharkBite, can both serve you for a long time. But the O-rings in the SharkBite are more likely to compress and leak earlier than the PEX crimp. Still, they can work fine for at least 8-10 years. Due to their differences in longevity, people usually go for SharkBite for short-term solutions and PEX crimp for the long term.
Cost
Another major difference is in their cost. SharkBite is a little expensive compared to the PEX crimp. If you have the budget, you can go for SharkBite. Otherwise, PEX crimps are the best solution.
Efficiency
Efficiency is one of the most crucial factors to choose between any two alternatives. They both work quite fine in sealing connections and preventing leakages. But as we said earlier, if you are looking for a long-term solution, then PEX crimps may serve you better.
Usability
When you do plumbing work, you will find some places where you only have to use SharkBite. In such situations, you can go for SharkBite without thinking about PEX crimps.
How Reliable Are PEX Crimps?
As we have told you, PEX crimps are efficient and work well in the long term. So now you may ask, how reliable are PEX crimps?
PEX crimps are heavily reliable for sealing any connection in the water system. The only thing required for that is to set the fittings well.
You will find copper and stainless steel PEX crimp in the market. Which pex crimp is better? Based on our comparison between these two fittings, stainless steel crimps come slightly ahead of the coppers.
Why Do My PEX Fittings Leak?
Have you used PEX crimp fittings, and it is leaking? Well, there can be various reasons behind that.
The most common reason for PEX fittings leakage is the fittings are not done correctly. Then to prevent corrosion, many fittings may use zinc plating. It can build up residue while water flowing, resulting in leakages.
Can Sharkbites Be Used Permanently?
SharkBites have a longevity issue. So, can SharkBites be used permanently?
SharkBites are approved with International Plumbing Code for permanent use. Therefore, you can use SharkBites as a permanent solution to plumbing.
While compared with PEX crimps, SharkBites are less likely to last long. But usually, that’s a rare case.
Why Is My Sharkbite Leaking?
If your SharkBite fitting is leaking, you may get worried. Why is the SharkBite fitting leaking?
The first reason a SharkBite may leak is the fitting itself. Maybe the fitting is not well done. Another reason can be the compression of the O-ring inside. Look inside the SharkBite fitting if the O-ring is okay or not.
How to Use Pex Crimp Tool
If you have decided to proceed with PEX crimp, you will need a PEX crimp tool. The tool is necessary to install the crimp rings in the PEX tubing pipe.
First, cut the pipe according to the size you need. Then push the fitting into the pipe and slide the ring to the edge. Now it’s time to use your PEX crimp tool.
Open the PEX crimp tool by pulling the hands apart. Then set it on one end of the crimp rings and put pressure on it to seal the connection tightly.
How to remove pex crimp clamps? First, squeeze the crimp rings with the tool and then rotate the tool to create an opening. Soon, the ring will slide off.
