PEEK O-rings or seals are special parts used in machines that work in very hot and high-pressure places. They are important in the oil and gas industry, where conditions can be really tough. PEEK materials are strong because they can handle high heat, pressure, chemicals, and wear, making them perfect for these kinds of jobs.
Here's a simpler breakdown of the different types of PEEK O-rings or seals:
