What Kinds of Sealants Are There?

You’ve probably heard the term “sealant,” but what kinds of sealants are there in the construction or oil and gas industry? Sealing materials prevent unwanted dirt, dust, or water from contaminating oil and gas products during processing. In other words, sealants prevent substances from passing through surfaces and joints.

There are many sealants, each sealing material having features that suit unique applications. In addition, they vary in chemical compatibility and temperature or pressure ranges. So, you must use a sealant that matches your application best. The most common ones include silicone, fluorosilicone, nitrile, and fluorocarbon.

Silicone Sealant and Fluorosilicone Sealant

Silicone and fluorosilicone sealants boast wide working temperature ranges. Their flexibility and low-compression features make them a perfect choice for O-rings and molded seals in oil applications. Here are some of their outstanding qualities.

  • Resistant to sun, ozone, and other weather conditions
  • These sealants provide incredible compression properties
  • Wide temperature ranges (-85°F to 400°F for silicone and 75°F to 400°F for fluorosilicone)

Nitrile Sealant

Nitrile is the most economical and widely used sealant in various industries, including oil and gas, automotive, and marine. Its notable benefits for oil seals are:

  • Low compression set
  • High tensile strength and abrasion resistance
  • Standard temperature ranges (-40°F to 257°F)
  • Resistance to silicone greases and petroleum-based oil or fuel

Fluorocarbon Sealant

Fluorocarbon sealants are commonly used in gaskets, lip seals, O-rings, and other molded sealing joints for oil applications. They provide excellent resistance to swell in oxygenated and high-octane fuel blends. Other benefits of fluorocarbon sealants are:

  • High-temperature resistance
  • Standard temperature ranges (-13°F to 446°F)
  • Resistance to gasoline, transmission fluid, and petroleum oils
