How to Pick the Right Chemical Resistant Gasket For Sulfuric Acid 

Picking the right resistant gasket is something you need to take very seriously when you are using sulfuric acid. There are two materials that we generally recommend for this option, and they can be used within a wide range of applications.  

Firstly, polytetrafluoroethylene (PTFE) is a family of materials that you might be familiar with if you have used Teflon before. It is resistant to almost any chemical you might use on a regular basis, which is why it’s relied on in so many industries to this day. As well as being a great option to use in the kitchen, you’ll find that it can coat metal to protect from radioactive material or could be used within food, pharmaceutical, and chemical manufacturing. Generally, this is the first choice material when it comes to using sulfuric acid, but you’ll also need to think about the pressure, temperature, and percentage you are using to find the right solution for your needs. 

The other good option for gaskets in the UK is fluorocarbon elastomers. You might also know these as FKM, FPM, or Viton, and it’s a very versatile solution that can also be used in almost any industry. The great news about this solution is that it’s heat resistant to 200C and is resistant to the majority of chemicals you might use, with the exception of ketones. This solution is regularly used with chlorinated hydrocarbons, acids, or fuels, and therefore is good for sulfuric acid applications that go up to 90%. However, if you do increase this to 95%, keep in mind that it won’t be a suitable option for your needs. You’ll want to think very carefully about how you use sulfuric acid to ensure you are finding a safe and reliable option for your needs. 

Choosing the Best Chemical Resistant Gaskets for Your Business 

Sulfuric acid is most commonly purchase at concentrations of 78, 93, or 98%, so you’ll need to decide which mechanical seals are the best option for the percentage you are purchasing. You’ll need to ensure the design and the fit of the gasket is right for your needs, or it will fail completely, meaning that all of your hard work in selecting a good option was wasted. While the material is very important to consider, also look at the design alongside it to ensure you have the perfect option for your work. You don’t want it to erode the gasket or pose any form of risk to your other equipment or your staff members.
