396PEEK O-rings or seals are often used together in high-temperature, high-pressure environments. The selection of O-rings or seals is particularly important in the oil and gas extraction industry, which is often subjected to severe working environments, because PEEK materials are resistant to high temperatures, high pressures, chemicals, and fatigue, and can meet the challenges of complexity and variability
